beta carbolines|Beta : Baguio β-Carboline alkaloids are a family of natural and synthetic products with structural diversity and outstanding antitumor activities. This review summarizes research developments of β-carboline and its derivatives as anticancer agents, which focused on both natural and synthetic monomers as well as dimers. 2. Extraction Methods of Antioxidants from Foods and Medicinal Plants. Extraction is the first and crucial step for studying the natural antioxidants from plants (Figure 1).Many extraction factors play important roles in the extraction efficiency, such as type and concentration of extraction solvent, extraction temperature, extraction time, and .

β-Carboline (9 H - pyrido [3,4- b] indole) represents the basic chemical structure for more than one hundred alkaloids and synthetic compounds. The effects of these substances depend on their respective substituent. Natural β-carbolines primarily influence brain functions but can also exhibit antioxidant [1] effects.
Beta-carboline compounds act as inverse agonists at the benzodiazepine site of the gamma-aminobutyric acid type A receptors and have actions entirely opposite to those of the anxiolytic benzodiazepines.beta carbolines β-Carboline alkaloids are a family of natural and synthetic products with structural diversity and outstanding antitumor activities. This review summarizes research developments of β-carboline and its derivatives as anticancer agents, which focused on both natural and synthetic monomers as well as dimers.β-Carboline alkaloids are a family of natural and synthetic products with structural diversity and outstanding antitumor activities. This review summarizes research developments of β-carboline and its derivatives as anticancer agents, which focused on both natural and synthetic monomers as well as dimers.Overview β- Carboline (9 H - pyrido [3,4- b] indole) is an organic amine that is the prototype of a class of compounds known as β- carbolines. Pharmacology β-carboline alkaloids are widespread in plants and animals, and frequently act as monoamine oxidase inhibitors (MAOI).
β-Carbolines (βCs) are naturally occurring bioactive alkaloids, whereas α-dicarbonyl compounds are reactive substances generated in foods and in vivo. In this work, l -tryptophan reacted with α-dicarbonyl compounds affording new β-carbolines.β-Carboline alkaloids are a remarkable family of natural and synthetic indole-containing heterocyclic compounds and they are widely distributed in nature. Recently, these alkaloids have been in the focus of interest, thanks to their diverse biological activities.
Harman and norharman, two neuroactive β-carbolines, are present in several plants and in thermally processed foods. They exhibited a wide spectrum of biological and pharmacological effects,.
