Abstract:

Cholinesterase inhibitors targeting acetylcholinesterase and butyryl cholinesterase were screened from alcohol extracts of evodia rutaecarni. The pharmacokinetic process of small molecule compounds in evodia evodia alcohol extract was studied by ultra fast liquid chromatography-mass spectrometry(UFLC-MS). At the same time, UFLC-MS analysis method included specificity, linearity, precision, accuracy, stability, the matrix effect and recovery projects such as a comprehensive inspection. The results show that the method is stable and reliable, and 10 alkaloids compounds in alcohol extract can be absorbed quickly, gastrointestinal tract and the majority of compound blood drug concentration peak at about 1—2 h. Flexible molecular docking and structurally activity analysis of 10 alkaloid compounds with acetylcholinesterase and butylcholinesterase were conducted. It was found that the four compounds with the highest activity were indole-type alkaloids, namely evodiamine, rutaecarpine, dehydroevodiamine and wuchuyuamide Ⅰ, respectively. Their docking scores with acetylcholinesterase were all below -46.02 kJ/mol. The docking scores with butylcholinesterase were all below -41.84 kJ/mol. Evodiamine, rutaecarpine, dehydroevodiamine and wuchuyuamide may be precursor compounds of cholinesterase inhibitors targeting acetylcholinesterase and butyryl cholinesterase.
