Description: Potent and selective non-peptide OX1 antagonist
Chemical Name: [5-(2-Fluorophenyl)-2-methyl-4-thiazolyl][2(S)-2-[(5-phenyl-1,3,4-oxadiazol-2-yl)methyl-1-pyrrolidinyl]methanone
Biological Activity
Potent and selective non-peptide orexin OX1 receptor antagonist (Kd = 3.76 nM). Exhibits 100-fold selectivity for OX1 over OX2 receptors. Has no effect at serotonergic, dopaminergic, adrenergic or purinergic receptors. Inhibits orexin 1-induced Ca2+ mobilization in CHO-DG44 cells stably transfected with the OX1 receptor.
Licensing Information
Sold for research purposes under agreement from GlaxoSmithKline.
