产品描述

Talatisamine is a diterpene alkaloid originally isolated from A. talassicum and has diverse biological activities.1,2,3,4,5 It blocks delayed rectifier potassium (IK) current in rat hippocampal neurons (IC50 = 146 μM).3 Talatisamine reduces increases in IK current and cytotoxicity in primary rat cortical neurons induced by amyloid-β (1-40) .4 It inhibits barium chloride-induced contractions in isolated rat intenstines (EC50 = 200 μM).2 Talatisamine exhibits feeding deterrent activity against red flour beetle (T. castaneum) adults (EC50 = 342.8 ppm).5
