Cytotoxic bisbenzylisoquinoline alkaloids from the roots of Cyclea racemosa.[Pubmed: 20593839]
Six new bisbenzylisoquinoline alkaloids, racemosidines A-C (1-3) and racemosinines A-C (4-6), and four known compounds were isolated from the roots of Cyclea racemosa. Compound 1 is the first bisbenzylisoquinoline alkaloid reported that has diphenyl ether bridges at C-11/C-7' and C-8/C-12' and a benzyl-phenyl ether bridge at C-7/C-11'. Structures and absolute configurations of 1-6 were established by interpretation of spectroscopic data and confirmed by X-ray crystallographic analysis of representative compounds. Compounds 1-3 exhibited significant cytotoxicity against HCT-8 and BEL-7402 tumor cells, and compound 1 was also cytotoxic against A2780 tumor cells.
