In clinical. acetylcholinesterase inhibitors reduce the breakdown of synaptic acetylcholine, have been modestly effective in improving the cognitive deficits of Alzheimer's disease.The goal of this work is to determine enzyme kinetics and mechanisms of acetylcholinesterase and butyrlcholinesterase inhibition by five cardiovascular drugs, lovastatin, simvastatin, amlodipine besylate, nifedipine, and hydralazine hydrochloride, and two benzodiazepines, diazepam and chlordiazepoxide hydrochloride. All drugs in this study are reversible mixed-type inhibitors of acetylcholinesterase and butyrylcholinesterase. The pKi values for acetylcholinesterase and butyrylcholinesterase inhibition by the cardiovascular drugs are linearly correlated with the molecular weights of the drugs with the slopes of 0.005 and 0.0021, respectively. Therefore, van der Waals' interactions between acetylcholinesterase and the cardiovascular drugs are stronger than those between butyrylcholinesterase and the drugs. This is probably due to a smaller active site gorge and a more significant peripheral anionic substrate binding site of acetylcholinesterase than those of butyrylcholinesterase.

本研究之目的系决定乙醯胆碱酯酵素和丁醯胆碱酯酵素被五种心脏血管药物lovastatin， simvastatin， amlodipine besylate， nifedipine、hydralazine hydrochloride和两种benzodiazepines：diazepam和Chlordiazepoxide hydrochloride的抑制作用之动力学及机转，这些药物都是乙醯胆碱酯酵素和丁醯胆碱酯酵素的可逆性、混合型之抑制剂，实验结果显示，五种心血管药物对於乙醯胆碱酯酵素及丁醯胆碱酯酵素抑制之pKi值和药物之分子量呈直线之关系，斜率分别为0.005及0.0021因此丁醯胆碱酯酵素，与心血管药物间之凡德瓦作用（van der Waals' ）比乙醯胆碱酯酵素与心血管药物间者弱，这可能原因是丁醯胆碱酯酵素之活性区域比乙醯胆碱酯酵素之活性区域更宽广，但丁醯胆碱酯酵素之周边阴离子区域不及乙醯胆碱酯酵素之周边阴离子区域者明显重要，由於五种心血管药物对於乙醯胆碱酯酵素和丁醯胆碱酯酵素抑制之pKi值存在著线性关系表示此种抑制作用系经过共同之反应机理。
