Ramatroban 生物活性

描述 Ramatroban is a selective thromboxane A2 (TxA2, IC50=14 nM) antagonist, which also antagonizes CRTH2 (IC50=113 nM) by inhibiting PGD2 binding. Ramatroban also inhibits human CYP isoform CYP2C9 with an IC50 of 15 μM[3]. Ramatroban, a small-molecule antagonist of DP2 and TP receptors, reverses viremia-associated proinflammatory, immunosuppressive5 and prothrombotic processes which are similar to those induced by SARS-Cov-2[4]. Ramatroban, a dual CRTH2/thromboxane-like prostanoid receptor antagonist, markedly inhibited Th2 cytokine production induced by PGD2, while the selective thromboxane-like prostanoid receptor antagonist SQ29548 was without effect[5]. Ramatroban significantly alleviated silica-induced pulmonary inflammation, fibrosis, and cardiopulmonary dysfunction compared with the control group[6]. Ramatroban similarly inhibited asthma pathology in vivo by reducing peribronchial eosinophilia and mucus cell hyperplasia[7].
