The synthesis of 19-hydroxylated bile acids (3α, 19-dihydroxy-, 3α, 7α, 19-trihydroxy-, 3α, 12α, 19-trihydroxy-and 3α, 7α, 12α, 19-tetrahydroxy-5β-cholan-24-oic acids) was described. These synthesized 19-hydroxylated bile acids were used as standard samples for the analysis of bile acids in human urine by gas chromatography-mass spectrometry. 3α, 7α, 12α, 19-Tetrahydroxy-5β-cholan-24-oic acid was identified in neonatal urines (0.1-1.5 μg/ml and 1.5-7% of total bile acids).
介绍了 19-羟基化胆汁酸(3α,19-二羟基,3α,7α,19-三羟基,3α,12α,19-三羟基和 3α,7α,12α,19-四羟基-5β-胆烷-24-酸)的合成。这些合成的 19- 羟基胆汁酸被用作标准样品,通过气相色谱-质谱法分析人体尿液中的胆汁酸。在新生儿尿液中发现了 3α、7α、12α、19-四羟基-5β-胆烷-24-酸(0.1-1.5 μg/ml,占胆汁酸总量的 1.5-7%)。
