Description_x000D_ Application_x000D_ LM22A-4 has been used as a component of dissociation medium for mouse embryonic stem cells (mESC) and human embryonic stem (hESC) aggregates._x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ LM22A-4 is a non-peptide and shares similarity with brain-derived neurotrophic factor (BDNF), especially in the loop2 region. It improves oligodendroglia density and favors myelin repair. LM22A-4 elevates the expression of protein kinase B (PKB or Akt) and extracellular signal-regulated kinases (ERKs). LM22A-4 elicits neuroprotection in spinal cord injury (SCI) by deregulating the cleaved-caspase-3 and favoring B-cell lymphoma 2(Bcl-2) expression._x000D_ LM22A-4 is a partial agonist of TrkB, a brain-derived neurotrophic factor (BDNF) receptor. In binding assays, LM22A-4 displaces BDNF with an IC50 of 47 nM. The compound restores TrkB phosphorylation and respiratory function in a mouse model of Rett syndrome.
