A series of novel pyridazone and pyridone compounds as γ-secretase modulators were discovered. Starting from the initial lead, structure−activity relationship studies were carried out in which an internal hydrogen bond was introduced to conformationally fix the side chain, and compounds with improved in vitro Aβ42 inhibition activity and good Aβtotal/Aβ42 selectivity were quickly discovered.
