WebMar 1, 2024 · Figure 3. Free energy perturbation (FEP)-guided scaffold hopping and hit-to-lead optimizations of 5-benzyl-2,3,4,6-tetrahydro-1 H -azepino [5,4,3- cd ]indol-1-ones as potent PDE5 inhibitors. 2. Results and discussion. 2.1. FEP-guided scaffold hopping strategy to discover potent PDE5 inhibitors with a novel scaffold. WebWe applied the free energy perturbation theory (FEP) to analyze two disease associated (A77T, D87G), and three non-classified (R108W, N142S, R179H), mutations. The calculated folding and binding free energy changes caused by mutations are shown in Table 1. It can be seen that the energy changes are predicted to be relatively small, being less ...
