Oxidative cyclization of bis-naphthyl ethers allows concise total syntheses of palmarumycin CP, and deoxypreussomerin A in 8-9 steps and 15-35% overall yield from 5-hydroxy-8-methoxy-1 -tetralone. A small library of palmarumycin analogs was created. Biological evaluation of these naphthoquinone spiroketals against MCF-7 and MDA-MB-23 1 human breast cancer cells revealed several low-micromolar growth inhibitors. A number of the analogs inhibit the thioredoxin -thioredoxin reductase system.
通过双萘醚的氧化环化反应,可以从 5-hydroxy-8-methoxy-1 -tetralone(5-羟基-8-甲氧基-1-四氢萘酮)出发,以 8-9 个步骤和 15-35% 的总收率,简便地全合成出棕榈霉素 CP 和脱氧普鲁索梅林 A。我们建立了一个小型的香豆素类似物库。对这些萘醌螺环酮类化合物针对 MCF-7 和 MDA-MB-23 1 人类乳腺癌细胞进行的生物学评估发现了几种低微摩生长抑制剂。其中一些类似物可抑制硫氧还蛋白-硫氧还蛋白还原酶系统。
