We report here the design, synthesis, X-ray-structural, and biological studies of an exceptionally potent HIV-1 protease inhibitor 5. In this inhibitor, we incorporated an unprecedented structure-based designed 6-5-5-ring fused crown-like tetrahydropyranofuran as the P2-ligand, a cyclopropylaminobenzothiazole as the P2'-ligand and 3,5-difluorophenylmethyl as the P1-ligand. The resulting inhibitor 5, exhibited exceptional HIV-1 inhibitory and antiviral potency at picomolar level. Furthermore, it displayed antiviral IC50 values in picomolar range against a wide panel of highly multidrug-resistant HIV-1 variants. The inhibitor shows an extremely high genetic barrier against the emergence of drug-resistant variants. It also showed extremely potent dimerization inhibitory activity and penetrated CNS favourably. We have determined a high resolution X-ray structure of inhibitor 5-bound HIV-1 complex which provided molecular insight into the unprecedented activity profiles.
