Enzyme-Catalyzed Cationic Epoxide Rearrangements in Quinolone Alkaloid Biosynthesis
Epoxides are highly useful synthons and biosynthons for the construction of complex natural products during total synthesis and biosynthesis, respectively. Among enzyme-catalyzed epoxide transformations, a reaction that is notably missing, in regard to the synthetic toolbox, is cationic rearrangement that takes place under strong acid. This is a challenging transformation for enzyme catalysis, ...
متن کاملCryopreservation of Alkaloid-Producing Cell Cultures of Periwinkle (Catharanthus roseus).
A procedure for cryogenic storage of alkaloid producing cell lines of periwinkle, Catharanthus roseus (L.) G. Don., has been developed. The procedure differs from established cryopreservation protocols in several aspects. Specifically, 4-day-old suspension subcultures of three cell lines were precultured in nutrient media supplemented with 1 molar sorbitol for 6 to 20 hours. The cells were then...
متن کاملTranscription factors in alkaloid biosynthesis.
Higher plants produce a large variety of low-molecular weight secondary compounds. Among them, nitrogen-containing alkaloids are the most biologically active and are often used pharmaceutically. Whereas alkaloid chemistry has been intensively investigated, alkaloid biosynthesis, including the relevant biosynthetic enzymes, genes and their regulation, and especially transcription factors, is lar...
متن کاملFifty years of alkaloid biosynthesis in Phytochemistry.
An overview is presented of the studies related to the biosynthesis of alkaloids published in Phytochemistry in the past 50 years.
متن کاملAlkaloid biosynthesis: metabolism and trafficking.
Alkaloids represent a highly diverse group of compounds that are related only by the occurrence of a nitrogen atom in a heterocyclic ring. Plants are estimated to produce approximately 12,000 different alkaloids, which can be organized into groups according to their carbon skeletal structures. Alkaloid biosynthesis in plants involves many catalytic steps, catalyzed by enzymes that belong to a w...
