#metabolite

• Abelia genus — A genus of ornamental flowering shrubs in the family Caprifoliaceae, native to East Asia and Mexico. In pharmaceutical botany, toxicology, and neuropsychiatry, extracts from Abelia species are studied for their content of biologically active secondary metabolites (iridoid glucosides, polyphenols). These compounds display antioxidant and neuroprotective therapeutic potential, being clinically investigated in experimental models to reduce oxidative stress in neurodegenerative diseases or alleviate neurosomatic anxiety symptoms.
• Abeliophyllum genus — A monotypic botanical genus in the family Oleaceae, represented exclusively by the species Abeliophyllum distichum (Korean white forsythia). In pharmaceutical botany, phyto-neurosciences, and toxicology, extracts from the aerial organs of this plant are intensively studied for their high concentration of phenylethanoid glycosides, flavonoids, and verbascoside compounds. These secondary metabolites display potent antioxidant, anti-inflammatory, and neuroprotective properties, being investigated in vitro and in vivo for their ability to mitigate neuroinflammation, inhibit acetylcholinesterase, and protect neuronal cells against oxidative stress-induced degradation in degenerative cognitive pathologies.
• Alkaloid — A nitrogenous organic substance, typically possessing a basic (alkaline) character and a complex heterocyclic structure, primarily biosynthesized by plants, but also by certain fungi or animals. Alkaloids exhibit intense pharmacodynamic action on the central nervous system and the human body, functioning, depending on the dosage, as essential medicines, stimulants, or highly violent poisons (for example: morphine, caffeine, nicotine, atropine, quinine).
• Anabolite — A chemical substance, molecule, or organic compound directly resulting from a process of anabolism or used as a precursor in cellular biosynthesis reactions. It represents the structural building block used by the cell for energy storage or macromolecule formation, being the opposite of a catabolite.
• Antimetabolite — A natural or synthetic chemical substance whose molecular structure closely resembles that of an essential metabolite in the body, capable of blocking, competing with, or inhibiting its normal utilization in cellular processes; in a clinical sense, it is used in chemotherapy (such as methotrexate or fluorouracil) to sabotage DNA synthesis in tumor cells.
