β¦ Synopsis
New templates were designed and prepared which straddle the active site of HIV-1 protease. These templates were designed to be 'flexible scaffolds' upon which substituents could be appended to fill the pockets of HIV protease. The new templates prepared and analysed were 4-hydroxy-5H-furan-2-ones, 4-hydroxy-5,6-dihydropyrones, 3-hydroxy-cyclohex-2-enones, and 4-hydroxy-2(lH)-pyridinones, of which the 4-hydroxy-5,6-dihydropyrones were found to be the most potent inhibitors of HIV-1 protease.

Six models of the catalytic site of HIV-1 protease complexed with a reduced peptide inhibitor, MVT-101, were investigated. These studies focused on the details of protonation of the active site, its total net charge and hydrogen bonding pattern, which was consistent with both the observed coplanar c
We report the development of a simple, economical and reliable chromatographic method for the simultaneous determination of six HIV protease inhibitors (PIs; amprenavir, indinavir, lopinavir, nelfinavir, ritonavir and saquinavir), the active metabolite of nelfinavir (M8) and the non-nucleoside rever
