Isoxazole Usage And Synthesis

Description

Isoxazole, an important class of heterocycles, is a five membered heterocyclic compound that exhibits various pharmacological actions. It is present in some natural products such as ibotenic acid and is also used as a foundation for several drugs such as the COX-2 inhibitor valdecoxib and anti-inflammatory drugs. Isoxazoles are largely applied in the area of pharmaceuticals and therapeutics, including insecticidal, antibacterial, antibiotic, antitumour, antifungal, antituberculosis, anticancer and ulcerogenic. Besides, it has a great effect on reducing blood glucose, eliminating pain, resisting inflammation, killing harmful bacteria, controlling and reducing the risk of HIV.

Chemical Properties

A colorless liquid resembling pyridine. It is soluble in water at room temperature up to six times its volume.

Uses

Natural insecticide.

Definition

ChEBI: Isoxazole is a monocyclic heteroarene with a structure consisting of a 5-membered ring containing three carbon atoms and an oxygen and nitrogen atom adjacent to each other. It is the parent of the class of isoxazoles. It is a mancude organic heteromonocyclic parent, a monocyclic heteroarene and a member of isoxazoles.

Preparation

Isoxazoles can be synthesized by various methods, such as the 1,3-dipolar cycloaddition reaction of nitrile oxides with alkynes, the reaction of hydroxylamine with 1,3-diketones or propiolic acid derivatives, etc.

General Description

Isoxazole(288-14-2) are described as inhibitors of acetylcholinesterase (AChE). Isoxazole ligands bind to and inhibit the Sxc- antiporter.

Hazard

Narcotic and psychomimetic effects.
