Background:

Colivelin is a neuroprotective peptide and activator of STAT3.

Colivelin is a hybrid peptide composed of ADNF and AGA-(C8R)HNG17, a potent Humanin (HN) derivative[2]. Humanin (HN) and its derivatives, such as Colivelin (CLN), suppress neuronal death induced by insults related to Alzheimer's disease (AD) by activating STAT3[1]. Colivelin completely suppresses death induced by overexpressed FAD-causative genes and A 1-43 at a concentration of 100 fM, whereas AGA-(C8R)HNG17 does so at a concentration of 10 pM[2].

Humanin (HN) and its derivatives, such as Colivelin (CLN) also ameliorate functional memory impairment of mice induced by anticholinergic drugs or soluble toxic amyloid-β (Aβ) [1]. Intracerebroventricular administration of Colivelin not only completely suppresses impairment in spatial working memory induced by repetitive intracerebroventricular injection of Aβ25-35 or Aβ1-42, but also it antagonizes neuronal loss in the CA1 region of hippocampus induced by hippocampal injection of Aβ1-42[2].
