Abstract

The synthesis and structure-activity relationship (SAR) of a novel series of aryl piperazine napthyridinone D(2) partial agonists is described. Our goal was to optimize the affinities for the D(2), 5-HT(2A) and 5-HT(1A) receptors, such that the D(2)/5-HT(2A) ratio was greater than 5 to ensure maximal occupancy of these receptors when the D(2) occupancy reached efficacious levels. This strategy led to identification of PF-00217830 (2) with robust inhibition of sLMA (MED=0.3mg/kg) and DOI-induced head twitches in rats (31% and 78% at 0.3 and 1mg/kg) with no catalepsy observed at the highest dose tested (10 mg/kg).
