  Oxidative and reductive transformations of 11-keto-β-boswellic acid

  摘要：

  Extraction of frankincense-a fragrant resin obtained from plants of the genus Boswellia followed by an oxidation furnished high yields of (313) 3-O-acetyl-11-keto-beta-boswellic acid (beta-AKBA), a valuable starting material for accessing boswellic acid derivatives. Boswellic acids are fascinating triterpenoic acids that exhibit different biological activities. However, their biological potential, as well as that of their derivatives, remained unexploited due to their limited availability. In this study we were able to prepare derivatives of 11-keto-beta-boswellic acid in good to excellent yields by oxidative and reductive transformations mainly in rings A and C of the triterpenoid skeleton. Among other transformations, a highly cytotoxic endoperoxide was obtained in excellent yields. (C) 2015 Elsevier Ltd. All rights reserved.

  作为潜在抗 GBM 药物的新型乙酰基-11-酮-β-乳香酸衍生物的合成

  摘要：

  乙酰-11-酮-β-乳香酸 (AKBA) 已知可抑制胶质母细胞瘤 (GBM) 细胞和皮下 GBM 的生长。合成了一系列含有肟酯官能团或酰胺侧链的乙酰基-11-酮-β-乳香酸（AKBA）衍生物，并评估了它们的抗GBM活性。其中一些化合物对 U87 和 U251 GBM 细胞系中的细胞增殖表现出显着的抑制活性，IC 50值在微摩尔浓度范围内。细胞热位移分析表明A-01和A-10提高了FOXM1的热稳定性，表明这些高活性化合物可能直接与细胞内的FOXM1结合。对两种最活跃的化合物A-01和A-10的对接研究揭示了这些化合物与 FOXM1 活性位点之间的关键相互作用，其中 C-24 位点的酰胺部分对于提高活性至关重要。这些结果表明A-10是开发 FOXM1 抑制剂的合适先导分子。因此，合理设计具有酰胺侧链的AKBA衍生物对于发现一类能够抑制GBM细胞增殖的新型三萜类化合物具有巨大的潜力。

  mitosis A1) is a validated molecular target for anticancer drug discovery. Herein, we reported the design, synthesis, and structure-activity relationship study of novel ring A modified AKBA (3-acetyl-11-keto-boswellic acid) derivatives as Pin1 inhibitors. Most compounds showed superior Pin1 inhibitory activities to AKBA. One of the most promising compounds, 10a, potently inhibited Pin1 with IC50 value

  Pin1（蛋白质在有丝分裂A1中从未相互作用）是经过验证的抗癌药物分子靶标。在本文中，我们报道了作为Pin1抑制剂的新型A环修饰的AKBA（3-乙酰基-11-酮-乳香酸）衍生物的设计，合成和构效关系研究。大多数化合物显示出优于AKBA的Pin1抑制活性。最有前途的化合物之一10a可以有效地抑制Pin1，其IC 50值为0.46μM，而它对GI 50值为1.82μM的前列腺癌细胞PC-3表现出优异的抗增殖作用。结构-活性关系表明，环A中合理的结构修饰对改善活性具有重要影响。进一步的机理研究表明10a降低了PC-3癌细胞中Cyclin D1的水平并导致细胞周期停滞在G0 / G1期。因此，化合物10a可以作为潜在的抗前列腺癌药物，通过抑制Pin1进行进一步研究。

  Parent pentacyclic triterpenoic acids such as ursolic-, oleanolic, glycyrrhetinic, betulinic and boswellic acid were converted into their acetylated piperazinyl amides that were coupled with rhodamine B. SRB assays to evaluate their cytotoxicity showed all of these triterpene-homopiperazinyl-rhodamine adducts 16–20 being highly cytotoxic for a panel of human tumor cell lines even in nanomolar concentrations

  A new series of 11-keto-β-boswellic acid and 3-O-acetyl-11-keto-β-boswellic acid analogs (5, 7, 8, 10, 13, 18a-d, 27a-c, 28a-d) were synthesized by modification of hydroxyl and acid functional moieties of boswellic acids. The structures of these analogs were confirmed by spectral data analysis (1H, 13C NMR and mass). Compounds 18b, 27a and 8 showed potent 5-lipoxygenase enzyme inhibitory activity (IC50:

  一系列新的11-酮-β-乳香酸和3-O-乙酰基-11-酮-β-乳香酸类似物（5、7、8、10、13、18a-d，27a-c，28a-d ）是通过修饰乳香酸的羟基和酸官能部分合成的。这些类似物的结构通过光谱数据分析（1 H，13 C NMR和质量）确认。化合物18b，27a和8显示出有效的5-脂氧合酶抑制活性（IC50：19.53、20.31和44.14μg/ mL）。计算研究表明，AKBA的选择性是由于它适合5-LOX受体，而其他酶（如12-LOX，COX-1和COX-2）则缺少该受体。我们的研究发现2-甲酰基和3-酮取代基对恢复在第4位具有必需COOH基团的非活性AKBA类似物的增强作用。

  Boswellic acid acylates including their epimers were synthesized and screened against a panel of human cancer cell lines. They exhibited a range of cytotoxicity against various human cancer cell lines thereby leading to the development of a possible SAR. One of the identified lead compounds was found to be an inhibitor of the NF-kappa B and STAT proteins, warranting further investigations to be developed into a potential anticancer lead.
