  • Patent number: 7192920
    Abstract: A subject of the invention, in all possible isomer forms as well as their mixtures, is the compounds of formula (I): in which either R1: H or CH3 and R2: cyclohexyl substituted by an amine, a (CH2)b-C?N 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, CH2C?N, 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.
