Methyl cholate
Based on 1 Customer Validation
Methyl cholate is a bile acid analog and a specific inhibitor of TcdB toxin from Clostridioides difficile. Methyl cholate exerts a stronger selective inhibitory effect on TcdB than on TcdA. Methyl cholate induces conformational stabilization by binding to a unique site of TcdB, thereby blocking the binding of the toxin to host receptors and its self-processing process. Methyl cholate effectively protects human fibroblasts from TcdB-induced cytopathic effects. Methyl cholate exhibits dose-dependent anti-hepatic fibrosis activity in both cellular and zebrafish models, and significantly reduces the expression levels of α-SMA and COL-I. Methyl cholate is suitable for in-depth research in the fields of Clostridioides difficile infection and hepatic fibrosis.

Biological Activity
Methyl cholate (0.1-100 μM; 10 min pre-incubation, 3.5 hr combined exposure) dose-dependently protects human IMR-90 fibroblasts from TcdB-induced cell rounding with an IC50 of 11 μM, but does not protect against TcdA-induced cell rounding[1].
Methyl cholate (0.8-200 μM; 30 min pre-incubation, 3 hr reaction) dose-dependently inhibits IP6-induced autoprocessing of full-length Clostridium difficile TcdB, but does not affect autoprocessing of the isolated GTD-CPD truncated construct[1].
Methyl cholate (40 μM; 45 min pre-incubation with TcdB, 45 min incubation with cells) potently inhibits Clostridium difficile TcdB binding to Vero cells, reducing bound toxin to ~10% of vehicle control levels[1].
Methyl cholate (0.1-100 μM; 3 hr combined exposure) dose-dependently protects human IMR-90 fibroblasts from TcdB-induced necrosis with an IC50 of 4.3 μM[1].
Methyl cholate (80.64 μg/mL; 48 h) inhibits HSC-T6 hepatic stellate cell proliferation with an IC50 of 80.64 μg/mL after 48 h of incubation[2].
Methyl cholate (low to high dose range; duration sufficient to alter protein expression) dose-dependently reduces α-SMA protein expression, a marker of hepatic stellate cell activation, in HSC-T6 cells[2].
Methyl cholate (duration sufficient to alter protein expression) increases PIK3-α protein expression in HSC-T6 hepatic stellate cells[2].

-
Concentration:80.64 μg/mL
-
Incubation Time:48 h
-
Result:Inhibited HSC-T6 cell proliferation in a dose-dependent manner, with a calculated half-maximal inhibitory concentration (IC50) of 80.64 μg/mL after 48 h of treatment.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
