摘要
阿尔茨海默症(AD)是一种神经退行性疾病,其治疗机制主要是抑制胆碱酯酶(ChE)的活性,增加胆碱功能与神经元的传递.天然产物大麻二酚(CBD)具有潜在的神经保护作用.以CBD为原料,通过酯化反应一步合成了一种CBD氨基酸衍生物(CB8),并对其进行体外活性测试.结果表明,CB8 具有良好的抗氧化能力,抑制酪氨酸酶的活性(IC50=(1.02±0.13)μmol/L)和抑制胆碱酯酶的活性(乙酰胆碱酯酶(AChE)IC50=(134.62±0.41)μmol/L,丁酰胆碱酯酶(BuChE)IC50=(1.02±0.13)μmol/L),并且对丁酰胆碱酯酶的抑制活性高于市售药物多奈哌齐4 倍.同时CB8 对PC12 细胞的毒性在(6.25~100 μmol/L)浓度下也与多奈哌齐相当,证明CB8 有治疗阿尔茨海默症的潜力.
Abstract
Alzheimer's disease(AD)is a neurodegenerative disease,and its treatment mechanism mainly involves inhibiting the activity of cholinesterase(ChE),increasing choline function and neuronal transmission.The natural product cannabidiol(CBD)has potential neuroprotective effects.CBD amino acid derivative(CB8)was synthesized in one step by esterification reaction with CBD as raw material,and its activity was tested in vitro.The results show that,CB8 has moderate antioxidant capacity,inhibiting tyrosinase activity(IC50=(1.02±0.13)μmol/L)and inhibiting cholinesterase activity(acetyl cholinesterase(AChE)IC50=(134.62±0.41)μmol/L,butyryl cholinesterase(BuChE)IC50=(1.02±0.13)μmol/L).Moreover,the inhibitory activity against butyryl cholinesterase was 4 times higher than that of the commercially available drug donepezil.At the same time,the toxicity of CB8 to PC12 cells was comparable to donepezil at(6.25~100 μmol/L)concentrations,demonstrating the potential of CB8 in the treatment of Alzheimer's disease.
