Amprenavir

Amprenavir is an human immunodeficiency virus (HIV) protease inhibitor with IC50 of 14.6 ?12.5 ng/ml for wild-type HIV isolates. Like all HIV protease inhibitors, amprenavir interrupts the maturation phase of the HIV replicative cycle by forming an inhibitor-enzyme complex, which prevents HIV protease from binding with its normal substrates. It has an enzyme inhibition constant (Ki = 0.6 nM) that falls within the Ki range of the other protease inhibitors.
