| In Vitro | ZD7288 is a selective hyperpolarization-activated cyclic nucleotide-gated (HCN) channel blocker. ZD7288 inhibits glutamate release in a concentration-dependent manner. After incubation with 1, 5 and 50 µM ZD7288 for 24 hours, glutamate content in extracellular fluid is decreased to 69.0±2.8%, 31.4±2.0% and 4.4±0.3%, respectively (P<0.01, vs. DMEM/F12 group [100.2±4.2%]). After incubation with ZD7288 (25, 50, or 100 µM) for 20 minutes, 50 µM glutamate-induced [Ca2+]i rises are attenuated to 59.2±2.7%, 41.4±2.3% and 21.0±1.4%, respectively glutamate (P<0.01, vs. 50 µM glutamate group)[1]. |

| In Vivo | Application of ZD7288 0.1 µM at 5 minutes before high-frequency stimulation significantly decreases the amplitude of field excitatory postsynaptic potentials (fEPSPs), and this inhibitory effect is maintained throughout the recording period. Application of 0.1 µM ZD7288 30 minutes after high-frequency stimulation almost completely reverses the established long-term potentiation (LTP). Following application of ZD7288 (0.1 µM) 5 minutes before high-frequency stimulation, glutamate content is reduced to 74.9±8.0% (P<0.05, vs. normal saline group). Furthermore, application of 0.1 µM ZD7288 30 minutes after high-frequency stimulation markedly decreases the glutamate content to 77.0%±9.4% (P<0.05, vs. normal saline group)[1]. |

| Cell Assay | Primary hippocampal neurons are obtained from neonatal (1 to 2 day-old) Sprague-Dawley rats, and used in this study. The cells are incubated for 24 hours with ZD7288 (1, 5, or 50 µM), 8-bromoadenosine cyclic adenosine monophosphate (8-Br-cAMP, 5 or 50 µM), or forskolin (1 or 5 µM), and the culture medium is collected for glutamate measurement[1]. |

| Animal Admin | Specific-pathogen-free adult male Sprague-Dawley rats, aged 10 weeks and weighing 200±20 g are used in this study. For hippocampal administration of saline or drugs, a cannula is carefully inserted into the CA3 area with an introductory tube fixed parallel to the recording electrode, reaching 0.1 to 0.2 mm higher than the electrode tip. To test the effects of blockers on the induction of long-term potentiation (LTP), 0.1 µM ZD7288 or the monovalent cation cesium (Cs+) is applied 5 minutes before high-frequency stimulation. To test the effects of blockers on the maintenance of LTP, ZD7288/Cs+ is slowly administered using an infusion/withdrawal pump 30 minutes after the high-frequency stimulation[1]. |
