    Synthesis and evaluation of α,α-disubstituted-3-mercaptopropanoic acids as inhibitors for carboxypeptidase A and implications with respect to enzyme inhibitor design
    摘要:
    2-Ethyl-2-meth% 1-3-mercaptopropanoic acid (6) and 2-benzyl-2-methyl-3-mercaptopropanoic acid (7) were synthesized and evaluated as inhibitors for carboxypeptidase A (CPA), a prototypical zinc protease with the expectation that the binding affinities of these inhibitors would be augmented over those of 2-ethyl-3-methylsuccinic acid (2) and 2-benzyl-3-methylsuccinic acid (3), respectively, in light of the fact that the sulfhydryl group is a better zinc coordinating moiety than the carboxylate group. Contrary to the expectation. however. the inhibitory potency of 6 was not improved and that of 7 was rather attenuated by the replacement. A probable explanation for the unexpected results is offered. (C) 2003 Elsevier Ltd. All rights reserved.

    (EN) The invention relates to a technetium chelate of general formula (I), wherein X is a sulphur atom or an imino group, Z is a hydrogen atom, a carboxy group, an alkoxycarbonyl group having 1-4 carbon atoms, an aminocarbonyl group, a sulpho group, an aminosulphonyl group or a carboxymethylaminocarbonyl group, Tc represents technetium-99m, and each of the symbols R1 to R8 is individually selected from the group consisting of hydrogen and C1-C4 straight or branched alkyl, which alkyl group is optionally substituted with an amino group, a hydroxy group, a mercapto group, a halogen atom, a carboxy group or an aminocarbonyl group, with the proviso that at least both R1 and R2 or both R3 and R4 or both R5 and R6 or both R7 and R8 represent optionally substituted alkyl groups; as well as water-soluble salts of these compounds. The invention also relates to a tripeptide compound to be used for preparing said chelate and to a kit comprising a composition of said tripeptide compound.(FR) L'invention se rapporte à un chélate de technétium représenté par la formule générale (I), où X représente un atome de soufre ou un groupe imino, Z représente un atome d'hydrogène, un groupe carboxy, un groupe alcoxycarbonyle ayant 1 à 4 atomes de carbone, un groupe aminocarbonyle, un groupe sulfo, un groupe aminosulfonyle ou un groupe carboxyméthylaminocarbonyle, Tc représente du technétium 99m, et chacun des symboles R1 à R8 est choisi séparément dans le groupe constitué par hydrogène et alkyle à chaine droite ou ramifiée C1-C4, ce groupe alkyle étant éventuellement substitué par un groupe amino, un groupe hydroxy, un groupe mercapto, un atome d'halogène, un groupe carboxy ou un groupe aminocarbonyle, à condition qu'au moins à la fois R1 et R2 ou à la fois R3 et R4 ou à la fois R5 et R6 ou à la fois R7 et R8 représentent des groupes alkyle éventuellement substitués; ainsi qu'à des sels hydrosoluble de ces composés. L'invention se rapporte également à un composé de tripeptides destiné à être utilisé pour préparer ce chélate et à un kit comprenant une compostion de ce composé de tripeptides.
