A series of sulfonyl-N-hydroxyguanidine derivatives was designed and synthesized for cytotoxic evaluation as potential anticancer agents on the basis of the lead compound LY-181984. Replacement of the ureido moiety of the lead compound with hydroxyguanidine provided a stable cytotoxicagent. The conformation of sulfonyl-N-hydroxyguanidine derivatives, such as N-(4-chlorophenyl)-N'-[(benzo[2,1,3]th
