Molecular FormulaC15H11ClF3N3
CAS No.150493-34-8
ProtocolIn VitroNS-638 dose dependently inhibits K+-stimulated [45 Ca2+]-uptake in chick cortical synaptosomes and 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid (AMPA)- stimulated [3H]GABA-release from cultured cortical neurons with IC50 values of 2.3 and 4.3 μM, respectively. K+-stimulated intracellular Ca2+-elevation in cultured cerebellar granule cells is equipotently blocked with an IC50 value of 3.4 μM. At this concentration no effect on Ca2+-induced contractions in K+-depolarized guinea pig taenia coli is observed. NS-638 reversibly blocks N- and L-type Ca2+-channels in cultured chick dorsal root ganglion cells in the concentration range of 1-30 μM
In VivoIn the mouse middle cerebral artery occlusion model, NS-638 administered i.p. (50 mg kg-1) at 1 h and 6 h post-ischemia, and once a day for the next two days, results in a 48% reduction in total infarct volume. It does not show protection against ischemic neuronal damage in the gerbil model of bilateral carotid artery occlusion

Calculation Results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid concentration mg/mL) ,Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
