Israpafant

Israpafant (Y-24180) is a potent, selective and long-acting platelet activation factor (PAF) receptor antagonist with IC50s of 0.84 nM and 3.84 nM against PAF-induced human and rabbit platelet aggregation, respectively. Israpafant stimulates both extracellular Ca2+ influx and intracellular Ca2+ release in prostate cancer cells. Israpafant suppresses the allergic cutaneous reactions including eosinophilia, cytokine production, edema and erythema in mice[1][2].
