Cysteinyl leukotrienes 1 (CysLT1) receptor is a promising drug target for rhinitis or other allergic diseases. In our study, we built classification models to predict bioactivities of CysLT1 receptor antagonists. We built a dataset with 503 CysLT1 receptor antagonists which were divided into two groups: highly active molecules (IC50 < 1000 nM) and weakly active molecules (IC50 >= 1000 nM). The molecules were characterized by several descriptors including CORINA descriptors, MACCS fingerprints, Morgan fingerprint and molecular SMILES. For CORINA descriptors and two types of fingerprints, we used the random forests (RF) and deep neural networks (DNN) to build models. For molecular SMILES, we used recurrent neural networks (RNN) with the self-attention to build models. The accuracies of test sets for all models reached 85%, and the accuracy of the best model (Model 2C) was 93%. In addition, we made structure-activity relationship (SAR) analyses on CysLT1 receptor antagonists, which were based on the output from the random forest models and RNN model. It was found that highly active antagonists usually contained the common substructures such as tetrazoles, indoles and quinolines. These substructures may improve the bioactivity of the CysLT1 receptor antagonists. [GRAPHICS] .

Nicotinic acetylcholine receptor alpha 3 beta 4 is considered as a potential target for anti-smoking drug discovery. In this study, in-silico approaches, including molecular docking and molecular dynamics simulation were applied to investigate binding affinities of 300 alkaloids into the alpha 3 beta 4(Pdb id: 6PV8). The docking results showed that most of the alkaloids fitted well into the binding pocket of alpha 3 beta 4. The top hit compounds were A122 (indole alkaloid) and A128 (tropane alkaloid) with their binding affinities of less than -8.0 kcal.mol(-1) and the interactions with key residue, Trp149. Structures and binding affinities relationships between the indole and tropane compounds with the alpha 3 beta 4 emphasized the important roles of indole backbone and the benzyl substituent at C3 of tropane scaffold in forming the hydrophobic interactions making good binding affinities. Molecular dynamics simulations revealed the potential of A128 to binding stably with the alpha 3 beta 4 during 20 ns. Binding free energy of the complex A128 – alpha 3 beta 4 was calculated based on Molecular Mechanics – Poisson Boltzmann Surface Area (MM-PBSA) method, which also emphasized the importance of electrostatic contacts over van der Waals interactions for proper binding. Hence, A128 can be additionally explored by in-vitro and in-vivo experiments for further confirmation of its smoking cessation treatment.

Over the last decade, there has been substantial interest in the use of melatonin (MLT) and MLT-like compounds in the treatment of several diseases. MLT can scavenge different reactive oxygen species and can also stimulate the synthesis of antioxidant enzymes. Our ongoing study relies on changing the groups in the different modifiable sites of the indole ring to increase the antioxidant activity. In this study a new approach for substitution of indole ring as indole based MLT analogue was proposed. We report the synthesis and characterization of a series of new indole-7-aldehyde hy-drazide/hydrazone derivatives as indole-based MLT analogues. Anticancer potential of the compounds were evaluated both by their antioxidant and CYP1 inhibitory activities. In vitro antioxidant capacity of the compounds was investigated both in a cell-based (DCFH assay) and a cell-free (DPPH assay) assay. Potential inhibitory effects of the compounds on CYP1 catalytic activity were investigated via EROD assay. Cytotoxic activity of the compounds was further evaluated by the MTT assay in CHO-K1 cells. MLT analogues having an o halogenated aromatic moiety exhibited effective antioxidant properties without having any cytotoxic effect. In conclusion, MLT derivatives represent promising scaffolds for discovery of effective antioxidant agents.

Cancer continues to be the second leading cause of death worldwide. Discovery of novel therapeutic agents has crucial importance for improvement of our medical management capabilities. Dysregulation of the MET receptor tyrosine kinase pathway plays an important role in cancer progression, making this receptor an attractive molecular target for anticancer drug discovery. In this study, twenty-seven 3,4-dihydropyrimidin-2(1H)-one C5 amide derivatives were synthesized and their cancer cell growth inhibitory activity was examined against MCF-7, HT-29 and MOLT-4 cells and also NIH/3T3 non-cancer cells by MTT assay. The antipmliferative effect of the most potent derivatives were tested against MET-dependent EBC-1 and MKN-45, lung and gastric cancer cell lines, respectively. MET kinase inhibition was measured by a Homogenous Time Resolved Fluorescence (HTRF) Assay. The influence of the test compounds on cell cycle was examined by RNase/PI flow cytometric assay. A number of compounds exhibited considerable antiproliferative effects against breast and colon cancer and leukemia cell lines, relatively sparing non-cancer cells. Some derivatives bearing benzothiazolyl carboxamide moiety at C5 position (15, 21, 23, 31, and 37) showed the highest activities with IC50 values as low as 10.9 mu M. These compounds showed antiproliferative effects also against MET-amplified cells and dose-dependently inhibited MET kinase activity. They also induced G0/G1 cell cycle arrest at lower doses and apoptosis at higher doses. Molecular docking and dynamics simulation studies confirmed the interaction of compound 23 with the active site of the MET receptor. These findings demonstrate that 3,4-dihydropyrimidin-2(1H)-one analogues may represent promising targeted anticancer agents.

alpha-Methylene-delta-valerolactone (MVL) is a bifunctional monomer comprising of a highly stable six-membered delta-valerolactone ring and highly reactive C(sic)C bond. Previously, the vinyl-addition polymerization (VAP) product, namely P(MVL)(VAP), has been formed exclusively. In this study, this conventional chemoselectivity is reversed, wherein organic catalysts are used to enable the first ring-opening polymerization (ROP) of MVL, exclusively affording a metal-free, unsaturated polyester, namely P(MVL)(ROP). This challenging goal is achieved by investigating different catalysts, initiators, and reaction conditions. In addition, the formation of two polymers, namely P(MVL)(ROP) and P(MVL)(VAP), is easily regulated by varying the polymerization solvent. The resulting P(MVL)(ROP) can be easily post-functionalized to form crosslinked or sulfurized materials; notably, it can be almost completely converted into its monomer thermochemically.
