Abstract
Introducing an aryl moiety to our previous pyrrolidone scaffold by molecule fusing strategy afforded two sets of isopropylether-pyrrolidone and α-phenylethylamine-pyrrolidone derivatives. Two novel compounds 8b and 8g of the latter serial showed potent p53-MDM2 inhibitory activities with Ki values of 90nM which were three-time higher than that of the parent compound. We also confirmed compound 8b can activate p53 proteins in lung cancer A549 cells. The results offered us valuable information for further lead optimization.
