Bufoviridine

Bufoviridine, also known as bufotenine O-sulfate, dihydrobufothionine, or 5-sulfooxy-N,''N-dimethyltryptamine, is a naturally occurring tryptamine found in Bufo species such as Bufo viridis and Bufo calamita. It is the O''-sulfate ester of bufotenin. The compound shows very weak serotonergic activity. Bufoviridine is not known to have been evaluated in humans, but is suggested to be inactive based on animal studies. The 4-O-acetate, 4-O-phosphate, and 4-O-benzoate esters of psilocin are all active, but the 4-O-sulfate ester is inactive, suggesting that bufoviridine may be inactive as well. It was first described in the 1950s.
