Cysteinyl leukotriene G protein-coupled receptors CysLT 1 and CysLT 2 regulate pro-inflammatory responses associated with allergic disorders. While selective inhibition of CysLT 1 R has been used for treating asthma and associated diseases for over two decades, CysLT 2 R has recently started to emerge as a potential drug target against atopic asthma, brain injury and central nervous system disorders, as well as several types of cancer. Here, we describe four crystal structures of CysLT 2 R in complex with three dual CysLT 1 R/CysLT 2 R antagonists. The reported structures together with the results of comprehensive mutagenesis and computer modeling studies shed light on molecular determinants of CysLTR ligand selectivity and specific effects of disease-related single nucleotide variants.
