narcolepsy

Pitolisant (Tiprolisant) is a selective and potent non-imidazole recombinant human histamine H3 receptor antagonist for the study of excessive daytime sleepiness and sudden collapse in patients with episodic narcolepsy.

Samelisant (SUVN-G3031) is a selective and inverse agonist of H3 receptor with Kis of 8.7 nM and 9.8 nM for human and rat. Samelisant has anticataplectic effects and can be used in studies about narcolepsy.

Almorexant (ACT 078573) is a potent and competitive dual orexin 1 receptor (OX1)/orexin 2 receptor (OX2) antagonist with Ki values of 1.3 and 0.17 nM for OX1 and OX2, respectively.

YNT-185 is a nonpeptide, selective agonist of the orexin type-2 receptor (OX2R), demonstrating EC50 values of 0.028 μM and 2.75 μM for OX2R and OX1R, respectively. Furthermore, YNT-185 effectively alleviates symptoms of narcolepsy-cataplexy in mouse models.

Firazorexton hydrate (TAK-994) is a brain-penetrant and orally active agonist of the orexin type 2 receptor (OX2R) with a potent EC50 of 19 nM. It effectively reduces wakefulness fragmentation and cataplexy-like episodes in mouse models of narcolepsy [1].

GSK 189254A is a histamine H3 receptor antagonist for the treatment of narcolepsy. Histamine H3 receptor antagonists have been shown to increase the release of neurotransmitters in the brain and to enhance cognition in vivo. The compound may also be usefu

CRL-40940 is a selective dopaminergic reuptake inhibitor

Potent and selective orexin OX2 receptor agonist (EC50 = 28 nM at human OX2 expressed in CHO cells). Displays approximately 100-fold selectivity for OX2 over OX1 (EC50 = 2.75 μM at human OX1 expressed in CHO cells). Depolarizes OX2-expressing histaminergic neurons in mouse brain slices. Increases wake time in wild type mice. Suppresses cataplexy-like symptoms in OX knockout mice. Nagahara et al (2015) Design and synthesis of non-peptide, selective orexin receptor 2 agonists.

Almorexant hydrochloride (ACT-078573 hydrochloride) is a potent and competitive dual orexin 1 receptor (OX1) orexin 2 receptor (OX2) antagonist with Ki values of 1.3 and 0.17 nM for OX1 and OX2, respectively.
