6-Methoxynaringenin is an aerial part of Scutellaria barbata D. Don (Lamiaceae) and inhibits NO production efficiently with an IC50 value of 25.8 μM.

AR-C102222 is a potent, selective iNOS inhibitor with IC50 of 35 nM, dislapys 3,000-fold and 20-fold selectivity over eNOS and nNOS respectively; reduces inflammation produced by the application of arachidonic acid to the ear, attenuates FCA-induced mechanical hyperalgesia, and attenuates acetic acid-induced writhing in mice.Rheumatoid ArthritisDiscontinued

Euscaphic acid has anti-diabetic, and anti-inflammatory activities, it inhibits LPS-induced inflammatory responses by interference with the clustering of TRAF6 with IRAK1 and TAK1, resulting in blocking the activation of IKK and MAPKs signal transduction to downregulate NF-κB activations.
