Sulfonylguanidines are interesting bioactive compounds with a broad range of applications in the treatment of different pathologies. 2‐Aminobenzazole‐based structures are well employed in the development of new anticancer drugs. Two series of novel N‐benzazol‐2‐yl‐N′‐sulfonyl guanidine derivatives were synthesized with the sulfonylguanidine in either an extra‐ or intracyclic frame. They were evaluated for their antiproliferative activity against malignant melanoma tumor cells, thus allowing structure‐activity relationships to be defined. Additionally, NCI‐60 screening was performed for the best analogue to study its efficiency against a panel of other cancer cell lines. The stability profile of this promising compound was then validated. During the synthetic process, an unexpected new deamidination of the sulfonylguanidine towards sulfonamide function was also identified.
