The consequences of these modifications are that IGF-1 LR3 retains the pharmacological activity of IGF-1 as an agonist of the IGF-1 receptor, has very low affinity for the insulin-like growth factor-binding proteins (IGFBPs), and has improved metabolic stability resulting in approximately three times greater potency than IGF-1, with a significantly longer half-life of about 2030 hours relative to IGF-1s half-life of about 1215 hours
Energy minimization was conducted with the steepest descent method (maximum force tolerance of 1000 kJmolnm, step size 0.01 nm), followed by 100 ps NVT equilibration (0310.15 K) and 100 ps NPT equilibration (310.15 K, 1 bar) using the Berendsen barostat
