  齐墩果酸衍生物作为蛋白质酪氨酸磷酸酶1B抑制剂的合成及生物学评价

  摘要：

  蛋白酪氨酸磷酸酶1B（PTP1B）是胰岛素信号传导过程中的负调节剂，是糖尿病和肥胖症的有希望的药物靶标。合成齐墩果酸的衍生物并评价为PTP1B抑制剂。几种衍生物对PTP1B表现出中等至良好的抑制活性，其中25f表现出最有希望的抑制作用（IC 50 = 3.12μM）。这些衍生物的结构活性关系分析表明，A环和12-烯部分的完整性在保留PTP1B酶抑制活性中很重要。此外，亲水和酸性基团以及齐墩烯与酸部分之间的距离与PTP1B抑制活性有关。25f的可能绑定模式 通过分子对接模拟进行了探索。

• Practical Partial Synthesis of Myriceric Acid A, an Endothelin Receptor Antagonist, from Oleanolic Acid

  日期：1997.2.1

  Myriceric acid A (1) is an oleanane triterpene that is a potent and specific endothelin A receptor antagonist. A practical procedure for large-scale synthesis of myriceric acid A (1) has been developed starting from oleanolic acid 4. The conversion of oleanolic acid 4 to the key intermediate myricerone 3 was achieved in an efficient manner employing a photochemical reaction (the Barton reaction) of nitrite 7. Our synthetic procedure alleviated several difficulties of the original Barton's procedure with regard to yields and large-scale operation. Myricerone 3 afforded Horner-Wadsworth-Emmons (HWE) type phosphonate 2 which has proved to be a versatile precursor of 1. The preparation of phosphonate 2 on a scale of several hundred grams is described. The synthesis was completed by condensation of 2 with 3,4-bis[(diphenylmethyl)oxy]benzaldehyde (21), giving alpha,beta-unsaturated ester 22, which was deprotected to afford 1. The whole synthetic sequence is efficient (14 steps, 31% yield) and requires no chromatographic purification except to obtain the final product 1.

  The triterpene oleanolic acid 1 and its semisynthetic derivatives 2-7 were assessed for gastroprotective and ulcer-healing effect using human epithelial gastric cells (AGS) and human lung fibroblasts (MRC-5). The ability of the compounds to protect the AGS cells against the damage induced by sodium taurocholate (NaT), to stimulate the cellular reduced glutathione (GSH) and prostaglandin E-2 content, to enhance AGS and MRC-5 cell proliferation and to scavenge superoxide anion in vitro was studied. The cytotoxicity of the compounds was assessed towards MRC-5 and AGS cells. In addition, the gastroprotective activity of the compounds was assessed in vivo using the HCl/EtOH-induced ulcer model in mice. All the assayed compounds displayed a significant reduction of AGS cells damage after incubation with NaT. None of the studied compounds was active as a superoxide anion scavenger nor stimulated the GSH content in AGS, cell cultures. Compounds 1, 2, 4 and 6 were able to increase the prostaglandin content in AGS cell cultures. Concerning the proliferation assays, a significant stimulating effect was observed for compounds 3 and 7 on AGS cells and for 1 and 7 on MRC-5 fibroblasts. Regarding cytotoxicity, derivatives 2, 4, 6 and 7 were less toxic than the parent compound oleanolic acid. Our results strongly support the predictive capacity of the in vitro assessment of gastroprotective activity allowing the reduction of experimental animals. (c) 2006 Elsevier Inc.
