A subject of the invention, in all possible isomer forms as well as their mixtures, is the compounds of formula (I): ##STR00001## in which either R.sub.1: H or CH.sub.3 and R.sub.2: cyclohexyl substituted by an amine, a (CH.sub.2)b-C.ident.N radical or R.sub.1 and R.sub.2 together with the nitrogen which carries them form a ring with 3, 4 or 5 carbons optionally substituted by an amine R.sub.3: hydrogen, methyl or hydroxyl R.sub.4: hydrogen or hydroxyl R: represents a linear, branched or cyclic chain T: hydrogen, methyl, CH.sub.2CONH.sub.2, CH.sub.2C.ident.N, a (CH.sub.2).sub.2NH.sub.2 or (CH.sub.2).sub.2Nalk.sup.+X.sup.- radical, X halogen and alk alkyl Y: hydrogen, hydroxyl, halogen or OSO.sub.3H, W: H or OH, Z: H, CH.sub.3. The compounds of formula (I) have antifungal properties.
