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.

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  - Considering the urgent need for novel therapeutics in ongoing COVID-19 pandemic, drug repurposing approach might offer rapid solutions comparing to de novo drug design. In this study, we designed an integrative in silico drug repurposing approach for rapid selection of potential candidates against SARS-CoV-2 Main Protease (Mpro). To screen FDA-approved drugs, we implemented structure-based molecular modelling techniques, physiologically-based pharmacokinetic (PBPK) modelling of drugs disposition and data mining analysis of drug-gene-COVID-19 association. Through presented approach, we selected the most promising FDA approved drugs for further COVID-19 drug development campaigns and analysed them in context of available experimental data. To the best of our knowledge, this is unique in silico study which integrates structure-based molecular modeling of Mpro inhibitors with predictions of their tissue disposition, drug-gene-COVID-19 associations and prediction of pleiotropic effects of selected candidates.

AB  - Histone methyltransferase DOT1L catalyzes mono-, di-and trimethylation of histone 3 at lysine residue 79 (H3K79) and hypermethylation of H3K79 has been linked to the development of acute leukemias characterized by the MLL (mixed-lineage leukemia) rearrangements (MLLr cells). The inhibition of H3K79 methylation inhibits MLLr cells proliferation, and an inhibitor specific for DOT1L, pinometostat, was in clinical trials (Phase Ib/II). However, the compound showed poor pharmacological properties. Thus, there is a need to find new potent inhibitors of DOT1L for the treatment of rearranged leukemias. Here we present the design, synthesis, and biological evaluation of a small molecule that inhibits in the nM level the enzymatic activity of hDOT1L, H3K79 methylation in MLLr cells with comparable potency to pinometostat, associated with improved metabolic stability and a characteristic cytostatic effect.

Imidazolines: In silico off-target fishing in the class A of G protein-coupled receptors

AB  - Centrally acting hypotensive imidazoline derivatives are agonists of α2-adrenoceptors and non-adrenergic
I1-imidazoline receptors. Based on the finding that a central antihypertensive agent with high affinity for
I1-type imidazoline receptors – rilmenidine, shows cytotoxic effects on cultured cancer cell lines, it has been
suggested that imidazoline receptors agonists might have a therapeutic potential in cancer therapy. Never-
theless, rilmenidine itself does not represent a suitable candidate because of possible side effect caused by
activation of α 2 -adrenergic receptors. In our previous work, several novel rilmenidine-derived compounds
with anticancer potential and without an agonistic activity on α 2
-adrenoceptor were identified. Taking into
consideration that human α2
-adrenergic receptors belong to the rhodopsin-like class A of G protein-coupled
receptors (GPCRs), the biggest group of drug targets, that share structure similarity, it is reasonable to assume
that these ligands might have the affinity on some other receptors from the same class.
To investigate potential additional targets for novel imidazoline I1 agonists a reverse docking protocol on
107 GPCRs, using 63 imidazoline ligands and their 670 decoys was prepared. Unlike typical molecular dock-
ing protocol, where series of small molecules are docked in one macromolecular target, in case of reverse
docking a small-molecule is docked in the set of potential target proteins. Due to the availability of crystal
structures all of the included GPCRs, were in inactive state, and therefore suitable for identification of the
receptors antagonized by imidazoline ligands. Based on ROC curves and Enrichment Factors, 20 potential
off-target GPCRs were selected. To better assess the affinity of imidazoline derivatives for chosen receptors,
an additional docking study was performed, and docking scores of imidazolines were compared with docking
scores of known antagonists. Finally, to verify in silico results, three ligands with high scores and tree ligands
with low scores were tested for antagonistic activity on α2
-adrenergic receptors.
The protocol described here could be applied on all the small molecules, for the detection of potential inter-
actions with GPCRs of class A, in the early stage of drug design process. Additionally, this protocol is easily
expandable, by adding novel receptors/subfamily of receptors as soon as the crystal structures and/or 3D
models become available.

abstract = "Centrally acting hypotensive imidazoline derivatives are agonists of α2-adrenoceptors and non-adrenergic
I1-imidazoline receptors. Based on the finding that a central antihypertensive agent with high affinity for
I1-type imidazoline receptors – rilmenidine, shows cytotoxic effects on cultured cancer cell lines, it has been
suggested that imidazoline receptors agonists might have a therapeutic potential in cancer therapy. Never-
theless, rilmenidine itself does not represent a suitable candidate because of possible side effect caused by
activation of α 2 -adrenergic receptors. In our previous work, several novel rilmenidine-derived compounds
with anticancer potential and without an agonistic activity on α 2
-adrenoceptor were identified. Taking into
consideration that human α2
-adrenergic receptors belong to the rhodopsin-like class A of G protein-coupled
receptors (GPCRs), the biggest group of drug targets, that share structure similarity, it is reasonable to assume
that these ligands might have the affinity on some other receptors from the same class.
To investigate potential additional targets for novel imidazoline I1 agonists a reverse docking protocol on
107 GPCRs, using 63 imidazoline ligands and their 670 decoys was prepared. Unlike typical molecular dock-
ing protocol, where series of small molecules are docked in one macromolecular target, in case of reverse
docking a small-molecule is docked in the set of potential target proteins. Due to the availability of crystal
structures all of the included GPCRs, were in inactive state, and therefore suitable for identification of the
receptors antagonized by imidazoline ligands. Based on ROC curves and Enrichment Factors, 20 potential
off-target GPCRs were selected. To better assess the affinity of imidazoline derivatives for chosen receptors,
an additional docking study was performed, and docking scores of imidazolines were compared with docking
scores of known antagonists. Finally, to verify in silico results, three ligands with high scores and tree ligands
with low scores were tested for antagonistic activity on α2
-adrenergic receptors.

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  - Based on the finding that a central antihypertensive agent with high affinity for I1-type imidazoline receptors – rilmenidine, shows cytotoxic effects on cultured cancer cell lines, it has been suggested that imidazoline receptors agonists might have a therapeutic potential in the cancer therapy. Nevertheless, potential rilmenidine side effects caused by activation of α-adrenoceptors, or other associated receptors and enzymes, might hinder its therapeutic benefits. Considering that human α-adrenoceptors belong to the rhodopsin-like class A of G-protein-coupled receptors (GPCRs) it is reasonable to assume that imidazolines might have the affinity for other receptors from the same class. Therefore, to investigate possible off-target effects of imidazoline ligands we have prepared a reverse docking protocol on class A GPCRs, using imidazoline ligands and their decoys. To verify our in silico results, three ligands with high scores and three ligands with low scores were tested for antagonistic activity on α2- adrenoceptors.

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  - Abnormally folded alpha-synuclein protein, dysfunctional mitochondria, increased oxidative stress and reduced dopamine
neurotransmitter synthesis are a
ll extremely well characterized phenomena in Parkinson’s disease (PD) and are thought to be interconnected. While direct
targeting of these areas has demonstrated neuroprotection in vitro and in vivo, there has been a major lack of success in clinical
trials. A critical component in the failure of these clinical trials is the inability to specifically target drugs to dopamine producing
neurons in the brain.
New drugs targeting the dopaminergic neurons by specific uptake through the human dopamine transporter (hDAT) could
represent a viable strategy for establishing selective neuroprotection. Molecules able to increase the bioactive amount of
extracellular dopamine, thereby enhancing and compensating a loss of dopaminergic neurotransmission, and to exert
neuroprotective response because of their accumulation in the cytoplasm, are required.
By means of homology modeling, molecular docking and molecular dynamics simulations, we have generated 3D structure
models of hDAT in complex with substrate and inhibitors. Our results clearly reveal differences in binding kinetics of these
compounds to the hDAT in the open and closed conformations, critical for future drug design. The established in silico
approach allowed the identification of three promising substrate compounds that were subsequently analyzed for their
efficiency in inhibiting hDAT-dependent fluorescent substrate uptake, through in vitro live cell imaging experiments. Taken
together, our work presents the first implementation of a combined in silico/in vitro-approach enabling the selection of
promising dopaminergic neuron specific substrates.

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.
