Modified bile acids: preparation of 7α,12α-dihydroxy-3β- and 7α,12α-dihydroxy-3α-(2-hydroxyethoxy)-5β-cholanic acid and their biological activity
摘要:
Methodology for the preparation of 7-alpha,12-alpha-dihydroxy-3-beta- (2) and 7-alpha,12-alpha-dihydroxy-3-alpha-(2-hydroxyethoxy)-5-beta-cholanic acid (3) is described. Nucleophilic displacement of the 3-mesylate of unprotected cholic acid with ethylene glycol led to the 3-beta-isomer whereas the 3-alpha-isomer was synthesized via the 7,12-diacetyl protected 3-allyl ether of methyl cholate. Only the 3-alpha-isomer 3 is recognized by the ileal bile acid transport system with affinity comparable to cholic acid.
