Screening a compound library of quinolinone derivatives identified compound 11a as a new P2X7 receptorantagonist. To optimize its activity, we assessed structure-activityrelationships (SAR) at three different positions, R1, R2 and R3, of the quinolinone scaffold. SAR analysis suggested that a carboxylic acid ethyl ester group at the R1 position, an adamantyl carboxamide group at R2 and a 4-methoxy
