Alkaloids can be easily available in our daily food items and act as a consequential element in various pharmaceutical products. Moreover, they have a significant role in the defense mechanism of plants during stress conditions. In this review, we discuss the impact of various stress factors like...
Biosynthesis of the Indole Alkaloids. Cell‐free Systems from Catharanthus roseus Plants Cell-free systems from Catharanthus roseus plants are utilized for various studies relating to the biosynthesis of indole alkaloids. Tryptamine ( 5 ) and secologanin ( 6 ), two fundamental building units, are ...
Proof that morphine is made only by the reticuline-salutaridine route is still lacking and would require a careful comparison of the rate of morphine synthesis with the turnover rates for the various intermediates. More importantly, detailed knowledge of the mechanism of each biochemical step can ...
alkaloids, and other nitrogen-containing compounds (vindoline, camptothecin, steroidal glycoalkaloids, and glucosinolates) in plants. Certain SM, such as carotenoids and anthocyanins, are produced in a wide range of plants, while others, such as vindoline and camptothecin, are ...
Table 1. Summary of the antimicrobial effects of some plant-derived terpenoids, alkaloids, and flavonoids. 2.2. Biosynthesis of Terpenoid Precursors There are two important precursors for terpenoid biosynthesis, dimethylallyl pyrophosphates (DMAPP) and isopentenyl diphosphate (IPP), which can both be ...
Alkaloids Biosynthesis In subject area: Medicine and Dentistry BIA biosynthesis can be categorized into three components: (1) formation of the benzylisoquinoline backbone, (2) rearrangement of the benzylisoquinoline skeleton into various ring-system configurations through carbon–carbon and carbon–oxygen phe...
Cultured roots of Stephania cepharantha, which are rich sources of bisbenzylisoquinoline alkaloids, were fed 14C-labelled tyrosine, tyramine or dopamine. While tyrosine was well incorporated into the bisbenzylisoquinolines, tyramine and dopamine were poorly incorporated. Incorporated tyrosine was shown to...

A review of the literature published between Aug. 1988 and July 1989 concerning the biosynthesis of pyrrolidine, piperidine, phenethylamine and isoquinoline alkaloids, metabolites derived from tryptophan, other metabolites of the shikimate pathway, beta -lactams and various miscellaneous metabolites....
In particular, Ophiorrhiza species (Rubiaceae) are important resources for the production of various alkaloids, including camptothecin. This chapter describes the production of camptothecin-related alkaloids and the elucidation of the mechanisms of camptothecin biosynthesis using plant cell and tissue ...
