Synthesis of long-chain fatty acid derivatives as a novel anti-Alzheimer’s agent

In order to develop new drugs for Alzheimer’s disease, we prepared 17 fatty acid derivatives with different chain lengths and different numbers and positions of double bonds by using Wittig reaction and stereospecific hydrogenation of triple bonds as key reactions. Among them, (4Z,15Z)-octadecadienoic acid (10) and (23Z,34Z)-heptatriacontadienoic acid (16) showed the most potent neurite outgrowth activities on Aβ(25–35)-treated rat cortical...
