Overview

DecompDiff is a diffusion model for structure-based drug design that decomposes the ligand molecule into two parts—arms and scaffold—and applies decomposed priors for 3D molecule generation within protein binding pockets.

By decomposing the molecular generation process, DecompDiff achieves higher-quality drug-like molecules with better binding affinity and pharmacological properties compared to monolithic generation approaches. The model generates 3D molecular conformations directly within the target protein's binding pocket, producing candidates ready for downstream docking and optimization.

Key Capabilities
  • Decomposed Generation

    Separate diffusion priors for scaffold and arms improve molecular quality

  • 3D Pocket-Aware Design

    Generates molecules directly within the target binding pocket

  • Bond Diffusion

    Explicit bond-type generation ensures valid chemical structures

  • Validity Guidance

    Sampling-phase guidance improves drug-likeness and synthetic accessibility

Applications
  • Hit Discovery

    Generate novel chemical matter for undrugged or challenging targets

  • Lead Optimization

    Explore structural modifications around known active scaffolds

  • Scaffold Hopping

    Discover new scaffolds that maintain binding pocket complementarity

  • Fragment-Based Drug Design

    Generate elaborated molecules from fragment hits using pocket context
