Mechanism of Action

Targets/IC₅₀/Ki	HIV protease
In vitro	Atazanavir has potent in vitro activity with 50 and 90% effective concentrations(EC50) of 2-5 nM and 9-15 nM respectively against wild type virus. This compound is able to potently induce endoplasmic reticulum (ER) stress response in malignant glioma cells, as indicated by elevated levels of GRP78 and CHOP, and activation of caspase-4, which leads to cell death.
In vivo	Atazanavir has excellent oral bioavailability in the range of 60-70%.
