A novel class of diastereoselective spiropyrrolidine-oxindole derivatives were synthesized fromisatin, 2-phenylthiazolidine-4-carboxylic acid and chalcone in a one-pot multicomponent reaction via1,3-dipolarcycloaddition. The advantages of this methodology are the mild reaction conditions, high diastereoselectivity and high yield. These derivatives exhibited promising anti-cancer activity against
We report herein the design and synthesis of bioisosteres of spirooxindole (MI-63/219), a small-molecule inhibitors of the MDM2–p53 interaction as anti-breast cancer agents. Compound 5b has been exhibiting significant anti-proliferative activity in nude mice bearing MCF-7 xenograft tumor. The compound 5b was found to act via modulation of MDM2 and p53 expression in breast cancer cells expressing wild
