Talsaclidine (WAL-2014) is a selective full agonist of M1 muscarinic receptor, having partial agonist activity on the M2 and M3 subtypes (with no in vivo consequences). The general receptor profile of talsaclidine demonstrates a nearly specific interaction with muscarinic receptors, having only weak binding affinity for alpha1- and nicotinic receptors. The drug is being tested in phase III of clinical trials for the treatment of Alzheimer's disease.
