Identification and synthesis of N′-(2-oxoindolin-3-ylidene)hydrazide derivatives against c-Met kinase
摘要:
A series of N'-(2-oxoindolin-3-ylidene)hydrazide derivatives were identified as moderately potent inhibitors against c-Met kinase by pharmacophore-based virtual screening and chemical synthesis methods. The structure-activity relationship (SAR) at various positions of the scaffold was investigated and its binding mode with c-Met kinase was analyzed by molecular modeling studies. In this study, two potent compounds D2 and D25, with IC50 value at 1.3 mu M and 2.2 mu M against c-Met kinase respectively, were identified. Finally, based on the clues extracted from this study, future development for the optimization of this scaffold was discussed. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract Based on the existing reports on the bioactive isatin derivatives, a number of Schiff bases were synthesized by reacting 5-substituted isatins with bioactive amines/hydrazides and their structures were confirmed using spectroscopic methods such as NMR, IR and massspectrometry. Furthermore, N -benzylation of isatin followed by the Schiff base formation furnished a new series of compounds (
