By 1997, Ng and colleagues had identified the C-terminal segment of human GH as the primary region governing fat metabolism, and created AOD 9604 by adding a tyrosine residue to the fragment to enhance its stability

This inhibition preserves cellular NAD+ levels by reducing their consumption, simultaneously increasing GLUT4 transporter expression and activating sirtuin 1, known as the "longevity gene." The compound exhibits high membrane permeability and selectivity without affecting related methyltransferases or NAD+ salvage pathway enzymes, creating targeted metabolic effects while maintaining cellular safety

The retinal damage procedure included L-NAME administration in a total dose of 5 mg/kg, which was given by retrobulbar application in each eye, with 0.5 mg/0.1 ml saline per eye
