Patent ID: 7022317

Claim:
A 2-oxothiazolidine-4-carboxylic acid derivative of formula (I): in which: X represents an oxygen atom or a radical NR″; R″ represents a linear, cyclic or branched alkyl radical containing from 1 to 12 carbon atoms, which is optionally substituted; Y represents a group (CH 2 ) n ; Z represents a group (CRR′) n is an integer chosen from 0, 1, 2 and 3; R and R′, which may be identical or different, represent: a hydrogen atom; an —Si—(CH 3 ) 3 , —Si(CH 3 ) 2 —OH, Si—(CH 3 ) 2 —OEt, —Si—(CH 3 ) 2 —O—CH 2 —Ph or —Si—(iPr) 2 —OEt radical; a halogen; an alkyl radical as defined above; an optionally substituted aryl radical; an optionally substituted arylalkyl radical; wherein when X represents a radical NR″, R″ and R′ taken together can form, with the 2 atoms bearing them, a heterocycle containing 4, 5 or 6 carbon atoms; or wherein Y and Z each represent a carbon atom and together form an aromatic heterocycle or ring containing 5, 6 or 7 carbon atoms, the said ring or heterocycle being optionally substituted; and the optical or geometrical isomers thereof, alone or as a mixture in all proportions, and the physiologically acceptable salts thereof.
