Photo-activated DNA binding and antimicrobial activities of alkaloids from Glycosmis pentaphylla.


In our screening for photosensitizers from natural resources, four alkaloids were isolated from Glycosmis pentaphylla by various chromatography techniques. Their structures were identified as glycoborinine (1), glybomine B (2), carbalexin A (3) and N-p-coumaroyltyramine (4) by spectral analysis. Their photoactivated antimicrobial activities were evaluated… (More)
