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  - The drug-human serum albumin binding interaction was evaluated on a stationary phase immobilized with human serum albumin using a mixture of phosphate buffer (pH 7.0) and acetonitrile modifier as mobile phase. 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.

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  - Permeability assessment of small molecules through the blood-brain barrier (BBB) plays a significant role in the development of effective central nervous system (CNS) drug candidates. Since in vivo methods for BBB permeability estimation require a lot of time and resources, in silico and in vitro approaches are becoming increasingly popular nowadays for faster and more economical predictions in early phases of drug discovery. In this work, through application of in vitro parallel artificial membrane permeability assay (PAMPA-BBB) and in silico computational methods we aimed to examine the passive permeability of eighteen compounds, which affect serotonin and dopamine levels in the CNS. The data set was consisted of novel six human dopamine transporter (hDAT) substrates that were previously identified as the most promising lead compounds for further optimisation to achieve neuroprotective effect, twelve approved CNS drugs, and their related compounds. Firstly, PAMPA methods was used to experimentally determine effective BBB permeability (Pe) for all studied compounds and obtained results were further submitted for quantitative structure permeability relationship (QSPR) analysis. QSPR models were built by using three different statistical methods: stepwise multiple linear regression (MLR), partial least square (PLS), and support-vector machine (SVM), while their predictive capability was tested through internal and external validation. Obtained statistical parameters (MLR- R2pred=-0.10; PLS- R2pred=0.64, r2m=0.69, r/2m=0.44; SVM- R2pred=0.57, r2m=0.72, r/2m=0.55) indicated that the SVM model is superior over others. The most important molecular descriptors (H0p and SolvEMt_3D) were identified and used to propose structural modifications of the examined compounds in order to improve their BBB permeability. Moreover, steered molecular dynamics (SMD) simulation was employed to comprehensively investigate the permeability pathway of compounds through a lipid bilayer. Taken together, the created QSPR model could be used as a reliable and fast pre-screening tool for BBB permeability prediction of structurally related CNS compounds, while performed MD simulations provide a good foundation for future in silico examination.

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  - Drug discovery and development is a very challenging, expensive and time-consuming
process. Impressive technological advances in computer sciences and molecular biology have
made it possible to use computer-aided drug design (CADD) methods in various stages of the
drug discovery and development pipeline. Nowadays, CADD presents an efficacious and
indispensable tool, widely used in medicinal chemistry, to lead rational drug design and synthesis
of novel compounds. In this article, an overview of commonly used CADD approaches from hit
identification to lead optimization was presented. Moreover, different aspects of design of multitarget ligands for neuropsychiatric and anti-inflammatory diseases were summarized. Apparently,
designing multi-target directed ligands for treatment of various complex diseases may offer better
efficacy, and fewer side effects. Antipsychotics that act through aminergic G protein-coupled
receptors (GPCRs), especially dopamine D2 and serotonin 5-HT2A receptors, are the best option
for treatment of various symptoms associated with neuropsychiatric disorders. Furthermore,
multi-target directed cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) inhibitors are also
a successful approach to aid the discovery of new anti-inflammatory drugs with fewer side effects.
Overall, employing CADD approaches in the process of rational drug design provides a great
opportunity for future development, allowing rapid identification of compounds with the optimal
polypharmacological profile.

AB  - Serotonin 5-HT2A receptors (5-HT2AR) are highly expressed in human prefrontal cortex, essential for
learning and cognition [1]. Consequently, antagonists of these receptors are effective in treatment of
various neuropsychiatric disorders, such as depression, insomnia, schizophrenia, anxiety, and
cent progress in molecular modelling studies has led to significant success
in drug discovery using ligand and target-based methods. To design novel potent 5-HT2AR antagonists,
we report a strategy of combining three-dimensional quantitative structure-activity relationship (3DQSAR)
modelling with molecular docking and molecular dynamic (MD) simulation. Based on the
common structural features, data set of 75 compounds was divided into three clusters. Firstly, MD
simulations were carried out for each cluster representative in complex with 5-HT2AR, providing
important molecular level insight into their structure and dynamics. Afterward, to provide more
accurate information about binding modes in the active site of the receptor, obtained conformations
were used for docking studies and generation of the virtually bioactive conformations of all studied
ligands. In addition, 3D-QSAR study, utilizing selected conformers, was carried out to gain further
insights into the structural requirements that affect their antagonistic activity. Besides, some
commercially available 5-HT2AR antagonists were examined through in vitro PAMPA essay, as well as
in silico computational methods not only to improve BBB permeability of new designed compounds,
but also to establish promising tool to study their membrane permeability in detail. Overall, these and
future results will provide new methodologies that could be used as guidelines for rational drug design
of novel 5-HT2AR antagonists.

AB  - Imidazoline I2 receptors (I2-IR), widely distributed in the CNS and altered in patients that suffer from neurodegenerative disorders, are orphans from a structural point of view, and new I2-IR ligands are urgently required for improving their pharmacological characterization. We report the synthesis and three-dimensional quantitative structure-activity relationship (3D-QSAR) studies of a new family of bicyclic α-iminophosphonates endowed with relevant affinities for human brain I2-IR. Acute treatment in mice with a selected compound significantly decreased Fas-associated protein with death domain (FADD) in the hippocampus, a key signaling mediator of neuroprotective actions. Additionally, in vivo studies in the familial Alzheimer's disease 5xFAD murine model revealed beneficial effects in behavior and cognition. These results are supported by changes in molecular pathways related to cognitive decline and Alzheimer's disease. Therefore, bicyclic α-iminophosphonates are tools that may open new therapeutic avenues for I2-IR, particularly for unmet neurodegenerative conditions.

AB  - The serotonin 5-HT2A receptors are widely distributed throughout the central and the peripheral nervous system where they
play a key role in many physiological functions. Abnormal activity of 5-HT2A receptors is associated with various neurological
disorders, such as depression, schizophrenia, anxiety, and Parkinson disease. In order to analyze 3D-structure of the pharmacophore as well as binding kinetics of 5-HT2A-R antagonists, we have combined ligand and structure based approaches.
Three-dimensional quantitative structure-activity relationship (3D-QSAR) study in combination with molecular docking and
molecular dynamic (MD) simulation was used to identify key substituents responsible for high binding affinity and selectivity of
5-HT2A antagonists. The study was performed on wide range of structurally diverse antagonists that were divided into three
different clusters: clozapine, ziprasidone, and CHEMBL240876 derivates. We have obtained three different inactive, antagonistbound,
conformations of this receptor by using the 50ns long MD simulations with each cluster representative. Subsequently,
these conformations were used as templates for docking studies in order to find virtually bioactive conformations of ligands.
Selected virtually bioactive conformations were used for calculation of specific molecular descriptors (Grid Independent
Descriptors- GRIND) and 3D-QSAR model building. The 3D-QSAR approach was used to select the most influential variables
which were used for clarifying the structural features required for 5-HT2A antagonists. The reliability and predictive power of the
model was assessed using an external test set compounds and showed reasonable external predictability. The study provides
valuable information about the key structural features that are required in the rational drug design of novel 5-HT2A antagonists.

AB  - Serotonin 5-HT2A receptors are widely distributed in the human brain where they play a key role in
many physiological functions. Numerous neurological disorders caused by 5-HT2A malfunction have
made it a very attractive target. Therefore, analysis of 3D-structure of the pharmacophore as well as
binding kinetics of 5-HT2A antagonists would be beneficial for future rational drug design. Three dimensional quantitative structure-activity relationship (3D-QSAR) study was combined with molecular docking and molecular dynamic (MD) simulation in order to find crucial structural features responsible for high binding affinity and selectivity of 5-HT2A antagonists. This study was performed on wide range of structurally diverse antagonists that were divided into three different clusters: clozapine, ziprasidone, and CHEMBL240876 derivates. We have used 50ns MD simulations to obtain inactive, antagonist bound, conformations of each cluster representative. Subsequently, these conformations were used as templates for docking studies in order to find virtually bioactive conformations of examined compounds.
Selected virtually bioactive conformations were used for generation of specific molecular descriptors
(Grid Independent Descriptors- GRIND) and 3D-QSAR model building. The 3D-QSAR approach was used to identify the most important structural determinants responsible for the antagonistic activity and to propose structural modifications for novel antagonists of serotonin 5-HT2A receptors. Furthermore, diverse internal and external validation methods were applied. Obtained statistical parameters indicated the reliability and good predictive potential of the created model. Following these findings we have identified differences and similarities in the binding mode and pharmacophores of structurally diverse 5-HT2A antagonists as well as conformational changes they provoke.

AB  - 2-Imidazoline-containing compounds constitute a valuable class of agents that modulate α2-
adrenergic receptors and often show a high affinity for imidazoline I2-receptors (I2-IR). Moreover, 2-
imidazolines are an important class of heterocyclic scaffolds found in natural product chemistry,
coordination chemistry, and homogeneous catalysis. To meet the demand for 2-imidazolinecontaining
compounds, different synthetic approximations were developed. In this work, we
describe an efficient and user-friendly synthetic process involving the combination of isocyanidebased
multicomponent reaction and microwave heating without the need of anhydrous atmosphere
or additional solvents that generates unprecedented (2-imidazolin-4-yl)phosphonates [1].
We assessed the pharmacological profile and selectivity of the prepared compounds upon I2-IR.
Owing to the outstanding high I2-IR affinity of one of the prepared compounds and high selectivity
devoid to the α2-adrenoceptor of other compounds, markedly better than any described I2-IR ligand
to date, (2-imidazolin-4-yl)phosphonates might be considered as a suitable scaffold for designing
novel I2-IR ligands [2]. In addition, we demonstrated the effectiveness of two of the new I2-IR ligands
in an in vivo female model for cognitive decline (SAMP8), and we analyzed the pathological
biomarkers for neurodegeneration. This study is the first experimental evidence that demonstrates
the possibility of using this receptor as a target for cognitive impairment [3].
Note, theoretical studies were carried out for designing compounds with enhanced activity and
selectivity upon I2-IR based on created 3D-QSAR model.
In this work, green chemistry to access an unprecedented scaffold and promising pharmacological
results in the neurodegeneration field walked together.

abstract = "2-Imidazoline-containing compounds constitute a valuable class of agents that modulate α2-
adrenergic receptors and often show a high affinity for imidazoline I2-receptors (I2-IR). Moreover, 2-
imidazolines are an important class of heterocyclic scaffolds found in natural product chemistry,
coordination chemistry, and homogeneous catalysis. To meet the demand for 2-imidazolinecontaining
compounds, different synthetic approximations were developed. In this work, we
describe an efficient and user-friendly synthetic process involving the combination of isocyanidebased
multicomponent reaction and microwave heating without the need of anhydrous atmosphere
or additional solvents that generates unprecedented (2-imidazolin-4-yl)phosphonates [1].
We assessed the pharmacological profile and selectivity of the prepared compounds upon I2-IR.
Owing to the outstanding high I2-IR affinity of one of the prepared compounds and high selectivity
devoid to the α2-adrenoceptor of other compounds, markedly better than any described I2-IR ligand
to date, (2-imidazolin-4-yl)phosphonates might be considered as a suitable scaffold for designing
novel I2-IR ligands [2]. In addition, we demonstrated the effectiveness of two of the new I2-IR ligands
in an in vivo female model for cognitive decline (SAMP8), and we analyzed the pathological
biomarkers for neurodegeneration. This study is the first experimental evidence that demonstrates
the possibility of using this receptor as a target for cognitive impairment [3].
Note, theoretical studies were carried out for designing compounds with enhanced activity and
selectivity upon I2-IR based on created 3D-QSAR model.
In this work, green chemistry to access an unprecedented scaffold and promising pharmacological
results in the neurodegeneration field walked together.",

AB  - Serotoninski 5‐HT2A receptori su uključeni u mnogobrojne fiziološke i
patofiziološke procese. Strukturno različiti ligandi (agonisti, antagonisti i inverzni
agonisti) dovode do različitih konformacionih promena ovih receptora, izazivajući
brojne biološke odgovore.
Da bi se molekul ponašao kao agonista/antagonista potrebno je da poseduje
različite funkcionalne grupe i specifične interakcije sa određenim aminokiselinama u
vezujućem mestu receptora. Razumevanje i objašnjavanje različitosti u strukturi i
vezivanju za receptor, kod agonista i antagonista, može biti od značaja za racionalni
dizajn novih lekova.
Za razumevanje strukturnih razlika u farmakoforama, kao i kinetici vezivanja i
zmeđu agonista i antagonista korišćeni su ligand‐based i structure‐based pristupi. 3DQSAR
(3D‐quantitative structure activity relationship) studije su izvođene na grupama
od 79 agonista i 90 antagonista. Uporedo su odrađene četiri simulacije molekularne
dinamike: serotoninski 5‐HT2A receptor u kompleksu sa agonistima (serotonin,
lorkaserin) i antagonistima (klozapin, ziprazidon).
Dobijeni statistički i validacioni parametri za modele agonista i antagonista
ukazuju na pouzdanost i dobru predviđajuću moć 3D‐QSAR modela. Najznačajnije
varijable formiranih modela daju nam uvid u najvažnije strukturne razlike između njih.
Rezultati MD simulacije otkrivaju najvažnije razlike u konformacionim promenama
uzrokovane vezivanjem agoniste/antagoniste, kao i interakcije liganada sa ključnim
aminokiselinama, odgovornim za vezivanje. Pomoću trajektorije iz MD simulacije
izvučeni su modeli, 3D strukture 5‐HT2A receptora u njegovom aktivnom (agonistvezujućem)
i inaktivnom (antagonist‐vezujućem) stanju.
Na osnovu ovih in silico rezultata moguće je zaključiti da li je jedinjenje agonista
ili antagonista. Formirani modeli će dalje biti korišćeni za ligand‐based i structure‐based
virtualni skrining i racionalni dizajn novih 5‐HT2A liganada.
AB  - The serotonin 5‐HT2A receptors have shown a wide range of clinical implications
since they are involved in various physiological and pathophysiological processes.
Structurally diverse ligands (agonists, antagonists, and inverse agonists) can lead to
different biological responses, by provoking different conformational changes of these
receptors.
To behave like an agonist/antagonist the molecule should have a set of
functional groups and specific interactions with certain amino acids in the binding site.
Understanding and explaining dissimilarities in agonist/antagonist structure and
receptor binding would be beneficial for future rational drug design.
To understand structural differences in pharmacophores as well as the binding
kinetics of agonists and antagonists, we have combined ligand‐based and structurebased
approaches. 3D‐quantitative structure‐activity relationship (3D‐QSAR) studies
were performed on a series of 79 agonists and 90 antagonists. Simultaneously, we run
four molecular dynamics (MD) simulations: 5‐HT2A in complex with agonists (serotonin,
lorcaserin), and antagonists (clozapine and ziprasidone).
Obtained statistical and validation parameters for agonists and antagonists
model indicated the reliability and good predictive potential of the 3D‐QSAR models.
The most influential variables of selected models gave us the insight into major
structural dissimilarities between them. Results of MD simulation revealed major
differences in conformational changes caused by agonist/antagonist binding, as well as
ligand interactions with the key amino acids, responsible for them. Additionally, from
MD simulation trajectory, we have extracted 3D structure models of 5‐HT2A in its active
(agonist‐bound) and inactive (antagonist‐bound) state.
Using these finding we will be able to discriminate whether a compound is
agonist or antagonist, in silico. Furthermore, models that we have generated will be
further used for ligand‐based and structure‐based virtual screening and rational drug
design of novel 5‐HT2A ligands.

AB  - All tested compounds show agonistic activity onserotonin5-HT2areceptors, which activation causes neuronal excitations, behavioral changes and platelet aggregation. The main aims of this study were to create 3D-QSAR(3D-Quantitative structure-activity relationship)model, analyse 3D-structure of the pharmacophore, validate the 3D-QSARmodel, and propose structural modification for novel 5-HT2aagonists.3D-QSAR modeling was applied to 51 agonists of 5-HT2areceptors. Dominant forms at physiologic pHof the examined compounds were optimized using the PM3 method and used for QSAR modeling. Data set was divided in two groups, training set of38 compounds, and test set of 13 compounds. Training set was used to build 3D-QSAR model, while test set was examined for the model validation. PLS (Partial Least Square Regression)method was used to develop 3D-QSAR model. Statistical parameters of the created and validated 3D-QSAR model,R2= 0.93, Q2=0.72, RMSEE=0.178, RMSEP=0.190 and R2 pred=0.63, indicate good prognostic capacity of the model.The3D-QSAR model was applied to analyse pharmacophore and to predict activity of other agonists of serotonin 5-HT2areceptors. Information obtained from the 3D-QSAR study indicated that presence of hydrogen bond donor and steric hot spot at a distance 14.80-15.20Å (v477:O-TIP), hydrophobic region and hydrogen bond donor at a distance of 2.40-2.86Å (v226:DRY-O), hydrogen bond donor and hydrogen bond acceptor at a distance of 1.60-2.00Å (v389:O-N1) and two hydrophobic regions at a distance 9.20-9.60Å (v23:DRY-DRY) are essential for agonistic activity on 5-HT2aserotonin receptors.
AB  - Ispitivana jedinjenja djeluju kao agonisti serotoninskih 5-HT2areceptora, i dovode do neuralne ekscitacije, promjene ponašanja i agregacije trombocita. Cilj ove studije je bio formiranje 3D-QSAR (3D-Quantitative structure-activity relationship) modela i 3D-strukture farmakofore agonista serotoninskih 5-HT2a receptora, validacija formiranog 3D-QSAR modela i definisanje strukturnih modifikacija za dizajn novih agonista serotoninskih 5-HT2areceptora. Iz literature su preuzete strukture i aktivnosti 51 agoniste 5-HT2areceptora. Definisani su dominantni oblici ispitivanih jedinjenja pri fiziološkom pH i optimizovane njihove konformacije primjenom PM3 (Parameterized Model revision 3) metode. Ispitivana jedinjenja su podijeljena u dvije grupe, trening set sa 38 jedinjenja i test set sa 13 jedinjenja. Trening set je korišćen za formiranje jednačine i građenje 3D-QSAR modela, a test set za validaciju 3DQSAR modela. Pomoću PLS (Partial Least Square Regression) metode kreira se novi 3DQSAR model i računaju statistički parametri modela: R2=0,93, Q2=0,72, RMSEE=0,178, RMSEP=0,190 i R2pred=0,63. Formirani i validirani 3D-QSAR model je dalje upotrijebljen za analizu 3D-strukture farmakofore i za predviđanje aktivnosti novih agonista serotoninskih 5-HT2areceptora. Analizom je utvrđeno da je za ispoljavanje agonističke aktivnosti na nivou 5-HT2a serotoninskih receptora neophodno prisustvo donora vodonične veze i sternog centra na rastojanju 14,80-15,20Å (v477:O-TIP), donora i akceptora vodonične veze na rastojanju 1,60- 2,00Å (v389:O-N1), hidrofobnog centra i donora vodonične veze na rastojanju 2,40-2,86Å (v226:DRY-O) i dva hidrofobna centra na rastojanju 9,20-9,60Å (v23:DRY-DRY).
