The present invention relates to fosamprenavir calcium (Ia) substantially free of isomer impurity, (3R) tetrahydro -3 -furanyl(1S,2R)-3-[[(4-aminophenyl)sulfonyl](isobutyl)amino]-1-benzyl-2-(phosphonooxy)propyl carbamate (Ib), and its process for preparation thereof. The present invention also provides fosamprenavir calcium intermediate, (S)-3-tetrahydrofuranyl-N-succinimidyl carbonate (IIa) substantially free of (R)-3-tetrahydrofuranylsuccinimidyl carbonate (IIb) and its process for preparation thereof.
The present invention relates to a novel class of sulfonamides which are aspartyl protease inhibitors. In one embodiment, this invention relates to a novel class of HIV aspartyl protease inhibitors characterized by specific structural and physicochemical features. This invention also relates to pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well suited for inhibiting HIV-1 and HIV-2 protease activity and consequently, may be advantageously used as anti-viral agents against the HIV-1 and HIV-2 viruses. This invention also relates to methods for inhibiting the activity of HIV aspartyl protease using the compounds of this invention and methods for screening compounds for anti-HIV activity.

Building from the results of a computational screen of a range of triazole-containing compounds for binding efficiency to human immunodeficiency virus type 1 protease (HIV-1-Pr), a novel series of potent inhibitors has been developed. The copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC), which provides ready access to 1,4-disubstituted-1,2,3-triazoles, was used to unite a focused library of azide-containing

strategy of epoxide opening by amine with water as co-solvent and screening in situ was developed for rapid discovery of protein inhibitors. Using this approach, HIV protease inhibitors with novel P1' residues were identified in our study. This strategy should be applicable for the efficient assembly of diverse compound collections for inhibitors' discovery and optimization in other systems.

A series of potent HIV-1 protease inhibitors with a lipophilic adamantyl P1 ligand have been designed, synthesized, and evaluated. We have developed an enantioselective synthesis of adamantane-derived hydroxyethylamine isosteres utilizing Sharpless asymmetric epoxidation as the key step. Various inhibitors incorporating P1-adamantylmethyl in combination with P2 ligands such as 3-(R)-THF, 3-(S)-THF
已经设计、合成和评估了一系列具有亲脂性金刚烷基 P1 配体的强效 HIV-1 蛋白酶抑制剂。我们利用 Sharpless 不对称环氧化作为关键步骤开发了金刚烷衍生的羟乙胺等排体的对映体选择性合成。检测了结合 P1-金刚烷基甲基和 P2 配体的各种抑制剂,例如 3-( R )-THF、3-( S )-THF、双-THF 和 THF-THP。S1' 口袋也用苯基和苯甲基配体进行了探测。具有异丁基 P1' 配体和双 THF P2 配体的抑制剂15d被证明是该系列中最有效的。与抑制剂2相比,抑制剂15d的 cLogP 值有所提高与苯甲基 P1-配体。15d、15h和15i与 HIV-1 蛋白酶复合物的 X 射线结构研究揭示了抑制剂-蛋白质相互作用的分子洞察力。
