Comprehensive profiling of acetylcholinesterase inhibitors from fried centipede using activity-oriented online preparation technology
Fried centipede, a popular food in southern China and Vietnam, is well known for its notable health benefits owing to its unique chemical composition. This study focused on acetylcholinesterase (AChE) inhibitor screening, bioactivity evaluation, and the extraction of bioactive compounds derived from fried centipedes. To determine the accuracy of in vitro AChE inhibitor screening, receptor-ligand affinity ultrafiltration and enzymatic reaction kinetics technologies were employed for the rapid screening and structural identification of bioactive compounds and to verify the enzyme inhibition activity and mechanism of the compounds. Moreover, molecular docking and dynamic simulations were utilized to assess the effectiveness of the target, and the integration of experimental and computational approaches facilitated a comprehensive analysis of the active compounds and their activities at four levels. To address the issues of low content and low extraction and separation efficiencies of bioactive compounds derived from centipedes, an activity-oriented complex preparation method (consecutive ultrasonic-assisted centrifugal extraction coupled online with UNIFAC countercurrent chromatography and semi-high-performance liquid chromatography (HPLC) was developed for efficient extraction, online concentration, and complex separation of the identified AChE ligands. As a result, six active compounds, including cytidine, guanine, uracil, hypoxanthine, xanthine, and β-thymidine demonstrated significant binding affinity to the AChE active sites within 3 h. This study provided valuable insights into the active compounds of fried centipedes and their potential anti-Alzheimer's disease properties. These findings contribute to the advancement of animal food preparation methodologies by combining cutting-edge extraction techniques, biological activity screening, and the development of AChE inhibitors from fried centipedes. Our method serves as a valuable reference for exploring and developing functional animal materials from diverse medicinal resources.
