Quin-C7
Based on 1 Customer Validation
Quin-C7 is an orally active FPR2/ALX antagonist. Quin-C7 binds to the orthosteric ligand-binding pocket of FPR2/ALX, modulates receptor activation, and inhibits pro-inflammatory ERK signaling mediated by serum amyloid A (SAA). Quin-C7 reduces pro-inflammatory mediators TNF-α levels, increases anti-inflammatory IL-10, decreases inflammatory neutrophils and pro-inflammatory M1 macrophages, downregulates ERK1/2 phosphorylation, and upregulates JNK1/2/3 phosphorylation. Quin-C7 blocks FPR2/mFpr2 signaling, reduces brain lesion volume. Quin-C7 can be used for the research of inflammatory bowel disease and neuromyelitis optica spectrum disorder.
