title: In vitro transformation of cheno- and ursodeoxycholic acids and their 7-oleyl esters by human intestinal microflora.
abstract: Chenodeoxycholic and ursodeoxycholic acid are used widely for the treatment of gallstones. A possible drawback to their utility is their conversion to lithocholic acid, which has displayed histotoxicity and mutagenicity. The 7-oleyl esters of cheno- and ursodeoxycholic acid are not degraded by fecal bacteria and may represent safer means of treatment.
