NS 638 is an inhibitor of the N-type voltage-gated calcium channel Cav2.2 and CNS L-type calcium channels.1 It inhibits potassium-induced calcium uptake in chick cortical synaptosomes (IC50 = 3.4 ?M) and AMPA-induced GABA release from primary chick cortical neurons (IC50 = 4.3 ?M), effects that can be blocked by the N-type calcium channel inhibitor ω-conotoxin GVIA but not the L-type calcium channel inhibitor nifedipine . It also inhibits potassium-induced calcium level increases in primary chick cerebellar granule cells (IC50 = 3.4 ?M), an effect that can be blocked by nifedipine but not ω-conotoxin GVIA. NS 638 (50 mg/kg) reduces infarct volume in a mouse model of focal ischemia induced by middle cerebral artery occlusion (MCAO) but not in a gerbil model of global ischemia induced by bilateral carotid artery occlusion (BCAO).

Cell experiment: | The effect of NS-638 on neuronal Ca2+-channels is evaluated using whole cell patch clamp techniques[1]. |
Animal experiment: | Mice: In the mouse middle cerebral artery occlusion model, NS-638 is administered i.p. (50 mg kg-1) at 1 h and 6 h post-ischemia, and once a day for the next two days[1]. |

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
