Characterization of regio- and stereo-selective sulfation of bufadienolides: exploring the mechanism and providing insight into the structure–sulfation relationship by experimentation and molecular docking analysis
bufadienolides (including bufalin, resibufogenin, cinobufagin, bufotalin, telocinobufagin and deacetylcinobufagin) in amphibian skin secretion and to provide insight into the structure–sulfation relationship by experimentation and molecular docking analysis with series of bufadienolides and derivatives. For all the six representative bufadienolides, one corresponding monosulfate was detected in the incubation
