(R)-(-)-α-Methylhistamine dihydrobromide is a highly potent and specific H3 histamine receptor agonist with a Kd of 50.3 nM. (R)-(-)-α-Methylhistamine dihydrobromide can cross the blood-brain barrier, and can enhance memory retention, attenuates memory impairment in rats. References: [1]. Arrang JM, et al.
