Given that receptor tyrosine kinases (RTKs) have emerged as key regulators of all aspects of cancer development, including proliferation, invasion, angiogenesis and metastasis, the RTK family represents an important therapeutic target for anti-cancer drug development. Oxindole structure has been used in RTK inhibitors such as SU4984 and intedanib. In this study, two series of new heterocyclic compounds containing oxindole scaffold have been designed and synthesized, and their inhibitory activity against the proliferation of nine cancer cell lines has been evaluated. Among them, compounds 9a and 9b displayed the strongest anti-proliferative activity with the IC(50)s below 10 mu M. Flow cytometric analysis showed that the compounds 9a and 9b dose-dependently arrested the cell cycle at G0/G1 phase. Although the leading compounds SU4984 and intedanib targets FGFR1, the kinase activity test revealed that these compounds only showed slight inhibitory activity on FGFR1 kinase. Further enzymatic test aided by molecular docking simulation in the ATP-binding site demonstrated that 9a and 9b are potent inhibitors of c-Kit kinase. These compounds are worthy of further evaluation as anticancer agents. (C) 2014 Elsevier Ltd. All rights reserved.
