title: Aminothiols: synthesis and effect on chicken brain aminopeptidases.
abstract: An amino acid derivative, leucinethiol, was reported to be a strong inhibitor of aminopeptidase activity. In order to obtain selective inhibitors of various brain aminopeptidases, we tested the inhibition by amino acid analogs of brain aminopeptidase activity. In particular, we synthesized the trifluoroacetyl derivatives of phenylalaninol, tyrosinol, and leucinol; leucinethiol; and phenylalaninethiol and measured their effect on soluble puromycin-sensitive aminopeptidase S1 and SII purified in our laboratory. Two of the compounds, L-bis (1-thio-2-amino-4-methylpentane) dihydrochloride (TAMP) and L-bis (1-thio-2-amino-3-phenylpropane) dihydrochloride (TAPP), caused significant inhibition.
