The ability of natural and synthetic compounds to stimulate transforming growth factor alpha (TFGα) release, to increase neural progenitor cell proliferation, and to stimulate neurogenesis was evaluated. All compounds that facilitated TGFα release promoted neural progenitor cell proliferation. The presence of two acyloxy moieties on the tigliane skeleton led to higher levels of activity, which decreased
制备了带有低亲脂性酯链的佛波醇 12,13-二酯的小型文库,作为成人大脑中潜在的神经源性药物。它们还用于大戟胶乳的靶向 UHPLC-HRMS 筛选. 分离出两种新的 12-deoxy-16-hydroxyphorbol 13,16-二酯,并使用二维 NMR 光谱和 NOE 实验推断了它们的结构。评估了天然和合成化合物刺激转化生长因子 α (TFGα) 释放、增加神经祖细胞增殖和刺激神经发生的能力。所有促进 TGFα 释放的化合物都促进了神经祖细胞的增殖。tigliane 骨架上两个酰氧基部分的存在导致更高水平的活性,当游离羟基位于 C-12 时,活性水平降低。值得注意的是,带有异丁酰氧基的化合物在 TGFα 测定和体外诱导神经祖细胞增殖方面最有效,也导致体内神经发生增强当对小鼠鼻内给药时。
