Studies on indole alkaloids [PDF]

, 1936
Among different types of alkaloids the structure of those derived from indole is least known. The constitution of only very few members of this group is fixed, and in most cases it remains obscure.#1. On the Alkaloids of Calycanthus floridus L.

Environmental stress induced biosynthesis of plant secondary metabolites- transcriptional regulation as a key

Crop Design
Secondary metabolites represnt are diverse array of plant-synthesized compounds that, while not essential for growth and development, play crucial roles in plant defense against biotic and abiotic stresses, attracting pollinators and seed dispersers, and

Indole Alkaloids from Chaetomium globosum

, 2015
Two new indole alkaloids chaetocochin J (1) and chaetoglobinol A (8), along with chetomin (2), chetoseminudin A (3), cochliodinol (9), and semicochliodinol (10), were isolated from the rice culture of the fungus Chaetomium globosum. Their structures were

Identification and Functional Characterization of a Geraniol Synthase UrGES from Uncaria rhynchophylla

Plants
Uncaria rhynchophylla, a medicinal plant extensively used in traditional Chinese medicine, is an important plant source of terpenoid indole alkaloids (TIAs), but the mechanism of TIA biosynthesis at molecular level remains unclear. Geraniol synthase (GES)

Jasmonic Acid Effect on the Fatty Acid and Terpenoid Indole Alkaloid Accumulation in Cell Suspension Cultures of Catharanthus roseus

Molecules, 2014
The stress response after jasmonic acid (JA) treatment was studied in cell suspension cultures of Catharanthus roseus. The effect of JA on the primary and secondary metabolism was based on changes in profiles of fatty acids (FA) and terpenoid indole ...
