We have synthesized an analog of dehydroepiandrosterone (DHEA, 1) containing both a benzophenone (BP) and a biotin (Bt) group (DHEA-BP-Bt, 8). Compound 8 was prepared by functionalization on C-17 of 1. Biocytin was reacted with 4-benzoylbenzoic acid and the product was condensed with 1 containing a diamine-hexane linker. We detected specific protein bands of approximately 55, 80, and 150 kDa by SDS-PAGE analysis of vascular endothelial cell plasma membranes which had been photoirradiated in the presence of 8.
我们合成了一种去氢表雄酮(DHEA,1)类似物,其中包含苯甲酮(BP)和生物素(Bt)基团(DHEA-BP-Bt,8)。化合物 8 通过 1 位 C-17 的官能化制备。生物胞素与 4-苯甲酰苯甲酸反应,产物与含有二胺-己烷连接体的 1 缩合。通过在存在 8 的情况下用光照射血管内皮细胞质膜的 SDS-PAGE 分析,我们检测到大约 55、80 和 150 kDa 的特异性蛋白质带。
