| Abstract: | Some of synthetic bicyclic and polynuclear heterocyclic compounds based on pyridine scaffold were tested as in vitro antitumor agents, and these compounds found to exhibit interesting activities. Fused heterocycles containing sulfur such as thienopyridine, pyridothiazine, and some related fused heterocycles as new ring systems were achieved. Bicyclic thienopyridine 6 and pyrido3,2‐e]1,3]thiazin‐4(3H)‐one 7 exhibited good antitumor activities compared with 5‐fluorouracil. |
