Evaluation of furofuran as a P2 ligand for symmetry-based HIV protease inhibitors
摘要:
The hexahydrofurofuranyloxy group was evaluated as a conformationally constrained Pt ligand for symmetry-based HIV protease inhibitors. A number of compounds showed nM level activity against HIV in MT4 cells and lower protein binding than the licensed protease inhibitor ritonavir. However, replacement of 5-thiazole of ritonavir with a furofuran caused a reduction of the bioavailability in vivo. Copyright (C) 1996 Elsevier Science Ltd
The present invention relates to a non-solvated crystalline Darunavir, process for its preparation and pharmaceutical composition comprising it. The present invention also relates to a process for the preparation of amorphous Darunavir from a non-solvated crystalline Darunavir.
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.
