Allolithocholic acid

Allolithocholic acid is used as steroid compound as T regulatory lymphocyte modulators and uses for treatment of inflammatory or autoimmune disorders.

ChEBI: Allolithocholic acid is a bile acid.

Allolithocholic acid is a secondary allomonohydroxy bile acid.1 It activates large-conductance calcium-activated potassium channels (BK/KCas; EC50 = 44.21 µM in Xenopus oocytes expressing the rat channel). Fecal levels of allolithocholic acid are increased in patients with colorectal cancer.2 Allolithocholic acid has also been found in the urine of infants with biliary atresia.3
