Biological target:
Merimepodib (VX-497) is a noncompetitive and oral inhibitor of inosine monophosphate dehydrogenase (IMPDH) with broad spectrum antiviral activities.
In vitro activity:
VX-497 is most potent against the first group of viruses, which includes HBV, HCMV, EMCV, and RSV, with 50% inhibitory concentrations (IC50s) of 0.38, 0.80, 1.0, and 1.14 μM, respectively. VX-497 has intermediate antiviral activity against a second group of viruses, which includes HSV-1, parainfluenza-3 virus, BVDV, VEEV, and dengue virus, with IC50s ranging from 6 to 19 μM. VX497 did not demonstrate antiviral efficacy against the third group of viruses, as measured by its inability to achieve an IC50 measurement for YFV, coxsackie B3 virus, or influenza A virus at 31 μM, the highest concentration tested. Next, whether VX-497 has any direct or indirect effect on the IFN-α signaling pathway was determined. To this end L929 cells and EMCV-infected L929 cells were treated with IFN-α alone and with IFN-α supplemented with VX-497. No noticeable difference in pattern or intensity of gelretarded bands (data not shown) was observed when the experiments were repeated with the addition of VX-497 (range, 100 to 500 nM). This suggests that VX-497 does not alter, positively or negatively, the IFN-α signaling pathway in L929 cells and that the antiviral effect of VX-497 in the EMCV replication system is indeed independent.

In vivo activity:
In the skin transplant study, trunk skin grafts from Balb/c mice were grafted onto C57Bl/6 mice. Mice were administered vehicle or VX-497 twice daily until day 10. Mean survival of skin grafts on vehicle-treated animals was 9.9 +/- 0.9 days. Graft survival was prolonged significantly in animals treated with VX-497 to 13.2 +/- 1.2 (p < 0.001, Kaplan Meier Log-Rank test) days in the 50 mg/kg group and 13.9 +/- 1.0 (p < 0.001) days in the 85 mg/kg group. In the GVHD study, 150 x 10(6) nonadherent splenocytes from B6 mice were injected intravenously into the F1 hybrid strain B6DBA/2. Groups of animals (n = 6) were administered vehicle or 50 or 100 mg/kg VX-497 b.i.d for 8 days. GVHD developed in the vehicle-treated allografted F1 mice and treatment with VX-497 improved all manifestations of the disease significantly. The 2.9-fold increase in spleen weight in allografted animals was reduced to a 1.6-fold increase in the VX-497-treated mice. Serum IFN-gamma levels were increased 54-fold in the vehicle group while there was a 7.4-fold increase in VX-497-treated animals. Spontaneous spleen cell proliferation was increased 9.9-fold in the absence of VX-497 and there was a 3.5-fold increase in its presence. Thus, VX-497 has been shown to be effective in both a skin transplantation and a GVHD model in the mouse. The demonstrated pharmacological activity of VX-497 in these murine transplantation models warrants further evaluation of the drug in transplantation indications.
