This paper proposes a novel approach to molecular optimization, a crucial stage in drug discovery. The existing methods primarily rely on external property predictors to guide iterative property optimization. However, learning all molecular samples in the vast chemical space is unrealistic for these predictors, leading to errors and noise during property prediction. This paper presents a text-guided multi-property molecular optimization method using a transformer-based diffusion language model (TransDLM). TransDLM leverages standardized chemical nomenclature as semantic representations of molecules and embeds property requirements into textual descriptions, preventing error propagation during the diffusion process. The approach retains core scaffolds of source molecules, ensuring structural similarities and enables simultaneous sampling of multiple molecules, making it ideal for scalable optimization through distributed computation.

This paper is about a new way to make medicine by changing chemical formulas. Right now, scientists have to use computer programs that guess what chemicals will do. But these programs can’t learn all the possible combinations of chemicals, so they often get things wrong. This new approach uses language models, like the ones that help you understand text on your phone, to optimize chemical formulas. It’s like having a super-smart lab assistant that helps find the best combination of chemicals for making medicine. This approach is better than other methods because it’s more accurate and can do many calculations at once.
