Galmic
Galmic is a selective non-peptide GalR1-selective galanin receptor agonist that crosses the blood-brain barrier, with a human Ki of 34.2 μM. Galmic can be used for research on status epilepticus and epilepsy.
For research use only. We do not sell to patients.

In Vivo
Galmic (2.45-9.8 µmol/kg; intraperitoneal injection; once; 15 minutes before formalin injection) inhibits formalin-induced licking behavior in mice in a dose-dependent manner[1].
Galmic (15 mg/kg; intraperitoneal injection; once; 40 minutes before the forced swimming test) increases active behavior in rats in the forced swimming test[1].
Galmic (15 mg/kg; intraperitoneal injection; once; 40 minutes before the open field test) reduces locomotor activity in rats in the open field test[1].
Galmic (systemic administration) effectively inhibits seizures induced by perforant pathway stimulation[2].
Galmic (systemic administration) effectively inhibits Pentylenetetrazole-induced seizures[2].

Animal Model:Wistar (male, adult)[1]
-
Dosage:0.02 nmol (intrahippocampal, 10 min after stimulation);0.1 nmol (intrahippocampal, 10 min after stimulation); 1 nmol (intrahippocampal, 10 min after stimulation); 5 nmol (intrahippocampal, 10 min after stimulation); 5 nmol (intrahippocampal, 60 min after stimulation); 10 nmol (intrahippocampal, 60 min after stimulation); 1 mg/kg (i.p., 10 min after stimulation); 2 mg/kg (i.p., 10 min after stimulation)
-
Administration:intrahippocampal once 10 min after stimulation; intrahippocampal once 60 min after stimulation; i.p. once 10 min after stimulation
-
Result:At 0.1 nmol, SSSE duration was 1-2 h versus 10-12 h in controls; effects were stronger at 1 and 5 nmol.
At 5 nmol, seizures were abolished within 5-10 min and spikes within 2 h.
During maintenance, 5 and 10 nmol attenuated SSSE; 10 nmol shortened SSSE duration to 4-5 h, time spent in seizures to 20-40 min, and spike duration to under 8 h versus 24 h in controls.
At 2 mg/kg i.p., self-sustaining seizures were attenuated, whereas 1 mg/kg i.p. had no effect.

Animal Model:C57BL/6 (male, 25-30 g)[1]
-
Dosage:2.45 µmol/kg (i.p., 15 min before formalin); 4.9 µmol/kg (i.p., 15 min before formalin); 9.8 µmol/kg (i.p., 15 min before formalin)
-
Administration:i.p.; once; 15 min before formalin
-
Result:Produced dose-dependent inhibition of both phase 1 and phase 2 flinching.
The ED50 for inhibition of phase 1 was 2.9 µmol/kg (95% CI 2.1-4.1), and for phase 2 was 3.7 µmol/kg (95% CI 2.6-5.2).

-
Result:Increased time spent active by 55% relative to vehicle-treated rats.
-
Animal Model:Rats[1]
-
Dosage:15 mg/kg
-
Administration:i.p.; once; 40 min before open-field test
-
Result:Reduced total squares crossed by more than half relative to vehicle-treated rats.
