Strictosidine
Strictosidine is a natural chemical compound and is classified as a glucoalkaloid and a vinca alkaloid. It is formed by the Pictet–Spengler condensation reaction of tryptamine with secologanin, catalyzed by the enzyme strictosidine synthase. Thousands of strictosidine derivatives are sometimes referred to by the broad phrase of monoterpene indole alkaloids. Strictosidine is an intermediate in the biosynthesis of numerous pharmaceutically valuable metabolites including quinine, camptothecin, ajmalicine, serpentine, vinblastine, vincristine and mitragynine.
Biosynthetic pathways help to define the subgroups of strictosidine derivatives.
Distribution
Strictosidine is found in the following plant families:Here especially in Rhazya stricta and Catharanthus roseus.
Recent efforts in metabolic engineering have permitted the synthesis of strictosidine by yeast. This was accomplished by adding 21 genes and 3 gene deletions.
