Saudin is a diterpenoid first isolated from the African flowering plant Cluytia richardiana.^[1]

Saudin has shown a hypoglycemic effect in an rodent model experiment.^[2]

Because of the unusual chemical structure and its potential biological activity, there has been research aimed at its total synthesis.^[3]^[4]^[5]^[6]^[7]
