Matcha: Multi-Stage Riemannian Flow Matching for Accurate and Physically Valid Molecular Docking

Read the original on arXiv Machine Learning →

Matcha is a new molecular docking method that refines ligand poses through three flow-matching stages—translation, rotation, and torsion—before applying GNINA for minimization, filtering, and ranking. It achieves high physical plausibility and is approximately 28 times faster than current large-scale co‑folding models, outperforming existing benchmarks. The authors provide code, benchmarking artifacts, and model checkpoints on GitHub and Zenodo.

Curriculum Learning for Generative Flexible Docking

The paper introduces a curriculum learning strategy for generative flexible docking, a task that predicts protein‑ligand complex configurations from an apo protein structure and a ligand SMILES string. By gradually incorporating examples with large conformational changes during training, the authors enhance an existing generative model, achieving a 46.52% top‑1 success rate on the PDBBind ESMFold apo benchmark and outperforming prior baselines. The approach leverages diffusion and flow‑based generative models to model the posterior distribution over ligand poses and protein conformations conditioned on the apo input.

FuseDiff: Symmetry-Preserving Joint Diffusion for Dual-Target Structure-Based Drug Design

FuseDiff is an end‑to‑end diffusion model designed for dual‑target structure‑based drug design, jointly generating a ligand graph and two pocket‑specific binding poses conditioned on both target pockets. It employs a message‑passing backbone with Dual‑target Local Context Fusion (DLCF) to fuse ligand atom contexts from both pockets, preserving symmetry while enabling expressive joint modeling. The model enforces topological consistency across the two poses and allows target‑specific geometric adaptation, achieving state‑of‑the‑art docking performance and enabling systematic assessment of dual‑target pose quality before docking‑based pose search.

ShallowBench: Benchmarking Generative Drug Design Models on Shallow-Pocket Targets

arXiv:2606. 06717v1 Announce Type: cross Abstract: While generative AI models have demonstrated remarkable success in structure-based drug design, they predominantly rely on deep binding pockets and struggle to sample effective ligands for challenging low-pocketability targets, such as the historically "undruggable" oncology targets KRAS and MYC.
