FNC-TP 

FNC-TP is the intracellular active form of FNC. FNC is a potent nucleoside reverse transcriptase inhibitor (NRTI), with antiviral activity on HIV, HBV and HCV^[1]. FNC-TP 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.

FNC (0.1-10 nM; 24-240 h) is found mainly to accumulate in these HIV-1 target cells, and the retention of FNC-TP is 2-4 times higher than in other types of cells^[1].

FNC (1-6 mg/kg; a single p.o.) could enter rhesus macaque PBMCs and form the active nucleoside triphosphate FNC-TP^[1].
