(57) Abstract: The compound or a salt thereof of the general formula (I): in A-B-N (O) S [ wherein, s is an integer equal to 1 or 2; A = R-T 1 - a and Where R is the residue of the drug and T 1 = (CO) t or (X) t ′ , where X = O, S, NR 1C and R 1C is H or linear. T or t ′ is t = 1 when t ′ = 0 and t = 0 when t ′ = 1, with the condition that t = 0. or be equal to one integer; B = -T B -X 2 -O- and and, where a T B = (CO) when t = 0, at T B = X when t '= 0 And X is as defined above; the divalent group X 2 is such that the precursor of A and the precursor of B are each compatible with the pharmacological tests described herein. |
