- Description
- Tetra-O-methylscutellarein is a bioactive component of Siam weed extract. It exhibits anti-inflammatory activity through inhibition of the NF-κB pathway. It suppressed IκB kinase complex alpha/beta (IKKα/β) and Inhibitory-kappa-B-alpha (IκBα), inhibiting p65 translocation and thereby suppressing COX-2 and iNOS expression. This compound is modulating bacterial resistance to antimicrobial drugs most probably via efflux pump inhibition. It also showed anti-mutagenic activity.
