towards several cancer cell lines without significant tumor-promoting and proinflammatory activities. To determine the effects of the phenolic group on the biological activities of 1, we synthesized new derivatives (2, 3) that lack the phenolic hydroxyl group and/or the aromatic ring. Compound 2, like 1, showed potent anti-proliferative activity against several cancer cell lines, but little with respect
Aplysiatoxin (ATX) 是一种蛋白激酶 C (PKC) 激活剂,具有有效的促肿瘤活性。相比之下,ATX 的简化类似物 10-methyl-aplog-1 (1) 对几种癌细胞系具有抗增殖作用,但没有显着的促肿瘤和促炎活性。为了确定酚基对 1 生物活性的影响,我们合成了缺乏酚羟基和/或芳环的新衍生物 (2, 3)。与 1 一样,化合物 2 对几种癌细胞系显示出有效的抗增殖活性,但在促肿瘤和促炎活性方面却很少。相比之下,3 表现出较弱的生长抑制活性,并促进炎症和肿瘤发生。3 对 PKCδ 的结合亲和力,PKCδ 参与生长抑制和细胞凋亡,比 1 和 2 低几倍,可能是由于其侧链与 PKCδ-C1B 结构域中的 Met-239 或 Pro-241 之间不存在氢键和 CH/π 相互作用。这些结果表明,芳香环和酚羟基都可以抑制 1 的促炎和促肿瘤活性,因此,至少 1 侧链中的芳香环对于开
