AB  - Antimicrobial resistance is a global threat, leading to an alarming increase in the prevalence of bacterial infections that can no longer be treated with available antibiotics. The World Health Organization estimates that by 2050 up to 10 million deaths per year could be associated with antimicrobial resistance, which would equal the annual number of cancer deaths worldwide. To overcome this emerging crisis, novel anti-bacterial compounds are urgently needed. There are two possible approaches in the fight against bacterial infections: a) targeting structures within bacterial cells, similar to existing antibiotics; and/or b) targeting virulence factors rather than bacterial growth. Here, for the first time, we provide a comprehensive overview of the key steps in the evaluation of potential new anti-bacterial and/or anti-virulence compounds. The methods described in this review include: a) in silico methods for the evaluation of novel compounds; b) anti-bacterial assays (MIC, MBC, Time-kill); b) anti-virulence assays (anti-biofilm, anti-quorum sensing, anti-adhesion); and c) evaluation of safety aspects (cytotoxicity assay and Ames test). Overall, we provide a detailed description of the methods that are an essential tool for chemists, computational chemists, microbiologists, and toxicologists in the evaluation of potential novel antimicrobial compounds. These methods are cost-effective and have high predictive value. They are widely used in preclinical studies to identify new molecular candidates, for further investigation in animal and human trials.

AB  - Human papillomaviruses (HPV) are the most common sexually transmitted pathogens
worldwide, leading to infections with a wide range of clinical manifestations: from benign
conditions to different types of cancer in women and men as well. Cervical cancer is highly
correlated with persistent high-risk-HPV (HR-HPV) infection, which is the key factor in
emergence of 99.99% of cervical cancer cases. The most effective way to prevent HPV-related
cancers is vaccination. There are three available prophylactic HPV vaccines: bivalent,
quadrivalent and nonavalent. The nonavalent vaccine is gradually replacing other HPV vaccines
in most countries and can be given from year 9, but it is commonly routinely implemented at the
age of 11 to 12. The World Health Organization has recognised cervical cancer as a global threat
and has announced the so-called 90-70-90 strategy to reduce and even eliminate cervical cancer.
This strategy implies that 90% of girls should be vaccinated by the age of 15, 70% of women
should be screened for cervical cancer, and 90% of women diagnosed with cervical disease should
receive adequate treatment. Although different treatment options are available: surgery, radiation
therapy, chemotherapy, and advanced target therapy using monoclonal antibodies, great efforts
are needed to achieve the goals set by the World Health Organization to eliminate cervical cancer.

Najčešći HPV-posredovan karcinom je karcinom grlića materice koji je u preko 99,99% slučajeva posledica infekcije. Najefikasniji način da se spreči razvoj perzistentne HR-HPV infekcije je vakcinacija. Dostupne su tri profilaktičke vakcine: dvovalentna, kvadrivalentna i devetovalentna. Devetovalentna vakcina pruža najširu zaštitu jer sadrži devet onkogenih HPV genotipova i postepeno zamenjuje ostale vakcine u svim zemljama. Sa vakcinacijom se može krenuti od 9. godine, ali se najčešće rutinski sprovodi kod dečaka i devojčica u uzrastu od 11 do 12 godina. Svetska zdravstvena organizacija je prepoznala karcinom grlića materice kao globalni problem i uvela takozvanu 90-70-90 strategiju u cilju smanjenja stope, pa čak i eliminacije karcinoma grlića materice. Ova strategija podrazumeva da 90% devojčica bude potpuno vakcinisano do 15. godine, 70% žena pristupi redovnom ginekološkom pregledu do 35. godine i ponovo do 45. godine i 90% žena sa promenama na grliću materice primi adekvatnu terapiju. Iako su dostupne različite terapije poput hirurškog tretmana, radioterapije, hemioterapije i ciljane terapije monoklonskim antitelima, i dalje su potrebni veliki napori da bi se dostigli ciljevi Svetske zdravstvene organizacije.

AB  - Histone deacetylases (HDACs) are the major regulators of the balance of acetylation of histone and non-histone proteins. In contrast to other HDAC isoforms, HDAC6 is mainly involved in maintaining the acetylation balance of many non-histone proteins. Therefore, the overexpression of HDAC6 is associated with tumorigenesis, invasion, migration, survival, apoptosis and growth of various malignancies. As a result, HDAC6 is considered a promising target for cancer treatment. However, none of selective HDAC6 inhibitors are in clinical use, mainly because of the low efficacy and high concentrations used to show anticancer properties, which may lead to off-target effects. Therefore, HDAC6 inhibitors with dual-target capabilities represent a new trend in cancer treatment, aiming to overcome the above problems. In this review, we summarize the advances in tumor treatment with dual-target HDAC6 inhibitors.

AB  - Humanity is facing a vast prevalence of neurodegenerative diseases, with Alzheimer’s disease (AD) being the most dominant, without efficacious drugs, and with only a few therapeutic targets identified. In this scenario, we aim to find molecular entities that modulate imidazoline I2 receptors (I2-IRs) that have been pointed out as relevant targets in AD. In this work, we explored structural modifications of well-established I2-IR ligands, giving access to derivatives with an imidazole-linked heterocycle as a common key feature. We report the synthesis, the affinity in human I2-IRs, the brain penetration capabilities, the in silico ADMET studies, and the three-dimensional quantitative structure-activity relationship (3D-QSAR) studies of this new bunch of I2-IR ligands. Selected compounds showed neuroprotective properties and beneficial effects in an in vitro model of Parkinson’s disease, rescued the human dopaminergic cell line SH-SY5Y from death after treatment with 6-hydroxydopamine, and showed crucial anti-inflammatory effects in a cellular model of neuroinflammation. After a preliminary pharmacokinetic study, we explored the action of our representative 2-(benzo[b]thiophen-2-yl)-1H-imidazole LSL33 in a mouse model of AD (5xFAD). Oral administration of LSL33 at 2 mg/Kg for 4 weeks ameliorated 5XFAD cognitive impairment and synaptic plasticity, as well as reduced neuroinflammation markers. In summary, this new I2-IR ligand that promoted beneficial effects in a well-established AD mouse model should be considered a promising therapeutic strategy for neurodegeneration.

AB  - The protolytic equilibria of bilastine were studied experimentally and theoretically. The
pKa values were determined potentiometrically at a constant ionic strength (0.1 M NaCl) and
temperature 25 °C. Energy calculation of the optimized structures of the equilibrium forms was
performed at the B3LYP/6-31G (d,p) level of the Density Functional Theory (DFT). The results of
the theoretical study helped to define the ionization profile of bilastine and to assign the
experimentally determined pKa values to the corresponding ionizable groups.

AB  - Montelukast is a leukotriene receptor antagonist indicated for asthma prophylaxis in adults
as well as in pediatric patients 6 months of age and older. Because it is associated with
numerous side effects, including neuropsychiatric events, it is very important to monitor its
pharmacologic behavior when administered chronically. To gain better insight into the
pharmacological properties of ionizable drugs, their physicochemical properties should be
studied under conditions more similar to physiological, such as micellar solutions of
surfactants as biomembrane mimetic systems. Montelukast is an ampholyte with one acidic
(carboxyl) and one basic (quinoline nitrogen) group. In this study the effects of micellar
solutions of differently charged surfactants (anionic SDS, cationic CTAB, and nonionic TX-
100) on protolytic equilibria of montelukast were investigated potentiometrically. Solutions were titrated with standard NaOH solution (0.1017 M) at a constant ionic strength (0.1 M NaCl) and a temperature 25°C. Experimental data were analyzed using the Hyperquad program. Due to poor water solubility, the pKa values defining the ionization in water (pKa1 =4.07, pKa2 = 5.49), were obtained indirectly by extrapolation from the pKa* values determined potentiometrically in the different methanol-water mixtures (40%, 50%, and 55% wt/wt). The pKa values in 0.01M micellar solutions were determined without the use of cosolvent. Micelles contributed to the shift in protolytic equilibria of montelukast, anionic ΔpKa up to +1.20, cationic ΔpKa up to +0.27, and nonionic ΔpKa up to +0.98. More pronounced effects are observed on the ionization of carboxyl group than quinoline nitrogen. A change in the distribution of equilibrium forms in a relation to pure water, can be expected in physiological conditions, in interactions of montelukast with polar or charged biomolecules.

AB  - Rho-associated coiled-coil kinases (ROCKs) are involved in essential
cellular functions such as adhesion, contraction, motility, proliferation, and cell
survival/apoptosis. Four ROCK inhibitors have already been approved by the FDA and
are used to treat glaucoma (ripasudil and netarsudil), cerebral vasospasm (fasudil), and
graft-versus-host disease (belumosudil). Recent studies have focused on exploring the
role of ROCK kinase inhibitors in cancer treatment and the development of new ROCK
inhibitors. The main objective of this study was to identify critical structural features
relevant to the inhibition of ROCK1 using a ligand-based 3D-QSAR (3D quantitative
structure-activity relationship) method. The 3D-QSAR model for ROCK1 was created
and validated using internal and external validation parameters (R2, Q2, R2pred, rm2, r/2m, 𝑟���������𝑚���������
2̅̅̅
and ∆r2m). The main structural features that correlate with the inhibition of ROCK1 were
identified (e.g., heterocycle with hydrogen donor group like nitrogen atom) and further
structural modifications of the ROCK1 inhibitors that contribute to increased activity
were proposed (removal of the amino group of the oxadiazole, modification of the
substituents of the phenyl ring).

AB  - Overexpression of Rho-associated protein kinases has been associated with various
diseases, including tumors. None of the approved ROCK inhibitors are used for cancer treatment.
However, some of them have been shown to have anti-tumor potential. The main objective of this
study was to develop novel ROCK1 inhibitors using the structure-based method, molecular
docking, and prediction of pharmacokinetic properties using the ADMET predictor. The key
interactions that strongly correlate with the activity of ROCK1 inhibitors are hydrogen bonds
between amino acid residues Met156, Glu154 and the hinge region of the inhibitors, indicating
possible structural changes in the hinge region of studied compounds. On the other hand, the
lack of interactions between 1,3-benzoxadiol moiety and the enzyme presents a promising
approach for further structural modifications in order to design more effective ROCK1 inhibitors.
All the important interactions between the developed ROCK1 inhibitors and the binding site
of the enzyme were established. They also showed acceptable pharmacokinetic properties and
could be further used for synthesis and evaluation by various biological assays.

AB  - Histone deacetylases (HDACs) belong to a family of epigenetic enzymes that has 18 different
isoforms and play an important role in the development and progression of various tumors.
To date, five histone deacetylase inhibitors have been approved by the FDA, and are used
to treat multiple myeloma, cutaneous T-cell lymphoma, peripheral T-cell lymphoma, and
breast cancer (estrogen and/or progesterone positive) [1]. All of them are non-selective.
Therefore, their safety profile is poor and their efficacy is low in single therapy. One of our
previous research projects demonstrated the synergistic effect of HDAC inhibitors and
inhibitors of Rho-associated protein kinases (ROCK) in the treatment of pancreatic ductal
adenocarcinoma (PDAC) [2]. This finding led us to design of the dual HDAC/ROCK inhibitors
with potential effects on PDAC by using structure-based molecular docking method.
Molecular docking study was performed using GOLD software. The crystal structures of
ROCK1 (PDB: 6E9W), ROCK2 (PDB: 7JNT), HDAC1 (PDB: 5ICN), and HDAC6 (PDB: 5EDU)
enzymes were downloaded from the Protein Data Bank (PDB). The enzymes were prepared
for docking study using the online software Play Molecule-ProteinPrepare. The structures
of the ROCK1, ROCK2, HDAC1 and HDAC6 inhibitors with their pIC50 values were obtained
from the ChEMBL database. The dominant microspecies of all compounds at physiological
pH were selected by Marvin Sketch Sketch 6.1.0 program and their further geometrical
optimization were performed using the PM3 semi-empirical method and the Hartree-Fock
method with 3-21G basis set.
The virtual docking procedures for all four enzymes were validated and the calculated RMSD
values were below 2Å. The critical parts of the structures that establish the interactions
crucial for the inhibition of HDAC1, HDAC6, ROCK1, and ROCK2 were identified. Based on
the obtained resultsdual HDAC/ROCK inhibitors were designed and evaluated by validated
docking procedures and in silico ADMET profiling.
Taking into account all these findings, the most active compounds are selected and will be
further synthesized and evaluated using in vitro enzyme and cell tests.

The 33 compounds that have a wide structural and therapeutic diversity were analyzed by per- forming a large number of experiments. The interaction mechanism was interpreted based on: i) retention characteristics of structurally related compounds, ii) retention modeling, iii) quantitative structure reten- tion relationship (QSRR), and iv) molecular docking. Small structural differences of related compounds (e.g., reflected in different lipophilicity and polarity) have been found to affect their different binding to human serum albumin. It was found that drug retention in HSA column can be successfully described by using the quadratic function. The isocratic (logk(14%)) and extrapolated (b0(LSS)) retention factors showed the highest correlation (r > 0.76) with the constant that defines the binding affinity for human serum albumin (ACD/I- Lab). Therefore, selected chromatographic parameters can demonstrate reliable applicability for rapid screening of drug-plasma protein binding in drug discovery. In QSRR study, the resulting SVM/logk(14%) and MLR/b0(LSS) models display high internal and external predictive power. The constitutional properties (double bonds, aromatic rings, benzyl, allyl, -amino and -sulfur containing functional groups) supported by the charged parts of surface area had a significant impact on human serum albumin-binding affinity, which was also confirmed with molecular docking study. The high structural diversity of the data set provides wide applicability of tested chromatographic conditions and constructed models for defining the phar- macokinetic profile and possible structural modifications that can increase plasma protein binding of newly synthesized, pharmaceutically important compounds.

AB  - The human serum albumin (HSA) is well known for its extraordinary binding capacity
for both endogenous and exogenous compounds, including a wide range of drugs. The goal of
our investigation was to evaluate the distribution process for 15 CNS active compounds. The
drug-plasma protein interaction was evaluated under simulative physiological conditions on the
HSA-based stationary phase by using the mixture of Sørensen phosphate buffer (pH 7.40) and
acetonitrile modifier as a mobile phase (84:16 v/v). The retention parameters (k) were used to
approximate the % of protein-binding by calculating the P(%) values. The results obtained
through this study demonstrated that the constitutional properties (e.g. number of total bonds,
atoms, carbon atoms) and lipophilicity have a strong positive impact on the HSA-binding
affinity. The coefficient of diffusion has a negative impact, while the atoms and sites available
for the CYP450 oxidation showed the most significant correlation (r = 0.92). This study
provides a basis for further in vitro chromatographical investigations of drug-HSA interaction
for CNS active compounds. The correlation between obtained retention data and the availability
to enzymes oxidation indicates the application of the tested system in the assessment of the
metabolic degradation profile of CNS related drugs.

AB  - Dopamine is an important neurotransmitter in the human brain and its altered concentrations can lead to various neurological diseases. We studied the binding of novel compounds at the dopamine D2 (D2R) and D3 (D3R) receptor subtypes, which belong to the D2-like receptor family. The synthesis, in silico, and in vitro characterization of 10 dopamine receptor ligands were performed. Novel ligands were docked into the D2R and D3R crystal structures to examine the precise binding mode. A quantum mechanics/molecular mechanics study was performed to gain insights into the nature of the intermolecular interactions between the newly introduced pentafluorosulfanyl (SF5) moiety and D2R and D3R. A radioligand displacement assay determined that all of the ligands showed moderate-to-low nanomolar affinities at D2R and D3R, with a slight preference for D3R, which was confirmed in the in silico studies. N-{4-[4-(2-Methoxyphenyl)piperazin-1-yl]butyl}-4-(pentafluoro-λ6-sulfanyl)benzamide (7i) showed the highest D3R affinity and selectivity (pKi values of 7.14 [D2R] and 8.42 [D3R]).

AB  - The aim of this study was to develop a novel reversed-phase high-performance liquid chromatography (RP-HPLC)
method for efficient separation of ivabradine and its 11 impurities. Similar polarity of impurities in the sample mixture
made method optimization challenging and accomplishable only when different chemometric tools, such as
principal component analysis (PCA), Box–Behnken design (BBD), and desirability function as a multicriteria approach,
were employed. The presence of 3 positional isomers (impurities III, V, and VI), keto–enol tautomerism of
impurity VII, and diastereoisomers of impurity X made separation of this complex mixture even more challenging.
Chromatographic retention parameters obtained with the mobile phase consisting of 30 mM phosphate buffer and
acetonitrile (80:20, v/v) on four different RP-HPLC columns at varying pH values (3.0, 4.0, and 5.0) were subjected
to the PCA analysis to select the column with the most appropriate selectivity. Then the column temperature,
pH of the aqueous component of mobile phase, phosphate buffer molarity and the organic solvent content in the
mobile phase were estimated employing BBD. Valid and reliable mathematical models towards resolution of twelve
critical peak pairs were obtained. After determination of the desirability making criteria for all responses, desirability
functions were established and used in optimization. The proposed optimal chromatographic conditions included
the Zorbax Eclipse Plus C18 chromatographic column (100 × 4.6 mm, 3.5 μm), the column temperature of 34 °C,
the mobile phase flow rate of 1.6 mL min−1 and the UV detection at 220 nm. The mobile phase consisted of the
28 mM phosphate buffer at pH 6.0 and acetonitrile (85:15, v/v). Separation of one pair of positional isomers was
not achieved, so methanol was added to the organic part of mobile phase in small increments with the optimal ratio
of methanol to acetonitrile 59:41, v/v. The overall organic component of the mobile phase also increased to 18%,
accelerating the chromatographic analysis.

AB  - Multi-target compounds are designed to act on at least two targets in synergistic way, in order to produce stronger biological effect. The link
between cancer and inflammation has been intensively studied in last years and inhibition of both COX-2 and 5-LOX enzymes may be an
effective therapeutic approach for colon cancer treatment [1]. Acridines are known as DNA-topoisomerase II inhibitors. These compounds
intercalate into the DNA and inhibit topoisomerase II by their side chain. Recent studies showed additional activities of acridine derivatives,
depending on the side chain structure, such as inhibition of Src, MEK and VEGFR2 kinases [2,3]. Altered activity of PI3K/mTOR signaling pathway
is one of the most common aberrations found in various forms of neoplastic lesions. Dual inhibition of PI3K and mTOR represents a reasonably
attractive concept in potential cancer treatment [4]. In this paper, design of three groups of multi-target compounds with potential anticancer
activity is presented. Designed compounds are potential inhibitors of COX-2 and 5-LOX, DNA-topoisomerase II complex and kinases (Src, MEK
and VEGFR2), as well as dual inhibitors of mTOR and PI3K. A set of 27 compounds with published inhibitory activity on COX-2 and 5-LOX was
formed and two QSAR models, for both activities, were created in Pentacle program. On the basis of models’ interpretation, nine new
compounds were designed and activity on both targets predicted by developed models. Twenty-three acridine derivatives were designed and
their interactions with DNA-topoisomerase II complex, Src, MEK and VEGFR2 were tested using AutoDock Vina program. Nineteen designed
compounds bind to DNA similarly to inhibitor amsacrine and among them, ten derivatives show key binding interactions with tested kinases and
therefore possess potential to inhibit them. A dataset of eighty-five compounds with dual PI3K/mTOR inhibitory activities was formed,
divided into two groups based on their structural analogy and 3D-QSAR analysis of each group was performed in Pentacle program,
9
resulting in four QSAR models. On the basis of these results, new compounds were designed and further evaluated by use of molecular
docking, virtual screening and ADMET predictions. Finally, seven compounds were chosen as the most promising new dual mTOR/PI3K inhibitors.

abstract = "Multi-target compounds are designed to act on at least two targets in synergistic way, in order to produce stronger biological effect. The link
between cancer and inflammation has been intensively studied in last years and inhibition of both COX-2 and 5-LOX enzymes may be an
effective therapeutic approach for colon cancer treatment [1]. Acridines are known as DNA-topoisomerase II inhibitors. These compounds
intercalate into the DNA and inhibit topoisomerase II by their side chain. Recent studies showed additional activities of acridine derivatives,
depending on the side chain structure, such as inhibition of Src, MEK and VEGFR2 kinases [2,3]. Altered activity of PI3K/mTOR signaling pathway
is one of the most common aberrations found in various forms of neoplastic lesions. Dual inhibition of PI3K and mTOR represents a reasonably
attractive concept in potential cancer treatment [4]. In this paper, design of three groups of multi-target compounds with potential anticancer
activity is presented. Designed compounds are potential inhibitors of COX-2 and 5-LOX, DNA-topoisomerase II complex and kinases (Src, MEK
and VEGFR2), as well as dual inhibitors of mTOR and PI3K. A set of 27 compounds with published inhibitory activity on COX-2 and 5-LOX was

AB  - Investigation of the retention behavior of a wide range of analytes (43 nitrogen containing heterocyclic
and guanidine derivatives such, as imidazoline and serotonin receptor ligands, or their related
compounds) was performed on the mixed-mode stationary phase in the combined
reversed-phase (RP) and hydrophilic interaction liquid chromatography (HILIC) modes. The imidazoline
receptor ligands are the imidazoline or guanidine analogues with numerous therapeutic applications
(such, as antihypertensives, diuretics, antiallergenics, antidiabetics, and antipsychotics), while the
serotonin receptor ligands are the piperazine derivatives which exert an effect on positive and negative
symptoms of schizophrenia, mania and mixed states of bipolar disorder.
On the mixed-mode stationary phase, the retention behaviour of investigated compounds
was described as a function of the aqueous eluent volume fractions, φ(aq), and total polarity of mobile
phase (Ptot). The turning point was discussed based on different mobile phase characteristics
representing the shift between the HILIC and the RP chromatographic mode. The influence
of molecular properties on the main retention characteristics (turining point and the extrapolated
retention parameters) is going to be discussed.

AB  - Dopamine receptors are divided into two subclasses: D1 like receptors (D1 and D5 subtypes) and D2 like
receptors (D2, D3 and D4) [1]. Based on a general pharmacophore [2] we introduced the pentafluorosulfanyl
moiety (SF5-) group as an interesting pharmacological tool to investigate D2 like receptors. This moiety
displays high electronegativity and lipophilicity, while being thermally stable [3] and more resistant to
hydrolysis in comparison to that of other polyfuorinated moieties (e.g. CF3 or OCF3). Four novel compounds
with SF5 substituent have been synthesized, in silico and in vitro tested in order to examine their affinity
and selectivity towards human dopamine D2 and D3 receptor subtypes. All compounds showed high affinity
in the nanomolar concentration ranges at both receptors with ST 2200 expressing highest selectivity. In
silico examination determined high values of coefficient of determination (R2) and Spearman correlation
coefficient revealed good correlation between in silico parameters and experimentally obtained Ki values.
These results show that pentafluorosulfanyl substituent is a highly suitable moiety for structural variations
that has to be further investigated and could serve as novel substituent in numerous compound classes.

AB  - The retention behavior of ivabradine, its 11 related compounds, diltiazem and verapamil has been examined by thin-layer chromatography using non-polar stationary phase (RP-18) and the following mobile phases: methanol-6.25% aqueous ammonia, tetrahydrofuran - 6.25% aqueous ammonia, and also polar stationary phase (silica gel) with tetrahydrofuran - 6.25% methanolic ammonia as mobile phase. In the examined chromatographic systems, linear relationships were established between the retention coefficients, R-M(0) and m, and molecular properties of the investigated antiarrhythmic drugs. The Quantitative Structure Retention Relationship (QSRR) modeling was performed with use of the stepwise multiple linear regression, in order to select the most important molecular properties which influence the retention behavior. The developed models revealed that apart from lipophilicity also the molecular volume (V), and the hydrogen bond basicity (B) of the tested compounds are the most important for the retention behavior in the examined chromatographic systems.

Suitability of the linear retention modelling in the HILIC and RP modes was tested including separate contributions from adsorption and partition. For the HILIC retention, the partition model was found to provide better description compared with the adsorption model. In a wider range of the aqueous eluent volume fractions, phi(aq), retention was described as a function of volume fractions and total polarity of mobile phase using the mixed-mode retention modelling. The obtained results revealed that the shift of the chromatographic mode can be calculated from the change of total polarity of mobile phase in a multimodal relation, logarithm of retention factor vs. total polarity, with the minimum value representing the turning point between the HILIC and the RP mode. Molecular properties of the investigated compounds that influence the retention behavior and the turning point were selected using Multiple Linear Regression (MLR) and Support Vector Machine (SVM). Slightly better statistical results were found for the logk(w)(RP)(aq)/MLR, logk(w)(HILIC) (org)/MLR, logk(b)(HILIC)(aq)/MLR, and phi(min) (aq)/SVM (RBF) QSRR models than for the logk(w)(RP)(aq)/SVM, logk(w)(NILIC)(org)/SVM, logk(b)(HILIC)(aq)/SVM. and phi(min)(aq)/MLR modelling. With this insight, it is possible to precisely define and predict the retention characteristics based on physicochemical properties of imidazoline and piperazine related compounds.

AB  - Retention mechanism in the hydrophilic interaction liquid chromatography
(HILIC) mode is complex and still a subject of many controversial
interpretations. In order to describe the HILIC retention mechanism, different
retention models can be employed. In this study, we investigated the partition
mechanism for 7 imidazoline receptor ligands on the mixed mode HILIC
stationary phase. Applicability of the assumed retention model in description
of the HILIC retention behavior of the compounds was successfully
demonstrated.
