Biotransformation of tryptamine and secologanin into plant terpenoid indole alkaloids by transgenic yeast

Applied Microbiology and Biotechnology, 2001
A transgenic Saccharomyces cerevisiae was constructed containing the cDNAs coding for strictosidine synthase (STR) and strictosidine beta-glucosidase (SGD) from the medicinal plant Catharanthus roseus. Both enzymes are involved in the biosynthesis of terpenoid indole alkaloids. The yeast culture was found to express high levels of both enzymes.

Loganin and secologanin derived tryptamine–iridoid alkaloids from Palicourea crocea and Palicourea padifolia (Rubiaceae)

Phytochemistry, 2015
During comparative analysis on Palicourea species from Costa Rica, two unusual loganin derived tryptamine-iridoid alkaloids were isolated from an accession of Palicourea crocea. Besides the already known brachycerine (2), palicroceaine (1) features a novel hexacyclic backbone.

Alkaloid formation in cell suspension cultures of Tabernaemontana elegans after feeding of tryptamine and loganin or secologanin

Plant Cell, Tissue and Organ Culture, 2002
A cell suspension culture of Tabernaemontana elegans lost its ability to produce alkaloids after a prolonged period of subculture. To determine whether it was still capable of performing the later steps of the alkaloid biosynthetic pathway, the culture was fed with tryptamine and loganin.

First synthesis of hunterioside, a novel disaccharide carrying monoterpenoid indole alkaloid, by assembly of three components, tryptamine, secologanin, and a newly-developed glucosyl donor

Tetrahedron Letters, 1999
Abstract The novel structure of hunterioside, the first example of monoterpenoid indole alkaloids carrying a disaccharide, was confirmed by chemical synthesis starting from tryptamine, secologanin, and a newly-developed gulucosyl donor, which selectively gives α-gluco type glycosidic linkage in the reaction with a secologanin derivative.
