[Description]

Isolated from the fruit of Murraya koenigii Spreng. this base is closely allied to the two preceding bases as may be seen from the structure. The ultraviolet spectrum, however, differs from that of koenimbidine, having absorption maxima at 230, 240, 300, 340 and 360 mJI. The double bond in the pyrone ring may be reduced with the formation of the dihydro derivative, m.p. 250°C.
[Uses]

Koenimbine is a potential colon cancer medication.
[Definition]

ChEBI: Koenimbine is a member of carbazoles.
