SB-674042

SB-674042 is a potent and selective non-peptide orexin 1 receptor (OX1R) antagonist (Kd = 5.03 and 3.76 nM in whole cell binding and membrane-based assays, respectively). In calcium mobilization studies, it was >100-fold selective for OX1 over OX2 and did not show significant affinity for serotonergic, dopaminergic, adrenergic, or purinergic receptors at concentrations up to 10 µM.Formal Name: [5-(2-fluorophenyl)-2-methyl-4-thiazolyl][(2S)-2-[(5-phenyl-1,3,4-oxadiazol-2-yl)methyl]-1-pyrrolidinyl]-methanone.
