Cn. Hodge et al., STUDIES ON ORALLY AVAILABLE INHIBITORS OF HIV PROTEASE - PEPTIDYL ALDEHYDES AND TRIFLUOROMETHYL KETONES, Antiviral chemistry & chemotherapy, 5(4), 1994, pp. 257-262
Low-molecular-weight peptidyl aldehyde inhibitors of HIV protease that
reach in vivo plasma concentrations after oral administration substan
tially in excess of the antiviral IC90 are described. We also report e
fforts to improve the potency and stability of these compounds that cu
lminated in a series of peptidyl trifluoromethyl ketones with increase
d potency but decreased bioavailability.
