| Target | Gap-junction[1] |
| In Vitro | Tonabersat, a novel benzopyran derivative, inhibits cortical spreading depression (CSD) and therefore might be able to inhibit the early migraine mechanisms[1]. |
| In Vivo | Treatment with either Tonabersat (10 mg/kg) or Meclofenamate (20 mg/kg) as single agents significantly inhibit progression of metastatic lesions. Addition of carboplatin to either agent profoundly inhibits brain metastasis[2]. |
| Animal Admin | Mice[2] Athymic NCR nu/nu mice, Cr:NIH bg-nu-xid mice, B6129SF1/J, C57BL/6J-Tmem173gt/J 'golden ticket', and C57/Bl/6J mice are used at 5-6 weeks of age. For inducible knockdown experiments, mice are given doxycycline hyclate in the drinking water (2 mg/mL) and the diet 14 days after injection of cancer cells. For drug treatment experiments, mice are intraperitoneally injected with Carboplatin (5 mg/kg per 5 days), Tonabersat (MedChem Express) (10 mg/kg per day), or meclofenamic acid sodium salt (20 mg/kg per day). Vehicle (10% DMSO in polyethylene glycol 400) is used in control mice. Quantification of tumour burden is by Bio-luminescent imaging (BLI), performed using an IVIS Spectrum Xenogen instrument and analysed using Living Image software v.2.50. |
