实验参考方法

Cell experiment:

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 experiment:

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].

产品描述

ZD 7288 is an inhibitor of hyperpolarization-activated cyclic nucleotide-gated (HCN) channel [1].

The HCN channel is found in the sinoatrial node (SAN) and is permeable to both Na+ and K+. The HCN current exists in neurons under hyperpolarization of the cell membrane and plays an important role in neuropathic pain [1].

In CA1 pyramidal cells from Wistar rats, ZD 7288 inhibited T-type Ca2+ channel currents in a concentration-dependant way [2]. In neonatal rat facial motoneurones, ZD-7288 (0.1-10 μM) inhibited the hyperpolarisation-activated current with IC50 value of 0.2 μM in a time- and voltage-dependent way [3]. In CA1 pyramidal neurons, ZD 7288 (1-1000 μM) inhibited the hyperpolarization-activated current. However, ZD 7288 had no influence on long-term depression (LTD) of the CA3-CA1 synapse [4].

In rats with chronic visceral pain, ZD 7288 (50-100 nM) significantly inhibited abdominal withdrawal reflex (AWR) scores and electromyographic (EMG) responses. Also, ZD 7288 significantly increased pain thresholds. These results suggested that spinal HCN channels might play a critical role in chronic visceral pain [1].
