    Design, synthesis, biological and X-ray crystallographic studies of a series of potent HIV-1 protease inhibitors are described. Various polar functionalities have been incorporated on the tetrahydropyranyl-tetrahydrofuran-derived P2 ligand to interact with the backbone atoms in the S2-subsite. The majority of the inhibitors showed very potent enzyme inhibitory and antiviral activity. Two high-resolution X-ray structures of 30b- and 30j-bound HIV-1 protease provide insight into ligand-binding site interactions. In particular, the polar functionalities on the P2-ligand appear to form unique hydrogen bonds with Gly48 amide NH and amide carbonyl groups in the flap region.
