  Synthesis and induction of apoptosis signaling pathway of ent-kaurane derivatives

  摘要：

  Thirty one ent-kaurane derivatives were prepared from kaurenoic acid (1), grandiflorenic acid (16), 15 alpha-acetoxykaurenoic acid (26) and 16 alpha-hydroxy-kaurenoic acid (31). They were tested for their ability to inhibit cell viability in the mouse leukemic macrophagic RAW 264.7 cell line. The most effective compounds were 12, 20, 21, and 23. These were selected for further evaluation in other human cancer cell lines such as Hela, HepG2, and HT-29. Similar effects were obtained although RAW 264.7 cells were more sensitive. In addition, these compounds were significantly less cytotoxic in non-transformed cells. The apoptotic potential of the most active compounds was investigated and they were able to induce apoptosis with compound 12 being the best inducer. The caspase-3, -8 and -9 activities were measured. The results obtained showed that compounds 12, 21, and 23 induce apoptosis via the activation of caspase-8, whereas compound 20 induces apoptosis via caspase-9. Immunoblot analysis of the expression of p53, Bax, Bcl-2, Bcl-xl, and IAPs in RAW 264.7 cells was also carried out. When cells were exposed to 5 mu M of the different compounds, expression levels of p53 and Bax increased whereas levels of antiapoptotic proteins such as Bc1-2, Bc1-x1, and IAPs decreased. In conclusion, kaurane derivatives (12, 20, 21, and 23) induce apoptosis via both the mitochondrial and membrane death receptor pathways, involving the Bcl-2 family proteins. Taken together these results provide a role of kaurane derivatives as apoptotic inducers in tumor cells. (C) 2009 Elsevier Ltd. All rights reserved.

  inhibition of NF-κB activation might be the mechanism involved in anti-inflammatory effects of these kaurene derivatives. As expected, cytokines IL-6, IL-1α, TNF-α and IFN-γ were downregulated in the presence of compound 28, 55 and 62 after stimulation with LPS. These results indicate that kaurene derivatives might be used for the design of new anti-inflammatory agents.

  制备了一系列的贝壳杉烯衍生物（1 – 63），并评估了其抗炎活性。13种测试化合物能够抑制NO的产生，IC 50为2至10μM。化合物11，12，14和23显示细胞存活力的低百分比，而化合物9，10，17，28，37，48，55，61和62在浓度高达25μM时无细胞毒性。概述了一些结构-活动关系。化合物28，55和62，选择作为代表性的化合物，它们有效地抑制NOS-2蛋白的表达。我们还确定抑制NF-κB活化可能是这些贝壳杉烯衍生物的抗炎作用所涉及的机制。如所预期的，细胞因子IL-6，IL-1α，TNF-α和IFN-γ水平在化合物存在下调28，55和62用LPS刺激后。这些结果表明，kaurene衍生物可用于设计新的抗炎药。
