WebMar 23, 2024 · However, these methods rely on the structural features of the molecules used to generate the model and often fail in correctly predicting new chemical scaffolds. Recently, the 3D structure of hERG channel has been experimentally solved enabling the use of structure-based (SB) strategies which may overcome the limitations of the LB approaches. Webrdkit's 3d coord generation algorithm was designed for small- to medium-sized "druglike" molecules, so you may expect it to fail in areas very far from this territory. For example, it does not work well for long conjugated oligomers - sometimes it produces molecular knots instead of straight strands, and is quite slow for large systems. philly connection atlanta gaWebJul 28, 2024 · Starting from a SMILES file you can embed a conformation to your molecule (e.g. calculate its 3D coordinate), minimize it and then save the mol object in PDB format … philly connection altamonte springs
