  Synthesis and in vitro cholesterol dissolution by 23- and 24-phosphonobile acids

  摘要：

  A new class of 23- and 24-phosphonobile acids have been synthesized from bile acid and their in vitro cholesterol-dissolving efficiency have been estimated. 24-Phosphonobile salts (PBSs) are slightly more efficient in solubilizing cholesterol than 23-PBSs and natural bile salts. The cholesterol solubilizing power is influenced by the structure of PBSs, and is considerably reduced with an increase in the bulk pH. ((c) 2005 Elsevier Inc. All rights reserved.
