Capped dipeptide α-Ketoacid inhibitors of the HCV NS3 protease
摘要:
The N-terminal aminoacid of alpha-ketotripeptide inhibitors of the hepatitis C virus NS3 protease can be replaced with an alpha-hydroxy acid, leading to capped dipeptide inhibitors such as 20 with an IC50 value of 3.0 muM. The importance of the lipophilic side chain interactions at S3 of the protease and the requirement of the capping residue with R configuration have been explained by molecular modeling studies.

be reversed to perform nucleophilic C1 -extensions of various aldehydes to yield the corresponding 2-hydroxyacyl-CoA thioesters. We improved the catalytic properties of Methylorubrum extorquens OXC by rational enzyme engineering and combined it with two newly described enzymes-a specific oxalyl-CoA synthetase and a 2-hydroxyacyl-CoA thioesterase. This enzymatic cascade enabled continuous conversion

α‐hydroxycarboxylic acids, including pharmaceutical precursors, from readily accessible α‐hydroxymalonates. The enzymatic method described here represents an improvement upon existing synthetic chemistry methods that have been used to produce similar compounds. The relationship between the structural features of these new substrates and the kinetics associated with their enzymatic decarboxylation is explored
