GE1111 is a MRGPRX2 antagonist (IC50 = 9.4 µM). GE1111 inhibits MRGPRX2/MRGPRB2-mediated mast cell activation. GE1111 reduces the expressions of TSLP, IL-13, MCP-1, TNF-alpha, IL-1beta and periostin, maintains the expression levels of claudin 1 and involucrin, restores the phagocytic activity of macrophages, and attenuates the activation of STIM1 and phosphorylated AKT. GE1111 exerts anti-inflammatory and anti-allergic effects in multiple animal models. GE1111 is applicable to the research related to rosacea, atopic dermatitis and ulcerative colitis[1][2][3].
