BayCysLT2
BayCysLT2, an isophthalic acid derivative, is a selective and potent CysLT2 receptor antagonist [1].
Cysteinyl leukotrienes (CysLTs) belong to a family of G protein-coupled receptors (GPCRs). The cysteinyl leukotrienes (CysLTs) are inflammatory mediators associated with neuronal injury after brain ischemia through the activation of their receptors, CysLT1R and CysLT2R [2].
In vitro: BayCysLT2 inhibited radioligand binding of LTD4 to CysLT2 and CysLT1 receptor cell lines with IC50 values of 35 and >10,000 nM, respectively [1]. BayCysLT2 reversed LTC4-stimulated perfusion pressure increase and contractility decrease in isolated Langendorff-perfused guinea pig hearts in a concentration-dependent manner [1]. BayCysLT2 protected astrocytes from ischemic injury [3].
In vivo: BayCysLT2 attenuated myocardial infarction damage but also inhibited LTD4-induced Evans blue dye leakage in the mouse ear vasculature [4].
