CT-133

CT-133 is a selective and potent antagonist of the CRTH2 Receptor, with a Ki value of 2.2 nM, and exhibits a Ki greater than 3800 nM for the DP1 receptor. It inhibits PGD2-induced neutrophil migration and significantly reduces lung inflammation and improves lung function impairment in a mouse model of acute lung injury (ALI) induced by cigarette smoke. Additionally, CT-133 effectively suppresses the overexpression of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) and the chemokine (KC) while reversing the suppression of the anti-inflammatory factor IL-10. CT-133 is useful for ALI research.
