Positive allosteric modulator of nicotinic α4β2 receptors; selectively increases the ionic current through α4β2 in the presence of ACh. Displays 14.7-fold selectivity for α4β2 over homomeric (α7) receptors. Moderately cytotoxic in HCT-116 cells. Also inhibits human muscle (αβεδ) and Torpedo (αβγδ) nAChRs (IC50 values are 1.0 and 0.1 μM, respectively) by binding in the ion channel. Purity 98%. MW (observed): 357.72
