Aphorpines and benzylisoquinoline alkaloids from bark of Cryptocarya crassinervia
نویسنده
چکیده
Two aphorpine alkaloids, (+)-lirinine 1 and (+)-lirioferine 2 and two bezylisoquinoline alkaloids (+)reticuline 3 and (-)-N-Methylisococlaurine 4 were isolated from bark of Cryptocarya crassinervia. The structures were elucidated by spectral analysis, including 1D-NMR (H, C, DEPT), 2D-NMR (COSY, HMQC, HMBC), UV, IR, and MS and comparison with the published data.

متن کاملAntiplasmodial alkaloids from the bark of Cryptocarya nigra (Lauraceae).
A dichloromethane extract of the stem bark of Cryptocarya nigra showed strong in vitro inhibition of Plasmodium falciparum growth, with an IC50 value of 2.82 μg/mL. The phytochemical study of this extract has led to the isolation and characterization of four known alkaloids: (+)-N-methylisococlaurine (1), atherosperminine (2), 2-hydroxyathersperminine (3), and noratherosperminine (4). Structura...
متن کاملBIAdb: A curated database of benzylisoquinoline alkaloids
BACKGROUND Benzylisoquinoline is the structural backbone of many alkaloids with a wide variety of structures including papaverine, noscapine, codeine, morphine, apomorphine, berberine, protopine and tubocurarine. Many benzylisoquinoline alkaloids have been reported to show therapeutic properties and to act as novel medicines. Thus it is important to collect and compile benzylisoquinoline alkalo...

A new flavanone, 7-hydroxy-5,6-dimethoxyflavanone (1), together with three other flavonoids, didymocarpin (2), 2',4'-dihydroxy-5',6'-dimethoxychalcone (3), and isodidymocarpin (4), had been isolated from the methanol extract of the tree bark of Cryptocarya costata. The structures of these compounds were determined based on spectral evidence, including UV, IR, 1-D and 2-D NMR, and mass spectra. ...
