Cnidilide is a natural product of alkylphthalein. Cnidilide can be isolated from the rhizomes of Cnidium officinale. Cnidilide reduces the production of NO and PGE2 by inhibiting the expression of iNOS and COX-2 induced by LPS (HY-D1056). Cnidilide can inhibit pro-inflammatory cytokines IL-1beta, IL-6, and TNF-alpha. Cnidilide can specifically inhibit the phosphorylation of p38 MAPK and JNK, as well as the activation of downstream kinase MSK-1. Cnidilide blocks the signaling pathway by inhibiting the transcriptional activity of AP-1 and NF-kappaB. can be used for research on inflammation conditions[1].
