Strictosidine
Strictosidine is formed by the Pictet–Spengler reaction condensation of tryptamine with secologanin by the enzyme strictosidine synthase. Thousands of strictosidine derivatives are sometimes referred to by the broad phrase of monoterpene indole alkaloids.[1][2] Strictosidine is the base molecule for numerous pharmaceutically valuable metabolites including quinine, camptothecin, ajmalicine, serpentine, vinblastine and vincristine.

Distribution
Strictosidine is found in the following plant families.
Recent efforts in metabolic engineering have permitted the synthesis of strictosidine by yeast (Saccharomyces cerevisiae).[5] This was accomplished by adding 21 genes and 3 gene deletions.
