A-317920

Catalog No.: A34192
H3R Antagonist
A-317920 is a selective and potent antagonist of the histamine H3 receptor (H3R), demonstrating a pKi value of 9.2 for the rat and 7.0 for the human H3R, reflecting over 130-fold selectivity for the rat receptor. This compound has been shown to enhance cognitive function through blockade of H3R activity. A-317920 is valuable for research focused on cognition, neuropharmacology, and the role of histamine receptors in the central nervous system.
