Furin is a subtilisin-like eukaryotic serine endoprotease which processes proproteins to biologically active proteins and peptides. Also, the envelope proteins of viruses, such as influenza and HIV viruses, need to be processed by furin for infectivity. This enzyme has a consensus substrate specificity for Arg-Xxx-Lys/Arg-Arg at the cleavage site. Two kinds of transition state analog peptides were designed and tested in vitro with furin. The ketomethylene series, Psi(COCH2), have K-i's in the submicromolar range; the aminomethyl ketone series, Psi(COCH2NH), have Ki's in the nanomolar range. The best inhibitor is Dec-Arg-Val-Lys-Arg-CH2-Ala-Val-Gly-NH2(2c) with a K-i of 3.4 nM.

and tert-butyloxycarbonylamino acids were synthesized by the N,N'-dicyclohexylcarbodiimide (DCC) method from the acids and 6-chloro-2-hydroxypyridine in dimethylformamide (DMF). The reactivity of the 6-chloro-2-pyridylester with amino group is much higher than that of the corresponding 2-pyridyl ester (OPy) and p-nitrophenyl esters (ONp) in dioxane and DMF, and a peptide bond is formed without acylation

The biphenyl-containing pseudo-amino acids2′-(aminomethyl)biphenyl-2-carboxylicacid (Abc; 1) and 2′-(aminomethyl)biphenyl-2-acetic acid (Aba; 2) are used as rigid spacers in the backbone of the cyclic peptides cyclo (-Abc-Ala-Phe-Gly-)2 (5), cyclo(-Abc-Ala-Val-Gly-)2 (6), cyclo(-Aba-Gly-Phe-Ala-)2 (7), and cyclo(-Aba-Ala-Phe-Gly-)2(8). Three different interconverting diastereoisomers are found in
