Gx-50 is a bioactive compound for the treatment of Alzheimer’s disease (AD) found in Sichuan pepper (Zanthoxylum bungeanum). In order to find a stronger anti-AD lead compound, 20 gx-50 (1–20) analogs have been designed and synthesized, and their molecular structures were determined based on nuclear magnetic resonance (NMR) and mass spectrometry (MS) analysis, as well as comparison with literature data. Compounds 1–20 were evaluated for their anti-AD potential by using DPPH radical scavenging assay for considering their anti-oxidant activity, thioflavin T (ThT) fluorescence assay for considering the inhibitory or disaggregate potency of Aβ, and transgenic Drosophila model assay for evaluating their rescue effect on memory loss. Finally, compound 13 was determined as a promising anti-AD candidate.
Gx-50是一种用于治疗阿尔茨海默病(AD)的生物活性化合物,发现于花椒(Zanthoxylum bungeanum)中。为了寻找更强的抗AD活性化合物,设计和合成了20个gx-50(1-20)类似物,并通过核磁共振(NMR)和质谱分析(MS)以及与文献数据的比较确定了它们的分子结构。通过使用DPPH自由基清除实验评估化合物1-20的抗AD潜力,考虑其抗氧化活性;使用ThT荧光实验考虑其对Aβ的抑制或解聚作用;使用转基因果蝇模型实验评估其对记忆丧失的救助效果。最终,确定化合物13为有希望的抗AD候选化合物。
