  Withaferin A-related steroids from Withania aristata exhibit potent antiproliferative activity by inducing apoptosis in human tumor cells

  摘要：

  Six new withanolides (1-6) along with eleven known ones (7-17) were isolated from the leaves of Withania aristata. Their structures were elucidated on the basis of spectroscopic analysis, including 1D and 2D NMR techniques. Semisynthesis of the minority metabolites 7 and 15 from compounds 6 and 9, respectively, as starting material, was performed. The isolated compounds as well as three derivatives (7a, 9a and 9b) of withaferin A were evaluated for cytotoxicity against HeLa (carcinoma of the cervix), A549 (lung carcinoma) and MCF-7 (breast adenocarcinoma) human cancer cell lines, and against normal Vero cells (African green monkey kidney). Five compounds from this series (8, 9a, 9b, 11 and 13) exhibited potent antiproliferative effects on the tumor cells, even higher than the well known anticancer agent, withaferin A (9). Phosphatidylserine externalization, chromatin condensation, and caspase-3 activation clearly indicated apoptosis as a mechanism of action. The structure-activity relationship revealed valuable information on the pharmacophore for withanolide-type compounds. (C) 2012 Elsevier Masson SAS. All rights reserved.

  基于结构的设计，合成和生物素作为潜在的凋亡诱导剂的Aferalogues的生物学评估。

  摘要：

  凋亡诱导剂是发现和开发抗癌剂的一种有吸引力的方法。在此，我们通过的分子微调睡茄素的63种化合物（基于A-文库发展报告2 - 64），它们中的53报道首次。他们对HeLa，A-549和MCF-7人肿瘤细胞系的抗增殖评估确定了十五种类似物，它们的活性（IC 50值范围为0.3–4.8μM）比铅（IC 50）高。值处于滞后或对数生长期的数值（1.3-10.1μM）。SAR分析表明，酰化作用增强了细胞毒性，表明疏水性部分可能通过增加亲和力和/或细胞膜通透性而有助于细胞活性。进一步调查清楚地表明，化合物3，11，12，和18诱导染色质缩合，磷脂酰丝氨酸外翻，并且在HeLa细胞胱天蛋白酶-3激活的细胞凋亡效果证明。在G2 / M中诱导细胞凋亡并伴随细胞丢失的有效能力凸显了27-苄基类似物（18）作为凋亡诱导药物候选物的潜力。

  investigation clearly indicated that compounds 3, 11, 12, and 18 induce apoptosis evidenced by chromatin condensation, phosphatidylserine externalization, and caspase-3 activation effects on HeLa cells. The potent capacity to induce apoptosis with concomitant cell loss in G2/M highlights the potential of 27-benzyl analogue (18) as an apoptotic inducer drug candidate.
