In a continuing study on discovery of more potent derivatives of sinomenine (1), a clinically available alkaloid for rheumatoid arthritis (RA) treatment, oxidation of sinomenine provided two unique stereoisomers, disinomenines 2 and 3. The structure of 3 was determined by MS' NMR, and X-ray analysis. The formation of 2 and 3 via oxidation of sinomenine by potassium permanganate (KMnO4) exhibited a pH-dependent stereoselectivity. The bioassay results using human synovial sarcoma cells (SW982) showed that 2 inhibited, while 3 stimulated, IL-6 production.

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).
