生物活性

Irisflorentin, a naturally occurring isoflavone, is an abundant active constituent in Rhizoma Belamcandae. Irisflorentin markedly reduces the transcriptional and translational levels of inducible nitric oxide synthase (iNOS) as well as the production of NO. Anti-inflammatory activity[1].

体外研究
(In Vitro)

Irisflorentin does not affect the LPS-stimulated RAW 264.7 macrophages viability up to a concentration of 40 μM[1].
Irisflorentin (10-40 μM) inhibits the LPS-induced production of NO in a concentration-dependent manner without affecting the iNOS activity in RAW 264.7 macrophages[1].
Irisflorentin (10-40 μM) concentration dependently inhibits the LPS (10 ng/mL)-induced increase in iNOS mRNA expression in LPS stimulated RAW 264.7 macrophages. Irisflorentin (10-40 μM) concentration-dependently suppresses the production of TNF-α, IL-1β and IL-6 in LPS stimulated RAW 264.7 macrophages[1].
Irisflorentin (10-40 μM) concentration dependently inhibits the LPS (10 ng/mL)-induced increase in iNOS protein levels. Irisflorentin (10-40 μM) concentration-dependently suppresses LPS-induced p38 and ERK1/2 phosphorylation in a concentration-dependent manner, but slightly affects JNK phosphorylation[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
