Abstract:
The invention relates to a compound of the 5-acylsulfanyl-histidine type and the derivatives thereof, of general formula (I), wherein R1 to R3=H, alkyl, especially CH3; R4=H, alkyl, especially CH3, alkyle(C=0), substituted alkyl (C═O), aryl (C═O); β-alanyl (H2NCH2CH2 (C═O); α-amino-acyl; R5=alkyl, especially methyl, phenyl. The invention also relates to the use of said compound for producing compounds of the 5-sulfanyl-histidine type and the derivatives thereof, in addition to corresponding disulfides; and to the various methods for the production thereof.

Claim (Index 21):
A compound of the 5-sulfanylhistidine of formula (II): where: R1=H, or alkyl; R2=R3=H, or alkyl; R4=H, alkyl, alkyl (C\u2550O), substituted alkyl (C\u2550O), aryl (C\u2550O), \u03b2-alanyl (H2NCH2CH2 (C\u2550O), or \u03b1-amino-acyl; R 1  to R 4  being as defined above; it being understood that when R 1 \u2550H then R 2 , R 3  and R 4  cannot simultaneously be H. As well as all the stereoisomers, diastereoisomers and enantiomers, in particular in terms of the carbon atom bearing the COOH group, as well as all the corresponding disulfides, taken separately or in a mixture; all the salts of pharmaceutically acceptable acids of said compounds of general formula (II).
