LY487379 is a selective human mGluR2 positive allosteric modulator (PAM). LY487379 potentiates glutamate-stimulated [35S]GTPγS binding with EC50 values of 1.7 μM and >10 μM for mGlu2 and mGlu3 receptors respectively. LY487379 promotes cognitive flexibility and facilitates behavioral inhibition in a rat model. LY487379 can be used for schizophrenia research[2].
LY487379 (intraperitoneal injection; 30 mg/kg; injected 30 min before the test) requires significantly fewer trials to criterion during the ED phase of the ASST in attentional set-shifting task in male Sprague-Dawley rats. But there has no significant drug effect during any other discrimination stage[1].LY487379 hydrochloride (intraperitoneal injection; 10-30 mg/kg) induces an increase in microdialysate norepinephrine levels; the dose-effect resembled a bell-shape relationship increased. And it dose-dependently increases extracellular serotonin levels in the medial prefrontal cortex in male Sprague-Dawley rats[1].
