N2 - (±)-cis-2-Methyl-spiro(1,3-oxathiolane-5,3′)quinuclidine (AF102B), a new muscarinic agonist of utmost rigidity, exhibits a high selectivity for M1 muscarinic receptors. In rats having a cholinergic hypofunction induced by the intracerebroventricular administration of ethylcholine aziridinium (AF64A), AF102B reversed cognitive impairments in a step-through passive avoidance task and in an 8-arm radial maze. AF102B reversed cognitive impairments at significantly lower doses than those needed to induce side-effects. In addition, AF102B exhibited low toxicity. The results suggest that AF102B may prove useful for treatments of cholinergic deficiencies and cognitive impairments, like those reported in Alzheimer's disease.
