Biological Activity

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].
