12 hydroxycorynoline/キケマン属

BACKGROUND Corydalis bungeana Turcz. (CB; family: Corydalis DC.) is an anti-inflammatory medicinal herb used widely in traditional Chinese medicine (TCM) for upper respiratory tract infection, etc., but its anti-inflammatory active molecules are unknown. This study was designed to screen for the

From the herbs of CORYDALIS BUNGEANA, 16 alkaloids were isolated; 3 of them were identical with acetylcorynoline ( 2), corynoline ( 5), protopine ( 9), which had been obtained before from this plant. A further 11 known alkaloids: dihydrosanguinarine ( 1), acetylisocorynoline ( 3), 11-epicorynoline (

High-speed counter-current chromatography (HSCCC) was successfully applied for the preparative separation and purification of alkaloids from Corydalis bungeana Turcz. (Kudiding in Chinese) for the first time. After the measurement of partition coefficient of seven target alkaloids in the nine

The isoquinoline alkaloids isolated from the genus Corydalis possess potent and diverse biological activities. Herein, a concise, divergent, and enantioselective route to access these natural products is disclosed. Key transformations of our approach include a challenging
