Enantioselective Synthesis and Selective Monofunctionalization of (4R,6R)-4,6- Dihydroxy-2,8-dioxabicyclo[3.3.0]octane

Disubstituted Bis-THF Moieties as New P2 Ligands in Nonpeptidal HIV-1 Protease Inhibitors (II)

A series of darunavir analogues featuring a substituted bis-THF ring as P2 ligand have been synthesized and evaluated. Very high affinity protease inhibitors (PIs) with an interesting activity on wild-type HIV and a panel of multi-PI resistant HIV-1 mutants containing clinically observed, primary mutations were identified using a cell-based assay. Crystal structure analysis was conducted on a number of PI analogues in complex with HIV-1 protease.

High affinity protease inhibitors (PIs) with an interesting activity on wild-type HIV and a panel of multi-PI resistant HIV-1 mutants containing clinically observed, primary mutations were identified using a cell-based assay. A number of PIs have been synthesized that show equivalent and greater activity for HIV-1 mutant strains as compared to wild-type HIV-1. The activity on the purified enzyme was confirmed for a selection of analogues.
