(EN) There are disclosed herein 2-phenylbenzazole compounds having a 3'-substituent and a 4'-NR5R6 substituent in the phenyl group where R5 and R6 are each hydrogen or alkyl, or where the 4'-NR5R6 substituent is N-acyl (or N-benzoyl). There are also disclosed 2-phenylbenzazole compounds in the form of 4'-N sulphamate salts. Such compounds exhibit significant selective cytotoxic activity in respect of tumor cells and provide potentially useful chemotherapeutic agents for selective treatment of a range of cancers.(FR) Cette invention concerne des composés 2-phénylbenzazole ayant un substituant en 3' et un substituant NR5R6 en 4' dans le groupe phényle, R5 et R6 étant chacun l'hydrogène ou un alkyle, ou le substituant NR5R6 en 4' étant un N-acyle (ou un N-benzoyle). L'invention se rapporte également à des composés 2-phényl-benzazole sous la forme de sels de sulphamate portant N en 4'. De tels composés présentent une activité cytotoxique sélective significative vis-à-vis des cellules tumorales et permettent de disposer d'agents chimiothérapeutiques potentiellement utiles pour le traitement sélectif d'un certain nombre de cancers.
