Methyl cholate

Kundenbewertung

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.

In Vitro

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].

Zebrafish larvae (2 days post-fertilization)^[2]
Dosage:

6.25 μM, 12.5 μM, 25 μM
Administration:

aqueous immersion; post 3 days of TAA exposure

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
