Chelidonic acid is a component of Chelidonium majus L., used as a mild analgesic, an antimicrobial, an acentral nervous system sedative. Chelidonic acid also shows anti-inflammatory activity. Chelidonic acid has potential to inhibit IL-6 production by blocking NF-κB and caspase-1. Chelidonic acid is a glutamate decarboxylase inhibitor, with a Ki of 1.2 μM.

How to use

In Vitro:

Chelidonic acid dose-dependently decreases IL-6 production at 0.1-10 μM, inhibits expression of IL-6 mRNA at 1-10 μM. Chelidonic acid (0.1-10 μM) decreases caspase-1 activation, nuclear NF-κB activation, and increases cytosol NF-κB activation. Chelidonic acid is a glutamate decarboxylase inhibitor, with a Ki of 1.2 μM. Chelidonic acid does not promote formation of apoenzyme or react with free pyridoxal-P.

In Vivo:

Chelidonic acid (0.2, 2 mg/kg p.o.) attenuates allergic reaction induced by ovalbumin in mice.
