AzddMeC (CS-92) is an antiviral nucleoside analogue and a potent potent, selective and orally active HIV-1 reverse transcriptase and HIV-1 replication inhibitor. In HIV-1-infected human PBM cells and HIV-1-infected human macrophages, the EC50 values of AzddMeC are 9 nM and 6 nM, respectively.

How to use

In Vitro:

AzddMeC (CS-92) is also effective against HIV-2 in lymphocytes. The replication of Friend murine virus is only weakly inhibited, and no effect is observed against HSV type 1 and type 2 and coxsackievirus B4. The interaction of the 5'-triphosphate of AzddMeC with HIV-1 reverse transcriptase indicated competitive inhibition (the inhibition constant, Kis, is 9.3 nM).

In Vivo:

The pharmacokinetics of AzddMeC are characterized following intravenous and oral administration of 60 mg/kg of the compound to male rhesus monkeys. 3'-azido-3'-deoxythymidine (AZT) is a major metabolite of AzddMeC in monkeys. AzddMeC concentrations in serum declined rapidly in a biexponential fashion with the terminal half-life ranging from 0.5 to 1.3 hr. Renal excretion of unchanged nucleoside and metabolic deamination yielding AZT are the primary routes of AzddMeC clearance. The oral bioavailability is 26%.
