Isolation and Characterization of New Bufotoxins from the Skin of Bufo melanostictus SCHNEIDER.[Reference: WebLink]
The occurrence of new bufotoxins, in which L-histidine, L-3-methylhistidine, or L-1-methylhistidine replaces the arginine residue of hitherto known 'bufotoxin', in the skin of the Formosan toad, Bufo melanostrictus SCHNEIDER, is reported.
METHODS AND RESULTS:
Five novel bufotoxins, bufotalin 3-suberoyl-L-histidine, -3-methylhistidine and -1-methylhistidine esters and 19-Hydroxybufalin 3-suberoyl-L-histidine and -3-methylhistidine esters, were separated by usual chromatographic methods including reversed phase high-performance liquid chromatography, and their structures were elucidated by degradative and synthetic means.
