Sumario:[Image: see text] A functional high throughput screen identified a novel chemotype for the positive allosteric modulation (PAM) of the muscarinic acetylcholine receptor (mAChR) subtype 5 (M(5)). Application of rapid analog, iterative parallel synthesis efficiently optimized M(5) potency to arrive at the most potent M(5) PAMs prepared to date and provided tool compound 8n (ML380) demonstrating modest CNS penetration (human M(5) EC(50) = 190 nM, rat M(5) EC(50) = 610 nM, brain to plasma ratio (K(p)) of 0.36).
