    摘要: A method of treating medical conditions with proteinase inhibitors of the formula: ##STR1## wherein B is H or an amino acid blocking group for the N-terminal amino acid nitrogen;R.sub.1 is an optionally protected .alpha.-amino acid side chain such that P.sub.2 is the residue of an .alpha.-amino acid selected from the group consisting of phenylalanine (Phe), leucine (Leu), tyrosine (Tyr) and valine (Val), and substituted analogs thereof, particularly including Tyr(OMe);R.sub.2 is an optionally protected .alpha.-amino acid side chain such that P.sub.1 is the residue of an .alpha.-amino acid selected from the group consisting of alanine (Ala), arginine (Arg), aspartic acid (Asp), glutamic acid (Glu), histidine (His), homophenylalanine (HPhe), phenylalanine (Phe), ornithine (Orn), serine (Ser) and threonine (Thr), and substituted analogs thereof;X is a fluorine-free leaving group selected from the group consisting of phenoxy, substituted phenoxy and heterophenoxy;E and G are one or more atoms more electronegative than carbon; andD is hydrogen, methyl or a substituted methyl.

    摘要: Peptide thioneamides are provided as synthetic substrates for cysteine proteases. The compounds of the invention are peptides consisting of one or more blocked or unblocked amino acids wherein the terminal carboxy of the peptides are thionated and forms a thioneamide linkage with a fluorogenic or chromogenic leaving group. The alpha carbonyls of the remaining amino acids are thionated or unthionated. The invention includes methods and kits for using the peptide thioneamides.
