In Vitro

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 (E_max=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.

In Vivo

LY-404187 (0.5 mg/kg; s.c for 11 days) can prevent MPTP-induced neurotoxicity in mice^[4].
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].

Animal Model:	Male C57BL/6J mice (20-25 g) are challenged with MPTP on day 8^[4]
Dosage:	0.5 mg/kg
Administration:	S.c; twice daily on weekdays and once daily at weekends for 11 days
Result:	Attenuated the loss of tyrosine hydroxylase immunoreactivity in the substantia nigra. No significant change in tyrosine hydroxylase immunoreactivity in the dorsal and ventral striatum.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
