, (2008/06/13)
A pharmaceutical composition effective in the protection of normal tissues against radiation induced damage comprising administration a compound of the formula in which R1 is a radical corresponding to an amino acid R1 --COOH, /A/ is a C2 or C3 alkylene radical which can be substituted with a C1 to C3 alkyl radical, or with a hydroxy or hydroxycarbonyl radical or a --COR radical where R is an amino or --NH--CH2 --CO2 H radical, R2 is an acyl radical which protects the thiol group and which liberates the thiol group in vivo, R3 is a hydrogen, and also the salts of this compound with pharmaceutically acceptable acids.

A variety of N-(aminoalkanoyl)-S-acylcysteamine and N,N'-bis(aminoalkanoyl)cystamine salt derivatives were synthesized. Toxicity and radioprotective activity (as the dose reduction factor DRF) were determined in vivo on mice and compared to WR 2721 and S-acetylcysteamine hydrochloride. One of the most interesting compounds of this series was N-glycyl-S-acetylcysteamine trifluoroacetate (16, I 102). Structure-activity relationships are discussed.
