Ifetroban

Ifetroban (BMS-180291) is an orally active antagonist of thromboxane A2 (TXA2) or prostaglandin H2 (PGH2) receptor. Ifetroban shows antiplatelet activity, and inhibits tumor cell migration without affecting cell proliferation. Ifetroban can be used for myocardial ischemia, hypertension, stroke, thrombosis, cardiomyopathy research^[1][2][3][4]. IC50 & Target: Thromboxane A2 receptor; Prostaglandin H2 receptor^[4] In Vitro: Ifetroban (CPI211) (100 nM; 48 h) results Tpr inhibition and potently blocks spontaneous metastasis from primary tumors, without affecting tumor cell proliferation, motility, or tumor growth in 4T1 cells (mouse mammary cancer)^[2].
Ifetroban (100 nM; 6 h) strongly inhibits PKC substrate phosphorylation, and blocks agonist (U46619, HY-108566)-induced TPr diminution in human umbilical vein endothelial cells (HUVECs)^[2].
In Vivo: Ifetroban (50 mg/kg/d; p.o.; 2 d prior to, through 28 d after tumor injection) decreases hematogenous metastasis of multiple cancer types without in mice model^[2].
Ifetroban (50 mg/kg/d; p.o.; 12 d) does not affect primary tumor growth but decreases tumor vessels in mice with 4T1 (mouse mammary cancer)^[2].
Ifetroban (BMS 180,291; 1 and 3 mg/kg, p.o.) inhibits aggregation and antagonizes TP-receptor in monekys. Ifetroban (3 mg/kg, i.v.) causes only marginal and transient hemodynamic effects in anesthetized African green monkeys^[3].
