Food Frontiers, Volume 7, Issue 3, May 2026.Natural compounds regulate gut microbiota by improving microbial balance and increasing probiotics, which boost short‐chain fatty acid production to alleviate insulin resistance and inflammation. Additionally, they stimulate appetite‐suppressing hormones through bile acid signaling, while inhibiting pathogenic bacteria to repair intestinal barrier ...

Chemical Studies of Indole Alkaloids
YAKUGAKU ZASSHI, 1995 Up to now, more than two thousands indole alkaloids having structural variety have been found from the three families of Gentianales: Loganiaceae, Apocynaceae, and Rubiaceae plants. These compounds generally possess characteristic biological activities and many of them are utilized for the medicinal purpose and for the lead-compounds to develop new ...

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.ABSTRACT Ergot alkaloids (EAs), toxic secondary metabolites produced by Claviceps purpurea, pose food and feed safety concerns for cereal grains, particularly rye and wheat. While EAs are most frequently associated with rye, their occurrence in other cereals has been increasingly reported across diverse regions.

Plant, Cell &Environment, Volume 49, Issue 5, Page 2394-2412, May 2026.ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Total synthesis of asperdinones B, C, D, E and terezine D
Beilstein Journal of Organic ChemistryThe total synthesis of new members of prenylated indole alkaloids exhibiting α-glucosidase activity is described. Asperdinones B, C, D, and E are characterized by the presence of a (3R)-3-indolylmethylbenzodiazepine-2,5-dione unit at C-3 of C4–C7 ...

Preparation of indole alkaloids via 1,4-dihydropyridine stage or cyano-masked iminium intermediates [PDF]
, 2004 Methods to synthesise substituted pyridine derivatives utilising 1,4-dihydropyridines were studied. Addition of nucleophiles to N-alkyl pyridinium salts and application of the products to alkaloid synthesis were investigated.

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Nile tilapia (Oreochromis niloticus), a key species in global freshwater aquaculture and a major contributor to Bangladesh's fish production, is increasingly affected by bacterial infections that compromise farm productivity. This study investigated natural co‐infection of bacterial pathogens in diseased tilapia and assessed the effectiveness ...
