This paper reports the synthesis and AMPA, Gly/NMDA, and KA receptor binding affinities of a new set of 1,9-disubstituted-8-chloro-pyrazolo[1,5-c]quinazoline-2-carboxylates 2-34. Binding data show that, in general, compounds 2-34 bind to the AMPA receptor with good affinity and selectivity. In particular, the obtained results indicate that the contemporary presence of a 1,2-dicarboxylic acid moiety
