    A number of 5-oxo-pyrazolo[1,5-c]quinazolines (series B-1), bearing at position-2 the claimed (hetero)aryl moiety (compounds 1–8) but also a carboxylate group (9–14), were designed as hA3 AR antagonists. This study produced some interesting compounds endowed with good hA3 receptor affinity and high selectivity, being totally inactive at all the other AR subtypes. In contrast, the corresponding 5-ammino
