Validation of [22,23-3H]cholic acid as a stable tracer through conversion to deoxycholic acid in human subjects

Autor: W C Duane, C D Schteingart, H T Ton-Nu, A F Hofmann

Publikováno v: Journal of Lipid Research, Vol 37, Iss 2, Pp 431-436 (1996)

Bile acids labeled with 3H on the sterol nucleus lose a substantial fraction of label during enterohepatic cycling and conversion to secondary bile acids. We tested the isotopic stability of a side-chain 3H label, [22,23-3H]cholic acid in humans. The

Publikováno v: Journal of Lipid Research, Vol 37, Iss 1, Pp 98-112 (1996)

The hepatic biotransformation in the rat and hamster of 23(R)-hydroxychenodeoxycholic acid (23(R)OH-CDCA), the alpha-hydroxy derivative of CDCA, was defined; some physiological and physicochemical properties were also assessed. 23(R)OH-CDCA was isola

Effects of side chain length on ionization behavior and transbilayer transport of unconjugated dihydroxy bile acids: a comparison of nor-chenodeoxycholic acid and chenodeoxycholic acid.

Autor: J Ko, J A Hamilton, H T Ton-Nu, C D Schteingart, A F Hofmann, D M Small

Publikováno v: Journal of Lipid Research, Vol 35, Iss 5, Pp 883-892 (1994)

13C-NMR spectroscopy was used to examine the effect of side chain length on the ionization properties and transmembrane transport rate of 3 alpha,7 alpha-dihydroxy bile acids. When solubilized in taurocholate micelles, [23-13C]nor-chenodeoxycholic ac

Synthesis of 24-nor-5 beta-cholan-23-oic acid derivatives: a convenient and efficient one-carbon degradation of the side chain of natural bile acids

Autor: C D Schteingart, A F Hofmann

Publikováno v: Journal of Lipid Research, Vol 29, Iss 10, Pp 1387-1395 (1988)

An efficient procedure for obtaining nor-bile acids from natural (C24) bile acids is described. Treatment of formylated bile acids with sodium nitrite in a mixture of trifluoroacetic anhydride with trifluoroacetic acid gives, through a ''second order

Intestinal absorption and enterohepatic cycling of biliary iron originating from plasma non-transferrin-bound iron in rats

Autor: C D Schteingart, Pierre Brissot, U Bolder, A F Hofmann, J Arnaud

Publikováno v: Hepatology. 25:1457-1461

In iron overload, non-transferrin-bound iron (NTBI) is found in plasma and is rapidly removed by hepatocytes. Some of this NTBI is excreted into bile. Biliary excretion of NTBI, in the form of an iron- deferiprone chelate, is greatly increased by def
