Preincubation of the synaptosomes with AMN082 (1 μM) for 10 min before 4-aminopyridine treatment efficiently inhibits the 4-aminopyridine-evoked release of glutamate, without altering the basal release of glutamate.
AMN082 (6 mg/kg; p.o.) induces stress hormone increases in an mGluR7-dependent fashion in mGluR7
+/+
mice (C57BL/6 genetic background).
AMN082 (1.25-5.0 mg/kg, i.p.; 30 min before every Cocaine or Morphine injection during repeated drug administration or before Cocaine or Morphine challenge) dose-dependently attenuates the development, as well as the expression of Cocaine or Morphine locomotor sensitization.
| Animal Model: | Male Swiss mice (20-25g) |
| Dosage: | 1.25, 2.5, 5.0 mg/kg |
| Administration: | I.p.; given 30 min prior to Cocaine (10 mg/kg) or Morphine (10 mg/kg) challenge on day 17 or 20, respectively |
| Result: | Significantly attenuated the expression of Cocaine-induced locomotor sensitization; Attenuated the induction of Morphine-induced sensitization. |
