What is Speciociliatine?
Speciociliatine is a monoterpenoid indole alkaloid and a diastereomer of mitragynine, sharing the molecular formula C23H30N2O4, that occurs naturally as a minor alkaloid in the leaves of Mitragyna speciosa.
Where does Speciociliatine occur naturally?
Speciociliatine occurs in the leaves of Mitragyna speciosa (kratom), typically as one of the minor alkaloids within the leaf alkaloid fraction.
How is Speciociliatine related to mitragynine?
Speciociliatine and mitragynine are both monoterpenoid indole alkaloids from Mitragyna speciosa that share the same indole scaffold; Speciociliatine has the molecular formula C23H30N2O4 and mitragynine has the molecular formula C23H30N2O4.
Structure and chemistry
Speciociliatine shares the indole and quinolizidine framework of mitragynine and differs from it in stereochemistry at the C-3 position, making it a corynanthe-type diastereomer.
Because it is a stereoisomer of mitragynine, it has the identical molecular formula and closely related structural features, and it is distinguished analytically by chromatographic separation.
