Synthesis of some new acylhydrazone compounds containing the 1,2,4-triazole structure and their neuritogenic activities in Neuro-2a cells†
Abstract
In the present study, a novel series of acylhydrazone compounds (A0–A10) with the structure of 1,2,4-triazole have been designed and synthesized. In addition, all the synthesized compounds have been evaluated for neuritogenic activity in mouse neuroblastoma (Neuro-2a) cells. Notably, we found that one of these 11 acylhydrazone compounds, compound A5 (2-(4-amino-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-ylthio)-N′-(2-hydroxybenzylidene)-acetohydrazide) displays excellent neuritogenic activity. Moreover, our present study revealed that compound A5 had the ability to induce neurite outgrowth through the PI3K/Akt and MEK-ERK signaling pathway in Neuro-2a cells. These findings suggest that compound A5 might exert neuritogenic effects and thus may be useful for the treatment of neural repair and regeneration.
