Tenofovir exalidex是一种非环核苷酸类似物 Tenofovir 的脂质结合物，对野生型和抗逆转录病毒耐药的 HIV 毒株，包括多药核苷/核苷酸类似物耐药病毒，都有活性。Tenofovir exalidex 对人外周血单个核细胞中所有主要的HIV-1和HIV-2亚型以及单核细胞来源的巨噬细胞中所有 HIV-1 菌株具有活性，EC50 范围在 0.2 和 7.2 nM 之间。Tenofovir exalidex 具有口服活性，无明显毒性。Tenofovir exalidex 对 HBV 也有活性。

Tenofovir exalidex is a lipid conjugate of the acyclic nucleotide analog Tenofovir with activity against both wild-type and antiretroviral drug-resistant HIV strains, including multidrug nucleoside/nucleotide analog-resistant viruses. Tenofovir exalidex is active against all major subtypes of HIV-1 and HIV-2 in fresh human PBMCs and against all HIV-1 strains evaluated in monocyte-derived macrophages, with EC50s ranging between 0.2 and 7.2 nM. CMX157 is orally available and has no apparent toxicity. Tenofovir exalidex also shows antiviral activity against HBV.

Tenofovir exalidex is consistently >300-fold more active than Tenofovir against multiple viruses in several different cell systems. Tenofovir exalidex will be effective against MNR mutants, including those that are unresponsive to all currently available NRTIs. Notably, the average EC50 in PBMCs for CMX157 against a panel of 27 wild-type HIV-1 isolates representing group M subtypes A to G and group O was 2.6 nM (range, 0.2 to 7.2 nM)[1]. Tenofovir exalidex exerts its therapeutic actions by inhibiting HBV polymerase-mediated HBV DNA elongation, but there is no known binding of cyclophilins to HBV polymerase nor participation of cyclophilins in DNA elongation. The combinational effect of CRV431 (host-targeting) and Tenofovir exalidex (direct-acting) on HBV DNA production is more consistent with the two compounds acting on distinct steps of the HBV life cycle[3].

Tenofovir exalidex (Sprague-Dawley rats) is orally available and has no apparent toxicity when given orally to rats for 7 days at doses of 10, 30, or 100 mg/kg/day[2]. Tenofovir exalidex (5-10 mg/kg; oral gavage; daily for a period of 16 days) decreases liver HBV DNA levels dose-dependently[3].
