Sabcomeline (Memric; SB-202,026) is a selective M1 receptor partial agonist that was under development for the treatment of Alzheimer's disease.[1] It made it to phase III clinical trials before being discontinued due to poor results.

It is a non-selective agonist of all five muscarinic acetylcholine receptors with similar affinities.[2] However, functional selectivity for the M1 receptor has been claimed in vitro and in vivo.[2]
