产品描述 | (R)-(-)-α-Methylhistamine dihydrobromide is a potent and selective agonist of H3 histamine receptor( Kd of 50.3 nM). |
靶点活性 | H3 receptor:50.3 nM (kd) |
体外活性 | (R)-(-)-α-Methylhistamine dihydrobromide is an H3-agonist that is > 10 times as potent as histamine (HA).(R)-(-)-α-Methylhistamine dihydrobromide has only weak affinities for H1 and H2 receptor with a pKi=4.8 and < 3.5, repectively. Its selectivity toward H3-receptors is > 1,000 times as high as that of HA. (R)-(-)-α-Methylhistamine dihydrobromide displays >200-fold selectivity over H4 receptors[1]. |
体内活性 | (R)-alpha-Methylhistamine dihydrochloride (6.3 mg/kg; i.p.) significantly decreases the steady-state t-MH level in the mouse brain, whereas these compounds produced no significant changes in the HA level[2].Pretreatment with (R)-(-)-α-Methylhistamine dihydrobromide reverses propofol‐induced memory retention[4]. |
