Hazard Information

Uses

LY3027788 hydrochloride, a diester analog of LY3020371 which is an mGlu2/3 receptor antagonist, is a potent and orally active prodrug of LY3020371. LY3027788 hydrochloride has antidepressant efficacy[1][2].

in vivo

LY3027788 (4.8-27 mg/kg; a single p.o.) produces antidepressant-like decreases in immobility times in the forced-swim test in mice^[1].
LY3027788 (4.8-16 mg/kg; a single p.o.) enhances the locomotor stimulant effects of quinpirole at the dose of 16 mg/kg in the locomotor activity assay in mice^[1].
LY3027788 (10-30 mg/kg; a single p.o.) dose dependently increases the wake time of rats without engendering rebound hypersomnolence^[1].
LY3027788 (a single p.o.) leads to the rapid and dose-proportionate appearance of the pharmacologically active species LY3020371 in plasma of both mouse (4.8-27 mg/kg) and rat (3-30 mg/kg)^[1].

Animal Model:	Male Sprague-Dawley mice (20-25 g)^[1]
Dosage:	4.8, 16, 27 mg/kg
Administration:	A single p.o. (60 minutes prior to testing)
Result:	Potent and efficacious with a minimal effective dose of 16 mg/kg in the mouse forced-swim assay. The ED₆₀ was 8.2 mg/kg.

IC 50
