摘要:
Selected tripeptide and tetrapeptide halomethyl ketones are employed in processes for treating viral infection in mammals. These compounds inhibit picornavirus protease activity.
摘要:
A general method for preparing specific inhibitors of virus-specified proteases is disclosed. The inhibitors comprise a halomethyl ketone or methyl ketone moiety covalently linked to a peptide sequence of three, four or five amino acids or amino acid residues, which peptide sequence corresponds to an amino acid sequence found adjacent to and upstream of a cleavage site recognized by a virus-specified protease.

摘要:
Peptide and amino acid halomethyl ketones are employed in processes for inhibiting cyclic nucleotide independent protein kinase activity and tumor cell growth.
摘要:
A peptide affinity label of the formula (I): ##STR1## wherein X is a radical capable of acting as a leaving group in a nucleophilic substitution reaction;A is an aromatic amino acid residue;B is H, or a C.sub.1 -C.sub.4 alkyl group, or aryl;Y is selected from the group consisting of hydrogen, aroyl, C.sub.1 -C.sub.6 acyl, and Q--(A)--.sub.n, whereinQ=hydrogen, aroyl, or C.sub.1 -C.sub.6 acyl,n=1-10,A is an amino acid residue selected from the aliphatic, hydroxy-containing, carboxylic acid group, and amide-thereof-containing, aromatic, sulfur-containing and imino-containing amino acids; and wherein J is selected from the group consisting of --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --,--CH.sub.2 --CH.sub.2 --CH.sub.2 --, --CH.dbd.CH-- and --CH(OH)--CH.sub.2. The affinity label is useful for irreversibly inactivating thrombin and trypsin-like enzymes and may be used as a potential anticlotting agent.
