Mechanism of action

A distinguishing feature of the BILN 2061 inhibitor series is the presence of C-terminal carboxylic acid functionality. This provides exquisite selectivity with respect to other proteases, a property not easily attained with more conventional classes of covalent, reversible serine protease inhibitors. BILN 2061 blocks NS3 protease-dependent polyprotein processing in HCV replicon-containing cells. It is orally bioavailable in various animal species.
