Chemical compound
Stemmadenine is a terpene indole alkaloid. Stemmadenine is believed to be formed from preakuammicine by a carbon-carbon bond cleavage. Cleavage of a second carbon-carbon bond is thought to form dehydrosecodine.[1] The enzymes forming stemmadenine and using it as a substrate remain unknown to date. It is thought to be intermediate compound in many different biosynthetic pathways[2][3][4] such as in Aspidosperma species.[5] Many alkaloids are proposed to be produced through intermediate stemmadenine. Some of them are:
Catharanthine and Tabersonine in Catharanthus roseus[4][2]
Subincanadines D-F in Aspidosperma subincanum[3]
It is also present as product in plant like in Tabernaemontana dichotoma seeds.[6]
