LY-404187 (3-10 nM) potentiates glutamate-evoked inward currents in human GluR4 transfected HEK293 cells[2].
LY-404187 (0.03-10 µM) selectively enhances glutamate-evoked currents through AMPA receptor/channels of acutely isolated pyramidal neurons with considerably greater potency (EC50=1.3±0.3 µM) and efficacy (Emax=45.3±8.0-fold increase) [3].
LY-404187 does not affect the magnitude or time course of wholecell K+ or Na+ currents in pre frontal cortex (PFC) pyramidal neurons at concentrations of 10 µM[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
LY-404187 (0.5 mg/kg; s.c. for 28 days) attenuates apomorphine-induced contraversive rotations and affords significant protection against the loss of tyrosine hydroxylase positive nigral cell bodies[4].
LY-404187 (0.1 or 0.5 mg/kg; s.c. for 14 days) affords functional, neurochemical and histological protection after infusion of 6-hydroxydopamine into the substantia nigra in rats[4].
LY-404187 (0.5 mg/kg; s.c. for 14 days) delayed treatment provides functional and histological improvement, suggesting a trophic action as administration is initiated after cell death[4].
LY-404187 (0.1 and 0.5 mg/kg; s.c. for 14 days) increases GAP-43 immunoreactivity in the striatum in a dose-dependent manner[4].
