    identified as potential leads for the treatment of diseases related to colon inflammation such as Crohn's and ulcerative colitis. In this paper, we report the discovery of a small library of hyodeoxycholane analogues, decorated at C-6 with different substituents, as potent and selective GPBAR1 agonists. In vitro pharmacological assays showed that compound 6 selectively activates GPBAR1 (EC50 = 0.3 μM) and reduces
    GPBAR1激动剂已被确定为治疗与结肠炎症相关的疾病(如克罗恩氏病和溃疡性结肠炎)的潜在先导。在本文中,我们报告了一个小片段的猪去氧胆碱类似物的发现,该类似物在C-6处修饰有不同的取代基,作为强效和选择性GPBAR1激动剂。体外药理分析表明,化合物6在THP1细胞中选择性激活GPBAR1(EC50 = 0.3μM)并减少促炎性细胞因子(IL-1β,IL-6和TNF-α)的产生。通过对接计算阐明了化合物6在GPBAR1中的结合模式。此外,化合物6在Gpbar1 + / +啮齿动物模型中预防TNBS诱导的结肠炎,代表了治疗这些炎症性疾病的诱人先机。

    Bile acid amides and oxazolines were synthesized by a sequence of steps involving the reaction of the free bile acid with formic acid to yield the formyloxy derivative, preparation of the formyloxy acid chloride, condensation of the acid chloride with 2-amino-2-methyl-1-propanol to give the amide and, finally, cyclization of the amide with thionyl chloride to give the oxazoline. The oxazolines were

    enhanced by the presence of bile acid substituents in the bisphosphonate framework, with no toxic effects. A straightforward synthesis of bile acid-containing hydroxy-bisphosphonates and a full characterization of these pharmaceutically important molecules, including an evaluation of affinity and the mechanism of binding to hydroxyapatite, is presented. The biological activity of bile acid-containing bisphosphonate
    现在,双膦酸盐(BPs)是用于与骨吸收增加有关的疾病(例如骨质疏松症和肿瘤性骨病)的最广泛使用的药物。BP的一个显着缺点是口服吸收差,双膦酸盐骨架中胆汁酸取代基的存在会增强它们的口服吸收,而没有毒性作用。提出了含胆汁酸的羟基双膦酸酯的直接合成方法和这些药学上重要分子的完整表征,包括亲和力评估和与羟基磷灰石的结合机理。使用中性红测定法在L929细胞系和破骨细胞的原代培养物中测定了含胆汁酸的双膦酸盐的生物活性。发现新化合物的生物活性优于已确定活性的双膦酸酯。
  • Chemical synthesis of 3β-sulfooxy-7β-hydroxy-24-nor-5-cholenoic acid: An internal standard for mass spectrometric analysis of the abnormal Δ5-bile acids occurring in Niemann-Pick disease

    In Niemann-Pick disease, type C1, increased amounts of 3 beta,7 beta-dihydroxy-5-cholenoic acid are reported to be present in urinary bile acids. The compound occurs as a tri-conjugate, sulfated at C-3, N-acetylglucosamidated at C-7, and N-acylamidated with taurine or glycine at C-24. For sensitive LC-MS/MS analysis of this bile acid, a suitable internal standard is needed. We report here the synthesis of a satisfactory internal standard, 3 beta-sulfooxy-7 beta-hydroxy-24-nor-5-cholenoic acid (as the disodium salt). The key reactions involved were (1) the so-called "second order" Beckmann rearrangement (one-carbon degradation at C-24) of hyodeoxycholic acid (HDCA) 3,6-diformate with sodium nitrite in a mixture of trifluoroacetic anhydride and trifluoroacetic acid, (2) simultaneous inversion at C-3 and elimination at C-6 of the ditosylate derivatives of the resulting 3 alpha,6 alpha-dihydroxy-24-nor-5 beta-cholanoic acid with potassium acetate in aqueous N,N-dimethylformamide, and (3) regioselective sulfation at C-3 of an intermediary 3 beta,7 beta-dihydroxy-24-nor-Delta(5) derivative using sulfur trioxide-trimethylamine complex. Overall yield of the desired compound was 1.8% in 12 steps from HDCA. (C) 2009 Elsevier Inc. All rights reserved.
