Atazanavir是一种高选择性的HIV-1蛋白酶抑制剂，可研究艾滋病毒感染。它也是SARS-CoV 3CLpro的抑制剂，IC50为 3.49 μM。它是CYP3A4的底物和抑制剂，也是P-糖蛋白的抑制剂和诱导剂。

Atazanavir(BMS-232632) is an highly effective HIV-1 protease inhibitor.

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[1]. Atazanavir 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[3].

Atazanavir has excellent oral bioavailability in the range of 60-70%[1].

Protease assays: To determine the inhibition constants (Ki) for each Prt inhibitor, purified HIV-1 RF wild-type Prt (2.5 nM) is incubated at 37 ℃ with 1 μM to 15 μM fluorogenic substrate in reaction buffer (1 M NaCl, 1 mM EDTA, 0.1 M sodium acetate [pH 5.5], 0.1% polyethylene glycol 8000) in the presence or absence of Atazanavir. Cleavage of the substrate is quantified by measuring an increase in fluorescent emission at 490 nM after excitation at 340 nM using a Cytofluor 4000. Reactions are carried out using 1.36 μM, 1.66 μM, 2.1 μM, 3.0 μM, 5.0 μM, or 15 μM substrate in the presence of five concentrations of Atazanavir (1.25 nM to 25 nM). Substrate cleavage is monitored at 5-min intervals for 30 min. Cleavage rates are then determined for each sample at early time points in the reaction, and Ki values are determined from the slopes of the resulting Michaelis-Menten plots.

U251, T98 g, and LN229 glioblastoma cell lines are exposed to increasing concentrations of nelfinavir and atazanavir. Cells cultured in 96-well plates are treated with drugs for 48 h, and cell growth and survival are determined by conventional MTT assay.(Only for Reference)
