A compound of the general formula (I): ** (See formula) ** in which: R2 'is SO3H or SO3- / M + and R3' is H, or R2 'is H and R3' is SO3H or SO3- / M +; M + is the cation of a metal, such as Na +, K +; R2 and R3, identical or different, are independently selected from: a) fatty acyl groups of the formula -C> = O- (CH2) k-CH3, where k is an integer from 14 to 50; b) ** (See formula) ** in which r is 1; l is an integer chosen from 0 to 10; q is an integer chosen from 0 to 50; provided that l + q> = 1; T2 is methyl; each Ti is methyl; in which at least one of R2 and R3 is b); and its enantiomers, diastereoisomers, mixtures thereof and pharmaceutically acceptable salts. |
