Abstract

We combined metadynamics, docking and molecular mechanics/generalised born surface area (MM/GBSA) re-scoring methods to investigate the impact of single and multiple N-methylation on a set of RGD cyclopeptides displaying different affinity for integrin αIIbβ3. We rationalised the conformational effects induced by N-methylation and its interplay with receptor affinity, obtaining good agreement with experimental data. This approach can be exploited before entering time-consuming and expensive synthesis and binding experiments.
