Application

7,8-Dihydroxyflavone hydrate has been used as tropomyosin-receptor-kinase B (TrkB) agonist in mice[1][2] and to inhibit TrkB for monitoring evoked excitatory postsynaptic currents (eEPSCs).[3]

Actions biochimiques/physiologiques

7,8-Dihydroxyflavone (7,8-DHF) may be used to help identify and differentiate the physiological effects and cell signaling pathways mediated by TrkB activation, such as those involving, memory, vasorelaxation and hypertension.[4] 7,8-DHF elicits protection in scopolamine induced Alzheimer-like pathologic dysfunction.[5]
7,8-Dihydroxyflavone is a selective TrkB receptor agonist
7,8-Dihydroxyflavone is a selective tyrosine kinase receptor B (TrkB) receptor agonist. It manifests all the therapeutic effects of brain-derived neurotrophic factor (BDNF)—such as protecting neurons from apoptosis, inhibiting kainic acid-induced toxicity, decreasing infarct volumes in stroke, and neuroprotecting in an animal model of Parkinson′s disease—without the poor pharmacokinetic profile of BDNF limiting its therapeutic potential.

Questions

  1. What are the recommended storage conditions for D5446 after reconstitution?

    1 answer

    1. Although there is no datasheet available for product D5446, there is information available for a product sharing the same CAS number from a different division. Below is the information found for product 506300 (7,8 Dihydroxyflavone):

      - Solubility: DMSO (100 mg/ml)
      - Storage: Protect from light, +2°C to +8°C
      - Do Not Freeze: Ok to freeze
      - Special Instructions: Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.

      This information will also apply for product D5446. There are additional notes stating the product is packaged under inert gas. Therefore, if storing, it would be best to leave no air space in the storage container if possible. If that is not possible, it would be best to store under either dry nitrogen or argon.
