Chemical Information
FooDB Name6-Methoxy-2(3H)-benzoxazolone
Description6-Methoxy-2(3H)-benzoxazolone, also known as 6-MBOA, belongs to the class of organic compounds known as benzoxazolones. These are organic compounds containing a benzene fused to an oxazole ring (a five-member aliphatic ring with three carbon atoms, one oxygen atom, and one nitrogen atom) bearing a ketone group. 6-Methoxy-2(3H)-benzoxazolone has been detected, but not quantified in, several different foods, such as red tea, alcoholic beverages, robusta coffees (Coffea canephora), tartary buckwheats (Fagopyrum tataricum), and rice (Oryza sativa). This could make 6-methoxy-2(3H)-benzoxazolone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 6-Methoxy-2(3H)-benzoxazolone.

anti pyretic35493 A drug that prevents or reduces fever by lowering the body temperature from a raised state. An antipyretic will not affect the normal body temperature if one does not have fever. Antipyretics cause the hypothalamus to override an interleukin-induced increase in temperature. The body will then work to lower the temperature and the result is a reduction in fever.DUKE
