New 5-Substituted Derivatives of Ethyl 2,3-Dihydro-3-oxoisothiazolo[5,4-b]pyridine-2-acetate
摘要:
New series of ethyl 5-substituted 2,3-dihydro-3-oxoisothiazolo[5,4-b] pyridine-2-acetate was prepared either a) directly by reaction of 5-substituted 2-chlorothio-3-pyridinecarbonyl chlorides with ethyl glycinate or b) by oxidation of the correspondent 2-mercapto-3-pyridinecarboxamides. New 5-substituted 1,2-dihydro-2-thioxo-3-pyridinecarboxylic acids as starting materials are described.

search for new derivatives with anticancer activity that are able to induce a selective pro‐apoptotic mechanism in cancer cells, we have designed, synthesized, and evaluated a series of new 2‐(alkylsulfanyl)‐N‐alkylpyrido[2,3‐d]pyrimidine‐4‐amine derivatives as cytotoxic and apoptosisinducers. The potential antitumor activity of the compounds was evaluated in vitro by examining their cytotoxic effects against
