What does isoxazole mean?

Medical Definition of isoxazole. 1 : a liquid heterocyclic compound C 3H 3NO isomeric with oxazole and having a penetrating odor like that of pyridine. 2 : a derivative of isoxazole.

Is furoxan an isoxazole?

Isoxazoles also form the basis for a number of drugs, including the COX-2 inhibitor valdecoxib (Bextra) and a neurotransmitter agonist AMPA. A derivative, furoxan, is a nitric oxide donor. An isoxazolyl group is found in many beta-lactamase-resistant antibiotics, such as cloxacillin, dicloxacillin and flucloxacillin.

Is isoxazole a heteroarene?
