DesignMaster: A Multi-Conditional Diffusion Framework for Rational PROTAC Design.

DesignMaster achieves superior, constraint-aware PROTAC molecule generation by explicitly controlling linker length and physicochemical properties with a diffusion-based framework.

• Why it matters: Rational PROTAC design is hindered by limited structure-activity data and the complexity of linker conformations, making effective, drug-like molecule creation difficult.
• What they did: The approach uses an E(3)-equivariant graph Transformer with multi-condition fusion to incorporate key constraints during diffusion-driven molecular generation, tested on large PROTAC datasets.
• The result: DesignMaster outperforms existing methods in validity, uniqueness, and structural accuracy, demonstrating strong potential for practical, structure-guided PROTAC development.
