Biological Activity
Org-26576 (Org 26576) represents structurally a distinct chemical series derived from the first generation ampakine CX516 and displays 10-30 fold greater potency when compared to CX516 in potentiating AMPA-mediated electrophysiological responses with an EC50 of 8-16 μM in rat hippocampal primary cultured neurons. Org-26576 demonstrates selectivity for AMPA receptors when tested at 10 μM against >60 molecular targets including G-Protein Coupled Receptors, ion channels and kinases[1].

Protocol
Rats: Saline and Org-26576 (10 mg/kg) are administered, by intraperitoneal injection, 25 min before acute swim stress. Briefly, rats are subjected to a swim stress session for 5 min and sacrificed by decapitation 15 min after the end of the swim session. Brain regions are immediately dissected, frozen on dry ice and stored at -80°C[3].
Mice: Org-26576 (0.1, 1, 10 mg/kg) and Org 24448 (3, 10, 30 mg/kg) or vehicle (5% Mulgofenesaline) are administered intraperitoneally (i.p.) 10 min prior to the administration of the 14C-2-deoxyglucose. All drugs/vehicle are administered in the contralateral side of the abdomen to the 14C-2-deoxyglucose (2-DG) i.p. injection. A separate group of animals is also administered the AMPA receptor antagonist NBQX. NBQX (10 mg/kg) is injected either alone or 10 min prior to the administration of Org-26576 (10 mg/kg i.p.), Org 24448 (10 mg/kg i.p.) or vehicle (5% Mulgofenesaline i.p.). For each drug dose administered nZ5e7. The behavioural effects of all drugs administered are monitored throughout the entirety of procedure, and any alterations in behaviour noted[1].
