*3.3. Humanin Analogs*

Amino acid substitutions in Humanin have led to the development of synthetic Humanin analogs, which are more potent than the endogenous Humanin. Humanin G (HNG) is formed by a Ser to Gly amino acid substitution at position 14. HNGF6A is formed by the Phe to Ala amino acid substitution at position 6 [30].
