Atazanavir

Synonyms: Latazanavir, Zrivada, Reyataz, BMS-232632

Atazanavir (Latazanavir, Zrivada, Reyataz, BMS-232632) is an azapeptide and HIV-protease inhibitor that is used in the treatment of HIV infections and AIDS in combination with other anti-HIV agents. Atazanavir is a substrate and inhibitor of cytochrome P450 isozyme 3A (CYP3A4) and an inhibitor and inducer of P-glycoprotein.

Biological Activity

Description Atazanavir (Latazanavir, Zrivada, Reyataz, BMS-232632) is an azapeptide and HIV-protease inhibitor that is used in the treatment of HIV infections and AIDS in combination with other anti-HIV agents. Atazanavir is a substrate and inhibitor of cytochrome P450 isozyme 3A (CYP3A4) and an inhibitor and inducer of P-glycoprotein.
Targets
HIV protease [1]
In vitro
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[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].
Cell Research Cell lines The malignant glioma cell lines U251, LN229 and T98G
Concentrations 0-100 μM
Incubation Time 48 h
Method U251, T98G, 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.
In Vivo
In vivo Atazanavir has excellent oral bioavailability in the range of 60-70%[1].
Animal Research Animal Models The WT mice (FVB/NTac strain), TKO mice (FVB/N7 strain)
Dosages 10 mg/kg

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
