AB A series of HIV protease inhibitors containing a novel C2 symmetrical
aminodiol core structure were prepared from amino acid starting
materials. The ability of the aminodiols to inhibit HIV replication in
cell culture is comparable to their ability to inhibit the isolated
enzyme, a result compatible with good cell membrane penetration by this
class of compounds. Optimization of the structure-activity in this
series led to aminodiol 9a (Ki = 100 nM; ED50 (HIV-1) = 80 nM)
containing P1/P1 benzyl and P2/P2 Boc substituents. Compound 9a is a
selective inhibitor of HIV protease versus other aspartyl proteases such
as human renin, human cathepsin D, and porcine pepsin. In addition, 9a
is equipotent against HIV-1 and HIV-2 in cell culture and demonstrates
similar activity in infected T-lymphocytes and PBMCs. After i.v. and
oral administration in rats, 9a displayed significant oral
bioavailability (ca. 40%) and a promising plasma elimination half-life
(4 h).
