pheochromocytoma PC-12 cell culture. After completion of a total synthesis program, we continued our efforts in reducing complexity by synthetically preparing truncated analogs. Using this approach we were able to not only significantly simplify the structures but also decrease the minimum concentration needed for neuritogenic activity by a factor of 20. This activity was suppressed in the presence of an ERK1/2 inhibitor
最近发现,在嗜铬细胞瘤PC-12细胞培养物中,在不存在神经生长因子(NGF)的情况下,由昆虫病原真菌产生的一组天然产物可诱导神经突生长。在完成总合成计划后,我们继续努力,通过合成制备截短的类似物来降低复杂性。使用这种方法,我们不仅可以显着简化结构,还可以将产生神经活性的最低浓度降低20倍。在ERK1 / 2抑制剂的存在下,该活性被抑制,表明有丝分裂原活化的蛋白激酶被激活(MAPK)途径作为这些吡啶酮生物碱的潜在作用方式。
