Tenofovir exalidex (CMX157) 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.

In Vitro

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].

In Vivo

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].

Animal Model:	Female transgenic mice HBV transgenic Tg05 mice (C57BL/6)^[1]
Dosage:	5 mg/kg, 10 mg/kg
Administration:	Oral gavage; daily for a period of 16 days
Result:	The reductions in HBV DNA were 55% and 97% for low-dose (5 mg/kg/day) and high-dose (10 mg/kg/day), respectively.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2 mg/mL (3.51 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
