Uses

Almorexant Hydrochloride is an orally active orexin antagonist (OX1 and OX2 dual receptor antagonist) used in the treatment of insomnia.

Biological Activity

almorexant is an antagonist of orexin 1 receptor (ox1r) and orexin 2 receptor (ox2r) with kd values of 1.3nm and 0.17nm, respectively [1].almorexant is a dual ox antagonist. it inhibits the binding of orexin-a to both ox1r and ox2r with ic50 values of 6.6nm and 3.4nm, respectively. in the inositol phosphates assay, almorexant acts as a competitive antagonist of hox1r but a noncompetitive-like antagonist of hox2r. besides that, almorexant is found to block the increase in locomotor activity induced by icv orexin in c57bl/6 mice. furthermore, almorexant shows effects on sleep in multiple species, including man. it reduces the time spent awake and increased the time spent in nrem and rem sleep dose-dependently in normal c57bl/6 mice. these effects on sleep caused by almorexant are mediated by ox2rs as almorexant has no effect in mice lacking both ox1r and ox2r but has effects in mice lacking only ox1r [1, 2].
