Full geometry optimizations, relaxed scans and transition structure searches were carried out with Gaussian 16 83 with the ONIOM 84 QM/MM method using the B3LYP hybrid functional 85 and 6-31 G(d) basis set with ultrafine integration grids for the QM part and the ff14SB 78 , gaff2 79 and TIP3P 86 force fields for the MM part (protein, substrate and water, respectively) with electrostatic embedding
Ipamorelin was characterised by Raun and colleagues ( European Journal of Endocrinology , 1998) as the first selective growth-hormone secretagogue, acting on the GHS-R1a receptor cloned by Howard and colleagues ( Science , 1996)
