SIB 1553A is an agonist of nicotinic acetylcholine receptors (nAChRs) that displays selectivity for β4 subunit-containing receptors. Formulations containing SIB 1553A improve attentional function and performance in spatial and non-spatial working memory tasks in animals.

SIB 1553A hyrdrochloride is a novel cognitive enhancer with selectivity for neuronal nicotinic acetylcholine receptors (nAChR).
