'Proximity frequencies' a new parameter to evaluate the profile of GABA

We reported the synthesis of new 8-methoxypyrazolo[1,5-a]quinazolines bearing an amide fragment at the 3-position. The final compounds, as aromatic (2a-i) and 4,5-dihydro derivatives (3a-i), have been evaluated in vitrofor their ability to modulate the chlorine current on recombinant GABA
