  Novel 18β-glycyrrhetinic acid analogues as potent and selective inhibitors of 11β-hydroxysteroid dehydrogenases

  摘要：

  Extensive structural modifications to the 18beta-glycyrrhetinic acid template are described and their effects on the SAR of the 11beta-hydroxysteroid dehydrogenase isozymes type 1 and 2 from the rat are investigated. Isoform selective inhibitors have been discovered and compound 7 N-(2-hydroxyethyl)-3beta-hydroxy-11-oxo-18beta-olean-12-en-30-oic acid amide is highlighted as a very potent selective inhibitor of 11beta-hydroxysteroid dehydrogenase 2 with an IC50 = 4 pM.

  main active compound in liquorice root. Its aglycone, glycyrrhetinic acid, has shown several beneficial pharmacological activities. This study reports the synthesis and screening of a series of glycyrrhetinic acid analogs as AChE-Is. Fourteen derivatives were prepared, of which five derivatives are recorded as new viz., 3-phenyl-carbamoyl-18β-glycyrrhetinic acid (J9), 3-acetyl-18β-glycyrrhetinic-30-anilinamide

  乙酰胆碱酯酶抑制剂（AChE-Is）可增加乙酰胆碱（ACh）的作用水平和作用持续时间；因此，减轻了阿尔茨海默氏病（AD）的症状。甘草甜素是甘草根中的主要活性化合物。它的糖苷配基，甘草次酸显示出几种有益的药理活性。该研究报告了一系列甘草次酸类似物AChE-Is的合成和筛选。制备了十四个衍生物，其中五个衍生物被记录为新的，即3-苯基氨基甲酰基-18β-甘草次酸（J9），3-乙酰基-18β-甘草次酸-30-苯胺（J10），3-乙酰基-18β -甘草次酸30-乙醇酰胺（J11），3-乙酰基18β-甘草次酸30-正丁酰胺（J12）和18β-甘草次酸30-异戊二烯酯（J14），以及九种已知衍生物（J1 - J8和J13）。化合物J12，J11，J0和J3表现出显着的AChE-1活性，IC 50值分别为3.43、5.39、6.27和8.68μM。这些结果与对接研究完全一致。活性化合物对正常细胞（WI-38）无细胞毒性。

  Triterpenoic acids show many pharmacological effects, among them an antiinflammatory or an antitumor activity. One of these, glycyrrhetinic acid (1) is of interest because of its antitumor profile. Glycyrrhetinic acid is not only cytotoxic but also triggers apoptosis in various human tumor cell lines. To improve the cytotoxicity of parent 1 we set out to synthesize new derivatives of it-differing in structure and lipophilicity. These compounds were tested in a sulforhodamine B assay for cytotoxicity, and screened for their ability to induce apoptosis using an acridine orange/ethidium bromide assay and trypan blue staining. The most active compound, 34, a benzyl glycyrrhetinate holding an extra 3-N-(3-aminopropyl)glycyl substituent showed IC50 between 1.96 and 5.14 mu m for five human cancer cell lines and triggers apoptosis in 80% of the cells.
