Аннотация:Diabetic neuropathy is one of the most common complications of diabetes mellitus (DM), occurring in 30-65% of patients. There are a lot of literature data concerning the important role of neurotrophins deficit in the pathogenesis of DM. However, the unsatisfactory pharmacokinetic properties of full-size neurotrophin impede its usage for the replacement therapy. Based on NGF 4th loop β-turn, a low-molecular weight NGF mimetic “GK-2” (hexamethylenediamine bis-(N-monosuccinyl-L-glutamyl-L-lysine)) was created in V.V. Zakusov Research Institute of Pharmacology. This compound as well as other low-molecular weight NGF and BDNF mimetics exert the activity under systemic administration and has no side effects of full-size neurotrophins. GK-2 demonstrated a pronounced neuroprotective activity in vitro and in vivo. The aim of this study is to evaluate effect of GK-2 on the model of diabetic neuropathy.
