Biological Activity

Atazanavir sulfate (BMS-232632, Reyataz) is a sulfate salt form of atazanavir (BMS-232632) that is an highly potent HIV protease inhibitor with EC50 and EC90 of 2.6~5.3 nM and 9~15 nM in cell culture. Atazanavir (BMS-232632) blocks the cleavage of viral precursor proteins in HIV-infected cells. Atazanavir (BMS-232632) is generally more potent than the five currently approved HIV-1 Prt inhibitors. Furthermore, Atazanavir (BMS-232632) is highly selective for HIV-1 Prt and exhibits cytotoxicity only at concentrations 6,500- to 23, 000-fold higher than that required for anti-HIV activity.

Cell Experiment
Cell lines MT-2 and CEM-SS cells, monocytes/macrophages, and PBMCs
Preparation method To determine cytotoxicity, host cells were incubated in the presence of serially diluted inhibitors for 6 days and cell viability was quantitated using an XTT [2,3-bis(2-methoxy-4-nitro-5-sulfophenyl-2H-tetrazolium-5-carboxanilide] assay to calculate the 50% cytotoxic concentrations (CC50s) (42). To assess the effect of human serum proteins on antiviral activity, the 10% fetal calf serum normally used for assays was replaced with 40% adult human serum (Sigma) or 1 mg of α1-acid glycoprotein (Sigma)/ml.
Concentrations 0~100 μM
Incubation time 6 days
Animal Experiment
Animal models male Wistar rats model
Formulation 50% ethanol-50% normal saline
Dosages 80mg/kg/min
Administration constant intravenous infusion
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
