CRTH2-IN-1_product_DataBase

Bioactivity	CRTH2-IN-1 (Ramatroban analog) is a selective prostaglandin D2 receptor DP2 (CRTH2) antagonist with an IC50 of 6 nM in a human DP2 binding assay.
Invitro	CRTH2-IN-1 (Ramatroban analog, Compound 5) is a novel prostaglandin D2 receptor DP2 (CRTH2) antagonist with an IC50 of 7 nM in a human whole blood eosinophil shape change assay (hESC). CRTH2-IN-1 (Ramatroban analog) is a novel tricyclic antagonist of the prostaglandin D2 receptor DP2 (CRTH2) with efficacy in a murine model of allergic rhinitis. Human prostaglandin D1 receptor (hDP1) binding is performed using 3H-PGD2 and human platelet membranes. Human thromboxane receptor (hTP) binding performed using human platelet membranes and 3H-SQ-29,548. Human prostacyclin receptor (hIP) binding perfomed using hIP/293 membranes and 3Hiloprost. CRTH2-IN-1 inhibits hDP1 binding with an IC50 of 1μM. CRTH2-IN-1 inhibits hTP and hIP binding with IC50s of >100 μM. CRTH2-IN-1 inhibits human CYP isoforms CYP3A4, CYP 2C9 and CYP2D6 with IC50s of 7, 5 and >30 μM, respectively[1].
