摘要

The invention concerns medicines containing as active principle at least one compound of formula (I) in which: either R1 represents a -CH(Ra)-CHOH-CHOH-CH2OH chain and R2 represents a -CH2-CHOH-CHOH-CH2OH chain, or R1 represents a -CHOH-CHF-CHOH-CH2OH chain, and R2 represents a -CH2-CHF-CHOH-CH2OH chain, or R1 represents a CHOH-CHOH-CHOH-Rb chain, and R2 represents a -CH2-CHOH-CHOH-Rb chain, or R1 represents a -CH2-CHOH-CHOH-CH2OH chain and R2 represents a -CH2-CHOH-CHOH-CH2OH chain, or R1 and R2 are identical and represent each a -(CHOH)n-CH2OH chain in which n is equal to 1, 2, 3, or 4, Ra represents a C1-C6 alkoxy radical or a fluorine atom and Rb represents a carboxy, -CO-NH2 or -CH2-NH2 radical, their stereoisomers. their salts, the novel derivatives of formula (I) and their preparation.
