Cholic acid 7-sulfate is a metabolite of the primary bile acid cholic acid.[1],[2] It is produced by conjugation of a sulfate group with the hydroxy group at position 7 of cholic acid in the liver and gut. Fecal levels of cholic acid 7-sulfate are increased in male, but not female, mice fed a diet supplemented with cholic acid or chenodeoxycholic acid.[2]
Cholic acid anilide is a synthetic bile acid and derivative of cholic acid that inhibits the germination of C. difficile strain R20291 spores in vitro (IC50 = 1.8 μM).1 |1.
