This hybrid peptide named colivelin was synthesized to potentiate the neuroprotective effect of humanin (HN). Colivelin is composed of Activity-Dependent Neurotrophic Factor (ADNF) C-terminally fused to AGA-(C8R) HNG17, a potent HN derivative. Colivelin completely suppresses cell death induced by overexpressed Familial Alzheimer's disease (FAD)-causative genes and beta-amyloid (1-43). Intraperitoneally administered colivelin suppresses memory impairment and might serve as a novel drug candidate for treatment of Alzheimer's disease.
