Summary

• What is new: IDOLpro innovatively combines deep diffusion with multi-objective optimization for generating molecules, outperforming existing state-of-the-art models that fall short in optimizing multiple target physicochemical properties simultaneously.
• Why this is important: Current generative models in drug design do not effectively produce molecules that satisfy all desired physicochemical properties needed for effective drugs.
• What the research proposes: IDOLpro utilizes a novel generative chemistry AI to explore new chemical spaces and optimize for multiple key properties simultaneously using a deep diffusion model guided by differentiable scoring functions.
• Results: IDOLpro generates ligands with over 10% higher binding affinities compared to existing top solutions and is the first to surpass the performance of experimentally observed ligands in terms of binding on experimental complexes.
