为了寻找能够促进成年小鼠海马神经元形成的化学物质,进行了体内筛选。1000个小分子中的8个被测试增强了齿状回亚颗粒区神经元的形成。其中有一种氨基丙基咔唑,命名为P7C3,具有良好的药理作用。体内研究证明P7C3通过保护新生神经元免于凋亡发挥其神经原性活性。缺失神经元PAS结构域蛋白3 (NPAS3)编码基因的小鼠海马神经发生缺失,齿状回出现畸形和电生理功能障碍。长期给予npas3-/-小鼠P7C3通过使新生海马神经元凋亡水平正常化来纠正这些缺陷。老年大鼠长期服用P7C3还可以增强齿状回的神经发生,阻碍神经元死亡,并保持认知能力,这是衰老末期的功能。
An in vivo screen was performed in search of chemicals capable of enhancing neuron formation in the hippocampus of adult mice. Eight of 1,000 small molecules tested enhanced neuron formation in the subgranular zone of the dentate gyrus. Among these was an aminopropyl carbazole, designated P7C3, endowed with favorable pharmacological properties. In vivo studies gave evidence that P7C3 exerts its pro-neurogenic activity by protecting newborn neurons from apoptosis. Mice missing the gene encoding neuronal PAS domain protein 3 (NPAS3) are devoid of hippocampal neurogenesis and display malformation and electrophysiological dysfunction of the dentate gyrus. Prolonged administration of P7C3 to npas3-/- mice corrected these deficits by normalizing levels of apoptosis of newborn hippocampal neurons. Prolonged administration of P7C3 to aged rats also enhanced neurogenesis in the dentate gyrus, impeded neuron death, and preserved cognitive capacity as a function of terminal aging.
