2-[4-sulfonyl-2-oxoazetidinyl-1]-2-(isopropyliden)acetic acid esters, 2-[4-sulfonylthio-2-oxoazetidinyl-1]-, and 2-[4-sulfothio-2-oxoazetidinyl-1]-2-(isopropenyl)acetic acid esters, cytotoxic activityAbstract
4-Sulfonylazetidinones-2 were synthesized by the reaction of DBU and organic halides with the esters of penicillin sulfones. 4-Sulfonylthio- and 4-sulfothioazetidinones-2 were synthesized by nucleophilic substitution of the 2-benzothiazolylthio groups in 4-(benzothiazolylthio)azetidinones-2 using sodium sulfinates or sodium hydrogen sulfite. A study of their cytotoxic activities revealed the anticancer effect of compounds containing methylsulfonylthio-, 4-tolylsulfonylthio-, and 4-methoxycarbonylamino-phenylsulfonylthio-substituents at position 4 of the β-lactam ring relative to a wide range of monolayer cultures of cancer cells in vitro.
