Herein we report the design, synthesis, X–ray structural, and biological studies of an exceptionally potent HIV–1 protease inhibitor, compound 5 ((3S,7aS,8S)–hexahydro–4H–3,5–methanofuro[2,3–b]pyran–8–yl ((2S,3R)–4–((2–(cyclopropylamino)–N–isobutylbenzo[d]thiazole)–6–sulfonamido)–1–(3,5–difluorophenyl)–3–hydroxybutan–2–yl)carbamate). Using structure–based design, we incorporated an unprecedented 6–5–5–ring–fused crown–like tetrahydropyranofuran as the P2–ligand, a cyclopropylaminobenzothiazole as the P2'–igand, and a 3,5–difluorophenylmethyl group as the P1–ligand. The resulting inhibitor 5 exhibited exceptional HIV–1 protease inhibitory and antiviral potency at the picomolar level. Furthermore, it displayed antiviral IC50 values in the 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 inhibitory activity toward dimerization as well as favorable central nervous system penetration. Here, we determined a high–resolution X–ray crystal structure of the complex between inhibitor 5 and HIV–1 protease, which provides molecular insight into the unprecedented activity profiles observed.
