The cysteinyl leukotrienes (CysLTs), leukotriene (LTC4), LTD4, and LTE4, mediate their actions through two distinct G protein-coupled receptors. LTD4 is the preferred ligand for the CysLT1 receptor, whereas LTC4 and LTD4 bind with approximately equal affinity to the CysLT2 receptor.{7174,8519} MK-571 is a selective, orally active CysLT1 receptor antagonist.{1501} It blocks the binding of LTD4, but not LTC4, to human and guinea pig lung membranes with Ki values of 0.22 nM and 2.1 nM, respectively, which is indicative of CysLT1 receptor-mediated activity in these preparations.{1501} MK-571 effectively blocks LTD4 activation of recombinant human and murine CysLT1 receptors{7174,10167} but is ineffective at blocking LTC4 or LTD4 activation of the recombinant human or murine CysLT2 receptors.{8519,10167}

    CAY10512 – 100 mg

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}
