Bis-piperidine alkaloids from the peels of Areca catechu
Journal of Asian Natural Products Research(2024)
Abstract
Four new alkaloids, arecatines A–D (1–4), were isolated from the peels of Areca catechu. Compound 1 is an unusual piperidine-pyridine hybrid alkaloid, whereas compounds 2–4 feature bis-piperidine alkaloids. Their structures were elucidated by UV, IR, HRESIMS, and NMR spectra analysis. The molecular docking analysis indicated that compound 3 exhibited the best binding affinity with the GABAA receptor, indicating its potential anti-epilepsy activity.
