angiogenesis and cancer progression. In this study, we are reporting the design, synthesis and biological evaluation of a series of 4-substituted thieno[2,3-d]pyrimidine derivatives as VEGFR-2 inhibitors. The design of these compounds was based on interactions extracted from crystal structure of potent pyrrolo[3,2-d]pyrimidine inhibitor VIII with VEGFR-2 (PDB: 3VHE). In addition to these interactions, the

This study is concerned with the implementation of structure-based techniques for the design of new heterocyclic compounds based on pseudosaccharine scaffold with protein kinase inhibition activity. This nucleus was exploited based on the well-known quinazoline core and its interactions with several protein kinases. Two series of compounds employing this new scaffold were synthesized and evaluated at enzymatic and cellular levels. Compound 9b displayed broad spectrum antiproliferative activity on NCI 60-cell lines panel with mean GI(50) of 5.4 mu M. Investigation of the molecular mechanism showed probable inhibitory activity against Src kinase. (C) 2012 Elsevier Masson SAS. All rights reserved.
Synthesis and biological evaluation of di-aryl urea derivatives as c-Kit inhibitors
Inhibition of receptor tyrosine kinases (RTKs) continued to be a successful approach for the treatment of many types of human cancers and many potent small molecules kinase inhibitors have been discovered the last decade. In the present study, we describe the synthesis of thienopyrimidine derivatives and their pharmacological evaluation against nine kinases (EGFR, PDGFR-ss, c-Kit, c-Met, Src, Raf, VEGFR-1, -2 and -3). Most of the synthesized compounds showed from moderate to potent activities against c-Kit with IC50 values in the nanomolar range. Among them, 4-anilino(urea) thienopyrimidine analogs showed selectivity and potent c-Kit inhibition with IC50 values less than 6 nM. Docking simulation was performed for the most promising compound 9 into the c-Kit active site to determine the potential binding mode. This study reveal that the 4-anilino(urea) thienopyrimidine is an interesting scaffold to design novel potent and selective c-Kit inhibitors which may make promising candidates for cancers where c-Kit receptors are overexpressed.
