light on the pivotal role of its peculiar vinylsulfoxide sidechain towards its cytotoxic and antimicrobial properties, especially dependant upon the presence and oxidation state of sulfur. The reaction of dirchromone with cysteamine revealed a surprising Michael acceptor behavior with elimination of the methylsulfinyl moiety and redox transformation of the sulfur atom that could be involved in the mode

A series of 1-[[p-[2-(acylamino)ethyl]phenyl]sulfonyl]-2-iminoimidazolidines has been synthesized. Compounds from this new class of oral hypoglycemic agents lower blood glucose in normal and in streptozotocin-diabetic rats. Potent analogues were obtained by modification of the acyl residue. 1-[[p-[2-(Crotonylamino)ethyl]phenyl]-sulfonyl]-3-cyclohexyl-2-iminoimidazolidine (44) turned out to be the most potent compound in the normal rat (20 times tolbutamide), and 1-[[p-[2-(5-methylisoxazole-3-carboxamido)ethyl]phenyl]sulfonyl]-3-cyclohexyl-2-imino-imidazolidine (30) displayed the highest potency in the diabetic rat (similar to phenformin).
