New 3-aryl-6-(3-thienyl)pyrazolo[1,5-a]pyrimidin-7-ones (2a-j) are synthesized and evaluated in vitro on Bz/GABA(A) receptors and on recombinant benzodiazepine receptors (alpha x beta 2/3 gamma 2; x = 1-3, 5) expressed in HEK293 cells. SAR studies on the new compounds are conducted and molecular modeling is accomplished to better investigate requirements leading to subtype selectivity. Some of the

GABA(A)受体和
重组苯并二氮杂receptor受体上进行了体外评估(在HEK293细胞中表达的alpha x beta 2/3 gamma 2; x = 1-3,5)。对新化合物进行了
SAR研究,并完成了分子建模,以更好地研究导致亚型选择性的要求。体内测试了一些合成的化合物,以探索其药理作用,这是由于在体外观察到的其高α1β2gamma 2亚型选择性的结果。
