Small-molecule dimerization inhibitors of wild-type and mutant HIV protease: a focused library approach.
We demonstrate that a focused library based on truncated, cross-linked interfacial peptides of HIV-1 protease produces effective dimerization inhibitors of the enzyme. By combining individual changes of the library into a single compound, we obtained a significantly more potent agent and found that an additive increase in inhibitor efficacy was obtained. The good activity of library members against an active-site drug-resistant protease mutant bodes well for dimerization inhibition as a complementary method to targeting the active site.
