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[1][2]. AzddMeC is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
