Description

H3R antagonist 1 hydrochloride is a histamine receptor 3 (H3R) inverse agonist extracted from patent WO2013107336A1, compound example 2.

IC₅₀ & Target

H₃ receptor

In Vitro

Treatment with H3R antagonist 1 hydrochloride, which is a H3R inverse agonist, promotes oligodendrocyte precursor cell (OPC) differentiation in a dose-dependent manner, at EC₅₀=25 nM. Western blot reveals a significant increase in expression levels of two markers of mature oligodendrocytes, myelin-associated glycoprotein (MAG) and myeline basic protein (MBP) in differentiating oligodendrocytes after treatment with H3R antagonist 1 hydrochloride, which suggests that treatment with H3R antagonist 1 hydrochloride drives more OPCs to differentiate. H3R antagonist 1 hydrochloride increases the Forskolin-stimulated cAMP level in the primary oligodendrocyte precursor cells in a dose-dependent manner^[1].

In Vivo

The ability of H3R antagonist 1 hydrochloride-1 to enhance in vivo remyelination is determined with the Cuprizone/Rapamycin-induced demyelination model. Mice are treated with Cuprizone diet combined with intraperitoneal injections of Rapamycin for 5 weeks followed by 9 days of compound administration. Cuprizone diet plus intraperitoneal injections of Rapamycin induced severe demyelination in both corpus callosum and cortex and treatment with H3R antagonist 1 hydrochloride (30 mg/kg, 9 days) significantly increases density of myelin specific Black-gold II staining in the lesion of corpus callosum and cortex in forebrain, compared to vehicle control group^[1].

Animal Administration
^[1]

Mice^[1]
The C57BL/6 mice at age of 8 weeks are fed with powder mouse food mixed freshly with 0.2% Cuprizone (w/w) and receive daily intraperitoneal injection of Rapamycin (10 mg/kg body weight) for 5 weeks to induce demyelination, then animals are allowed to recover (removal of Cuprizone from the diet and Rapamycin injection) and administrated with H3R-IN-1, at 30 mg/kg body weight orally, b.i.d. for an additional 9 days prior to sacrifice. The brain samples are collected for pathologic analysis^[1].
