Claim:
Compounds of the general formula (I): in which: X=O or S; R1 is chosen from: Alk-COOH, Alk-C(═O)—(O) m —Ar, Alk-C(═O)—(O) m -Het, Alk-C(═O)—(O) m -Alk, Alk-C(═O)—(O) m -cycloalkyl, Alk-C(═O)NRR′, Alk-(O) m —Ar, Alk-O-Alk, Alk-O-Alk-Ar, Alk-O-Het, R2 is chosen from -Alk, —Ar and -cycloalkyl; R3, R4, R5 and R6, which may be identical or different, are chosen independently from H, -Hal, —OH, -Alk, —OAlk, —CN, —CF 3 , —NRR′ and —NO 2 ; in which, in the definitions of R1-R6: each of the Alk, which may be identical or different, is optionally and independently substituted by one or more groups chosen from -Hal, —OAlk, —Ar, —OAlkAr, —OH, —CN, —OAr, —CF 3 , —COOH, —NRR′, —C(═O)—(O) m Alk, -Het and —NO 2 ; each of the Ar, which may be identical or different, is optionally and independently substituted by one or more groups chosen from -Hal, —OAlk, -Alk, —Ar, —OAlkAr, —OH, —CN, —OAr, —CF 3 , -AlkAr, —COOH, —C(═O)—(O) m Alk, -Alk-C(═O)—(O) m -Alk, —NRR′, -Het, —NO 2 , —S(O) n Ar and —S(O) n Alk; R and R′ are chosen independently from H and Alk; m=0 or 1; and also the stereoisomers thereof, the racemates thereof and the pharmaceutically acceptable salts, with the exception of the compounds for which: 1) R1=—CH 2 —C(═O)Me, R2=-Me, X=O, R3, R5=H and each R4, R6=H or OMe.
