A subject of the invention, in all possible isomer forms as well as their mixtures, is the compounds of formula (I): ##STR1##

in which

either R₁: H or CH₃ and

R₂: cyclohexyl substituted by an amine, a (CH₂)b-CN radical or R₁ and R₂ together with the nitrogen which carries them form a ring with 3, 4 or 5 carbons optionally substituted by an amine

R₃: hydrogen, methyl or hydroxyl

R₄: hydrogen or hydroxyl

R: represents a linear, branched or cyclic chain

T: hydrogen, methyl, CH₂CONH₂, CH₂CN, a (CH₂)₂NH₂ or (CH₂)₂Nalk⁺X^- radical, X halogen and alk alkyl

Y: hydrogen, hydroxyl, halogen or OSO₃H,

W: H or OH,

Z: H, CH₃.

The compounds of formula (I) have antifungal properties.
