This work is part of a large program, which seeks to discover new antitumor isobenfuranones designed from anacardic acids. The synthetic strategy for the construction of the title compounds takes into consideration the use of inexpensive anacardic acids (2), the major natural cashew (Anacardium occidentale) nut-shell phenolic lipid, and features one-pot construction of fused-ring aromatic γ-lactones
这项工作是一个大型计划的一部分,该计划旨在发现由漆树酸制得的新抗肿瘤异苯并呋喃酮。构建标题化合物的合成策略考虑到了使用廉价的伞花酸(2),主要的天然腰果(Anacardium occidentale)坚果壳酚类脂,并具有一锅式稠合环芳族γ-结构的特点。内酯,邻苯二甲酸酯。通过MTT分析在不同的人类癌细胞系(HL-60白血病,SF295胶质母细胞瘤和MDA-MB435黑色素瘤)中进行的细胞毒性筛选显示,无环前体(6)和异苯并呋喃酮(1a和1b)是活性化合物。有趣的是1a对HL-60细胞具有显着的抗增殖作用,对SF295和MDA-MB435细胞系具有中等活性。对涉及细胞毒性活性的机制的分析表明,活性化合物导致DNA损伤,引发细胞凋亡或坏死诱导。
