Cardamonin Commands the Colonic Metabolite Columbianetin Acetate to Compete Against LPS in Binding HMGB1 in the Kidney, Preventing Lipopolysaccharide‐Induced Renal Tubular Pyroptosis

Food Frontiers, EarlyView.
Cardamonin upregulate sd the intestinal metabolite columbianetin acetate, which competitively bound HMGB1 to prevent LPS‐induced renal tubular cell pyroptosis (the figure is created with BioRender). ABSTRACT Sepsis‐associated acute kidney injury (SA‐AKI) results in high mortality due to the lack of effective interventions. The current study reports the

Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

Food Frontiers, EarlyView.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Effect of Molecular Perturbation on Polymorphism: The Case of 8-Halotheophyllines (8-Cl-Tph and 8-Br-Tph)

Crystals
The common alkaloid theophylline (Tph) is known to exist in five polymorphic forms. The structures of its 8-halo analogues were previously unreported. Here, we report three polymorphs for 8-chlorotheophylline (8-Cl-Tph) and an additional distinct one for

Asymmetric total synthesis of alkaloid natural products without external chiral sources [PDF]

, 2018
The chirality of a starting material having a chiral sp3-carbon can be preserved under some circumstances in the reaction product even though the reaction proceeds at the chiral carbon as a reaction center through reactive intermediates.

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

Food Frontiers, EarlyView.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.
