  • PubMed Abstract: 

    We describe the design, synthesis, and biological evaluation of a series of novel HIV-1 protease inhibitors with carboxamide derivatives as the P2 ligands. We have specifically designed aminothiochromane and aminotetrahydronaphthalene-based carboxamide ligands to promote hydrogen bonding and van der Waals interactions in the active site of HIV-1 protease. Inhibitors 4e and 4j have shown potent enzyme inhibitory and antiviral activity. High resolution X-ray crystal structures of 4d- and 4k-bound HIV-1 protease revealed molecular insights into the ligand-binding site interactions.
