Abstract:

Coptis chinensis is a perennial herb of the Ranunculaceae family. The isoquinoline alkaloid is the main active component of C. chinensis, mainly exists in its rhizomes and has high clinical application potential. The in vitro synthesis of isoquinoline alkaloids is difficult because their structures are complex; hence, plants are still the main source of them. In this study, two-year and four-year rhizomes of C. chinensis were selected to investigate the effect of growth years on the accumulation of isoquinoline alkaloids. Two-year and four-year C. chinensis were selected for metabolomics detec

AbstractThe roots of Stephania tetrandra are used as a traditional Chinese medicine. Isoquinoline alkaloids are considered to be the most important and effective components in this herb, but little is known about the molecular mechanism underlying their biosynthesis. In this context, this study aimed to reveal candidate genes related to isoquinoline alkaloid biosynthesis in S. tetrandra. Determination of tetrandrine and fangchinoline in the roots and leaves of S. tetrandra by HPLC showed that the roots had much higher contents of the two isoquinoline alkaloids than the leaves.

Abstract:

Many isoquinoline alkaloids are biologically active compounds and successfully used as pharmaceuticals. Compounds belonging to the isoquinolines and tetrahydroisoquinolines (TIQs) can be used as anesthetics, antihypertensive drugs, antiviral agents, and vasodilators. In the presented studies, the search for new compounds and synthesis of tetrahydroisoquinoline alkaloid derivatives was undertaken. Several dihydroisoquinolines were synthesized by Bishler–Napieralski reaction from the corresponding amides. Dihydroisoquinolines were reduced with sodium borohydride to obtain racemic tetrahydroisoqu

The fact that the isoquinoline alkaloid stylopine has been identified as a potent AKR1C3 inhibitor has prompted us to screen a library of diverse types of Amaryllidaceae alkaloids, which biogenetically are isoquinoline alkaloids, on a recombinant form of AKR1C3.

Isoquinoline alkaloids-enriched herbal plants have been used as traditional folk medicine for their anti-inflammatory, antimicrobial, and analgesic effects. They induce cell cycle arrest, apoptosis, and autophagy, leading to cell death. While the molecular mechanisms of these effects are not fully understood, it has been suggested that binding to nucleic acids or proteins, enzyme inhibition, and epigenetic modulation by isoquinoline alkaloids may play a role in the effects.

Isoquinoline is a heterocyclic aromatic organic compound. It is a structural isomer of quinoline. Isoquinoline and quinoline are benzopyridines, which are composed of a benzene ring fused to a pyridine ring. In a broader sense, the term isoquinoline is used to make reference to isoquinoline derivatives. 1-Benzylisoquinoline is the structural backbone in naturally occurring alkaloids including papaverine. The isoquinoline ring in these natural compounds derives from the aromatic amino acid tyrosine.

Abstract:

The root bark and the stem bark of Berberis vulgaris L. (16.2 and 6.0 wt.% of total alkaloids) yielded berberine (IIa), magnoflorine (I) and jatrorrhizine (IIc) as major quaternary alkaloids along with small quantities of palmatine (IIb) and alkaloid BV 1. Oxyacanthine and berbamine were separated from the non-quaternary fraction. Isocorydine was the main alkaloid in the leaves. Magnoflorine was also isolated from the stem bark and twigs of Magnolia x soulangeana SOULANGE-BODIN, M. x speciosa REICHENB., and M. kobus DC., from the tubers of Aconitum firmum REICHENB., and from the roots of Clema

Abstract:

A phytochemical survey for alkaloid-containing plants has been conducted in South Sumatra including traditional medicinal plants. During the survey 180 satisfactory herbarium sample were obtained and all of them were tested for alkaloids. The results showed that 33 species gave a positive test for alkaloids, and high alkaloid contents were shown by: Alstonia scholaris, Alstonia angustiloba, Ervatamia coronariaa, Voacanga foetida Bl. K. Schum, Litseaacceden toides K & V, Litsea angualata, Litsea tomentosa, Fibraurea chloroleuca Miers (root), and Uncaria cordata (Lour.) Merr. The aboved surv
