摘要
Sinomenine is a clinically available drug for the treatment of rheumatoid arthritis（RA）.In a continuous research aiming at discovery of sinomenine derivates with better bioactivity,a cross-coupling reaction of sinomenine and 1,2-dihydroxybenzene catalyzed by a fungus Coriolus unicolor afforded an unique C-C cross-coupled compound 2,together with（S）-disinomenine and （R）-disinomenine.The structure of 2 was elucidated by MS and NMR spectroscopy.Compound 2 was further assayed for the inhibitory activity on IL-6 overproduction in SW982 cells and exhibited a much more potent activity on IL-6（96%inhibition） compared with those of（S）-disinomenine and sinomenine（17%and 12%inhibition,respectively）.
