FG 7142 是一种非选择性苯二氮卓类反向激动剂，对含 α1 亚基的 GABAA 受体具有高亲和力，Ki为 91 nM。它还调节 GABA 诱导的 GABAA 受体上的氯离子通量，表达 α1 亚基，EC50为 137 nM。它可增加酪氨酸羟基化并导致小鼠大脑皮层中 β-肾上腺素受体的上调。

FG 7142 also modulates GABA-induced chloride flux at GABAA receptors expressing the α1 subunit (EC50= 137 nM). FG 7142 can increase tyrosine hydroxylation and cause upregulation of β-adrenoceptors in mouse cerebral cortex. FG 7142 , a non-selectively benzodiazepine inverse agonist, has high affinity for the α1 subunit-containing GABAA receptor (Ki=91 nM).

FG-7142 has a high efficacy in modulating GABA-induced chloride flux at GABAA receptors expressing the α1 subunit (EC50 = 137 nM) as compared to the other α subunits.FG-7142 has affinity for those expressing the α subunit, the Ki values are 91 nM; 330 nM; 492 nM and 2.150 μM for α1, α2,α3 and α5 subunits, respectively.

FG-7142 (intraperitoneal injection; 15 mg/kg) increases tyrosine hydroxylase activity and dopamine turnover in the medial prefrontal cortex and ventral tegmentum in vivo without effect in mesolimbic or nigrostriatal areas.FG-7142 (intraperitoneal injection; 15-30 mg/kg) activates mesolimbocortical dopaminergic projections, leading to increases in dopamine in the prefrontal cortex and the nucleus accumbens in rats.
