Design, synthesis and anticancer properties of IsoCombretaQuinolines as potent tubulin assembly inhibitors

The synthesis and evaluation of a new series of IsoCombretaQuinolines (IsoCoQuines) 2 with a 2-substituted-quinoline in place of the 3,4,5-trimethoxyphenyl ring present in isoCA-4 and CA-4 are described. Most of these compounds displayed a potent cytotoxic activity (IC50< 10 nM) against a panel of five human cancer cell lines and inhibited tubulin assembly at a micromolar level. The most potent analogue 2b, having a 3-hydroxy-4-methoxyphenyl as B-ring, led to cell cycle arrest in G2/M phase. Docking studies indicate that 2b showed a binding mode comparable to those previously observed with quinazoline analogous (IsoCoQ) and with isoCA-4 at the colchicine binding site of tubulin. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. name: 4-(4-((2,4-Dioxothiazolidin-5-ylidene)methyl)-2-methoxyphenoxy)-3-(trifluoromethyl)benzonitrile, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1055361-35-7, in my other articles.

Identification and molecular modeling of new quinolin-2-one thiosemicarbazide scaffold with antimicrobial urease inhibitory activity

Abstract: A new series of 6-substituted quinolin-2-one thiosemicarbazides 6a?j has been synthesized. The structure of the target compounds was proved by different spectroscopic and elemental analyses. All the designed final compounds were evaluated for their in vitro activity against the urease-producing R. mucilaginosa and Proteus mirabilis bacteria as fungal and bacterial pathogens, respectively. Moreover, all compounds were in vitro tested as potential urease inhibitors using the cup-plate diffusion method. Compounds 6a and 6b were the most active with (IC50 = 0.58 ± 0.15 and 0.43 ± 0.09 muM), respectively, in comparison with lead compound I (IC50 = 1.13 ± 0.00 muM). Also, the designed compounds were docked into urease proteins (ID: 3LA4 and ID: 4UBP) using Open Eye software to understand correctly about ligand?receptor interactions. The docking results revealed that the designed compounds can interact with the active site of the enzyme through multiple strong hydrogen bonds. Moreover, rapid overlay of chemical structures? analysis was described to understand the 3D QSAR of synthesized compounds as urease inhibitors. The results emphasize the importance of polar thiosemicarbazide directly linked to 6-substituted quinolone moieties as promising antimicrobial urease inhibitors.

Chemistry of 2-cyanomethylene-4-thiazolidinone

This article is a brief review about the synthesis and chemistry of 2-cyanomethylene-4-thiazolidinone 1. The most significant applications of 4-thiazolidinone 1 in heterocyclic synthesis are due to its two reactive methylenes. The endo-cyclic methylene protons are activated by the neighboring carbonyl moiety and the exo-cyclic methylene protons by the adjacent cyano group. Different types of reactions, such as alkylation, coupling, and Knoevenagel condensation, as well as cyclization reactions are illustrated for the synthesis of different classes of biologically important heterocyclic skeletons from this novel precursor.

A comparative group-QSAR and molecular docking studies of 4 -thiazolidinone containing indolin-2-one moiety as VGEFR inhibitors

Vascular endothelial growth factor receptors (VEGFR) are kinase based receptors reported as a promising target in anti tumour therapy. VGEFR inhibitors are being investigated which can have important contribution in anti-angiogenic therapy for treatment of cancer. In the present study, an attempt has been made to develop a site-specific QSAR model in order to explore the definite sites of substitution of a series of 4-thiazolidinone derivatives having reported antitumor activity against h460 cell lines. Each molecule of the series was divided into seven fragments for varying substituent at the positions R1, R2, R3, R4, R5, R6 and R7 of the parent nucleus. GQSAR was performed using MLR, PCR, PLS and KNN methods of variable selection. Amongst these methods, PCR has come out with promising result as compared to other methods. A comparative docking study was performed to explore the particular sites of interactions within the binding cavity of VGEFR protein. (PDB id: 1Y6A). The important substitutions contributing towards the biological activity by interpreting the developed GQSAR equation using virtual studies were found out which are as follows. position R1 should be substituted with groups with low electro negativity and higher atomic mass, oxygen count at R5 should be increased which would act as hydrogen bond acceptors and total polar surface area at R7 has to be decreased by making substitutions of non polar groups to promote hydrophobic interactions.
