Phosphonate substituted compounds with HIV protease inhibitory properties having use as therapeutics and for other industrial purposes are disclosed. The compositions inhibit 5 HIV protease activity and/or are useful therapeutically for the treatment of AIDS and other antiviral infections, as well as in assays for the detection of HIV protease.
Compounds of the invention, such as compounds of Formulae Ia, Ib, Ic, or Id and pharmaceutically acceptable salts, isomers, and prodrugs thereof, which are useful as modulators of the activity of liver X receptors, where R1, R2, R21, R3, and G are defined herein. Pharmaceutical compositions containing the compounds and methods of using the compounds are also disclosed.
(Benzyloxycarbonyl)- and (tert-butoxycarbonyl)hydrazones are easily reduced by sodium cyanoborohydride in acidic medium. The method is an alternative to catalytic hydrogenation and allows ready access to both N-benzyloxycarbonyl and N-tert-butoxycarbonyl protected N′ -alkyl- and N′-arylmethylhydrazines. The products can be isolated as the solid, stable cyanoborane adducts.
