Novel Ligand

Novel ligand discovery focuses on identifying small molecules that bind strongly and specifically to target proteins, a crucial step in drug development. Current research heavily utilizes machine learning, employing diverse architectures like convolutional neural networks, graph neural networks, and diffusion models to predict binding affinity, optimize ligand properties, and even generate novel ligand structures directly from protein pocket information. These advancements significantly accelerate the drug discovery process, improving efficiency and potentially leading to more effective therapeutics. The field also emphasizes improving the accuracy and generalizability of these models, particularly for novel protein targets and ligands, and incorporating protein flexibility into binding predictions.
