Application

K-252a has been used:
  • as a tropomyosin receptor kinase (Trk) inhibitor to study the role of TrkA signaling in rats
  • as a Trk inhibitor for inducing in vitro injury in retinal Müller glial cells to study the effects of cord blood serum (CBS)
  • as a general protein kinase inhibitor to study its effect on in vitro human somatic testicular cell reassembly

Biochem/physiol Actions

K-252a is a selective inhibitor of tyrosine protein kinase. It targets a wide range of protein kinases with IC50 values between 3 and 25nM and the neurotrophin receptor-tropomyosin receptor kinase.

Oxidative stress and inflammation determine retinal ganglion cell degeneration, leading to retinal impairment and vision loss. Müller glial cells regulate retinal repair under injury, through gliosis. Meanwhile, reactive gliosis can turn in pathological effects, contributing to neurodegeneration. In the present

2,3,5,4'-Tetrahydroxystilbene-2-O-β-d-glucoside (THSG) is the major active ingredient in Plygonum multiflorum that displays a great deal of health-benefits including anti-oxidation, anti-hyperlipidemia, anti-cancer, anti-inflammation and neuroprotection. However, it is unclear whether THSG exerts neuroprotective functions by regulating neurotrophic factors and their associated

The major bioactive ingredient THSG of Polygonum multiflorum is well established for its anti-oxidation, anti-aging and anti-inflammation properties. Increasing evidence supports the capacity of THSG to ameliorate the biochemistry of neurotrophins and their downstream signaling axis in mouse models to
