Atazanavir Sulfate (also known as Latazanavir, Zrivada, Reyataz, BMS-232632), the sulfate salt form of atazanavir, is a HIV protease inhibitor (PI) for HIV/AIDs treatment with Ki of 2.66 nM in a cell-free assay. The treatment for HIV/AIDS is the same as that of other antiretrovirals. Since it can be given once daily and has less of an impact on the patient's lipid profile than other PIs, atazanavir stands apart from the others. It is used exclusively in conjunction with other HIV medications, similar to other protease inhibitors.

ln Vitro |
Atazanavir has an IC50 of approximately 47 nM for the proteolytic cleavage of the viral gag precursor p55 polyprotein in H9 cells infected with the virus. With an EC50 of 3.89 nM in RF/MT-2 strains, atazanavir demonstrates strong antiviral activity.[1] It is demonstrated that atazanavir inhibits bilirubin glucuronidation with an IC50 of 2.4 μM. Atazanavir has a Ki of 1.9 μM, which inhibits recombinant UGT1A1.[2] In U251, T98G, and LN229 glioblastoma cell lines, atazanavir inhibits cell growth with notably elevated levels of GRP78 and CHOP protein. In U251 glioblastoma cells, atazanavir induces a significant upregulation of polyubiquitinated proteins of diverse sizes.[3] With an IC50 of 26 μM, atazanavir also inhibits the human 20S proteasome. In HepG2 cells, atazanavir (30 μM) modifies the levels of ER stress and UPR gene expression.[4] In LS180V cells, atazanavir (30 mM) results in a 2.5-fold increase in immunoreactive P-gp expression and a decrease in intracellular Rh123.[5]

Enzyme Assay |
Purified HIV-1 RF wild-type Prt (2.5 nM) is incubated at 37 °C 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) with or without atazanavir in order to calculate the inhibition constants (Ki) for each Prt inhibitor. Using a Cytofluor 4000, cleavage of the substrate is measured as an increase in fluorescent emission at 490 nM following excitation at 340 nM. In five different concentrations of Atazanavir (1.25 nM to 25 nM), reactions are conducted with substrate that is 1.36 μM, 1.66 μM, 2.1 μM, 3.0 μM, 5.0 μM, or 15 μM. During a half-hour, the substrate cleavage is observed every five minutes. Then, at early stages of the reaction, cleavage rates are calculated for each sample, and Ki values are ascertained from the slopes of the ensuing Michaelis-Menten plots.

Cell Assay |
In order to assess cytotoxicity, host cells are cultured for six days with serially diluted Atazanavir. Cell viability is then measured using the XTT[2,3-bis(2-methoxy-4-nitro-5-sulfophenyl-2H-tetrazolium-5-carboxanilide)] assay, which yields the 50% cytotoxic concentrations (CC50s). In order to evaluate how human serum proteins affect antiviral activity, 40% adult human serum or 1 mg of α1-acid glycoprotein/mL is added to the 10% fetal calf serum that is typically used for assays.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
