Ja. Cornish et al., INHIBITORS OF THE ADENOVIRUS TYPE-2 PROTEINASE BASED ON SUBSTRATE-LIKE TETRAPEPTIDE NITRILES, Bioorganic & medicinal chemistry letters, 5(1), 1995, pp. 25-30
Tetrapeptides containing the substrate derived P-4-P-1 residues Leu-Al
a-Gly-Gly and C-terminal ester, acid, amide, nitrile and dimethylaceta
l functionalities were synthesised and tested as inhibitors of the ade
novirus type 2 proteinase. The acids and amides did not act as inhibit
ors and the dimethyl acetals and the nitriles served as moderate and g
ood reversible inhibitors respectively.
