Synthesis, anticancer activity and docking of some substituted benzothiazoles as tyrosine kinase inhibitors
摘要:
Protein tyrosine kinases occupy a central position in the control of cellular proliferation and its inactivation might lead to the discovery of a new generation anticancer compounds. Substituted benzothiazoles have been found to mimic the ATP-competitive binding of genistein and quercetin to tyrosine kinase. A series of novel 2-phenyl-1,3-benzothiazoles were synthesized and characterised by IR, H-1 NMR and mass spectroscopy. All the compounds were tested for their anticancer activity against MCF-7 breast cancer cell line with the MTT assay. Most of the compounds showed moderate to good anti-breast cancer activity. Anticancer activity varied with substitution on the benzothiazole nucleus with halogens and at 4 position, substitution of the 2-phenyl moiety with methyl and methoxy groups was also explored. Among the compounds tested with MTT assay, mono fluoro substitution on benzothiazole nucleus and 4'-methyl variations at 2-phenyl position demonstrated highest percent growth inhibition of MCF-7 cells. Docking studies of the synthesised compounds was done on EGFR using GRIP batch docking method to study their observed activity. (C) 2010 Elsevier Inc. All rights reserved.

The synthesis and in vitro antitumour evaluation of a new series of fluorinated benzothiazole-substituted 4-hydroxycyclohexa-2,5-dienones ('quinols') is described. The new compounds were found to be of comparable activity compared to the nonfluorinated precursor PMX 464, in terms of antiproliferative activity in sensitive human cancer cell lines (nanomolar GI(50) values) and inhibitory activity against the thioredoxin signalling system.
