| Abstract
| - Starting from the chemical structure of the recent FDA-approved anti-HIV drug Amprenavir(Agenerase), a potent HIV-protease inhibitor, we have designed new series of Amprenavirbioisoteres in which the methylene group of the benzyl group was replaced by a sulfur atom.This structural modification has required an original multistep synthesis. Unfortunately,introduction of the sulfur atom abolished or drastically decreased both inhibitory activity onrecombinant HIV protease and HIV infection protection on MT4 cell cultures.
