Safety Information
| Uses | Ombuin is a synthetic flavonoid which displays activity as a potent mycobacterium tuberculosis inhibitor. |
| Definition | ChEBI: Ombuin is a dimethoxyflavone that is quercetin in which the hydroxy groups at positions 7 and 4' are replaced by methoxy groups. Isolated from Cyperus teneriffae, it exhibits anti-inflammatory activity. It has a role as an anti-inflammatory agent and a plant metabolite. It is a trihydroxyflavone, a member of flavonols and a dimethoxyflavone. It is functionally related to a quercetin. It is a conjugate acid of a 7,4'-O-dimethylquercetin 3-olate. |
