FNC-TP 是 FNC 的细胞内活性形式。FNC 是一种有效的核苷逆转录酶抑制剂 (NRTI)，对 HIV、HBV 和 HCV 具有抗病毒活性。
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 (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].
