Quaternary isoquinoline alkaloids from Stephania cepharantha.
From the quaternary alkaloidal fraction of the dried tubers of Stephania cepharantha, two new isoquinoline alkaloids, stecepharine and tetradehydroreticuline have been isolated along with the known compounds, magnoflorine, menisperine, steponine, cyclanoline, oblongine, cis-N-methylcapaurine and 2'-N-methylisotetrandrine. cis-N-Methylcapaurine (=9-O-methylstecepharine) was isolated as a natural...
متن کاملNew cytotoxic tetrahydroprotoberberine-aporphine dimeric and aporphine alkaloids from Corydalis turtschaninovii.
Two new tetrahydroprotoberberine-aporphine dimeric alkaloids, corydaturtschines A (1) and B (2), and a new aporphine derivative, ethyl glausuccinate (3), together with 13 known protoberberine (4-16) and nine known aporphine alkaloids (17-25), were isolated from the tubers of Corydalis turtschaninovii. The structures of these new compounds were determined through spectral analyses, including ext...
متن کاملAntiviral and antimicrobial profiles of selected isoquinoline alkaloids from Fumaria and Corydalis species.
In the current study, 33 isoquinoline alkaloids belonging to protopine-, benzylisoquinoline-, benzophenanthridine-, spirobenzylisoquinoline-, phthalideisoquinoline-, aporphine-, protoberberine-, cularine-, and isoquinolone-types as well as 7 derivatives of them obtained from some Fumaria and Corydalis species growing in Turkey have been evaluated for their in vitro antiviral and antimicrobial a...
متن کاملIsoquinoline alkaloids isolated from Corydalis yanhusuo and their binding affinities at the dopamine D1 receptor.
Bioactivity-guided fractionation of Corydalis yanhusuo has resulted in the isolation of eight known isoquinoline alkaloids - tetrahydropalmatine, isocorypalmine, stylopine, corydaline, columbamine, coptisin, 13-methylpalmatine, and dehydrocorybulbine. The tertiary alkaloids were further analyzed by chiral HPLC to determine the ratios of d-and l-isomers. The isolated compounds were screened for ...
متن کاملIsoquinoline alkaloids such as coptisine, berberine and palmatine isolated from the rhizome of Coptis japonica
palmatine isolated from the rhizome of Coptis japonica MAKINO have been demonstrated to exert wide ranges of biological and pharmacological activities. In particular, the major medically important isoquinoline alkaloid, berberine, has been extensively studied and recently reported to display beneficial effects in the treatment of diabetes, obesity and hyperlipidemia, while both coptisine and pa...
