Arnicolide B
Arnicolide B is a sesquiterpene lactone. Arnicolide B is isolated from Centipeda minima. Arnicolide B inhibits the phosphorylation of ERK, JNK and p38 proteins in the MAPK signaling pathway. Arnicolide B reduces the production of inflammatory mediators NO, PGE2 and IL-6. Arnicolide B downregulates the overexpression of inflammatory proteins iNOS and COX-2. Arnicolide B has no effect on IκB-α degradation or NF-κB pathway activation. Arnicolide B is applicable to inflammation-related research.
