  摘要：

  摘要 α-和β-乳香酸中 C(3)、C(4)、C(5)、C(8)、C(10)、C(13) 和 C(17) 处的取代基构型有熊烷-齐墩果烷相互转化表明它们是相同的。C(3) 差向异构醇的合成和脱水研究证实了乳香酸中羟基的轴向配置，并表明参与组的共面性不一定是环收缩的基本要求。乳香酸的 C(3) 和 C(24) 二羟基衍生物的环化反应表明，环 A 可以很容易地从椅子变成船形，以允许反式双轴羟基的循环缩醛化。

• Acyl derivatives of boswellic acids as inhibitors of NF-κB and STATs

  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.

  4-Amino analogues prepared from beta-boswellic acid and 11-keto-beta-boswellic acid, wherein the carboxyl group in ursane nucleus was replaced by an amino function via Curtius reaction, displayed improved cytotoxicity than the parent molecules. The same molecules also exhibited apoptotic activity by inducing DNA fragmentation. (c) 2007 Elsevier Ltd. All rights reserved.

  A series of beta-boswellic acid derivatives were synthesized and evaluated for anticancer activity. One of the lead analog 4f displayed significant anticancer activity against a panel of cancer cells as well as substantially inhibited colony formation in HCT-116 cells. Furthermore, 4f was found to be a potent inducer of apoptosis confirmed by loss of mitochondrial membrane potential, DAPI staining, Western blotting and ROS generation. (C) 2015 Elsevier Ltd.
