A series of 5,5-disubstituted hydantoin derivatives was synthesized by alkylating 5,5-bis(mercaptomethyl)-2,4- imidazolidinedione (3) with various halomethylaromatic or halomethylheteroaromatic precursors, or by using the Buchener–Berg procedure on the required ketone. When evaluated for their ability to inhibit HIV-induced cell killing and virus production in CEM or MT-2 cells only compounds 2, 4n, 4o, and 4i demonstrated modest activity, the latter with an IC50 = 53 μ. © 1992, American Chemical Society.
