Design, synthesis, and biological evaluation of novel 3-pyrrolo[b]cyclohexylene-2-dihydroindolinone derivatives as potent receptor tyrosine kinase inhibitors
摘要:
A novel series of 3-pyrrolo[b]cyclohexylene-2-dihydroindolinone derivatives targeting VEGFR-2, PDGFR-beta and c-Kit kinases were designed and synthesized. The molecular design was based on the SAR features of indolin-2-ones as kinase inhibitors. SAR study of the series allowed us to identify compounds possessing more potent inhibitory activities against the three kinases than sunitinb with IC50 values in the low nanomolar range in vitro. Additionally, some compounds also showed favorable antiproliferative activities against a panel of cancer cell lines (BXPC-3, T24, BGC, HEPG2 and HT29). (C) 2013 Elsevier Ltd. All rights reserved.
