PepEVOLVE: Position-Aware Dynamic Peptide Optimization via Group-Relative Advantage

PepEVOLVE is a dynamic, position‑aware framework for optimizing macrocyclic peptides that learns where to edit and how to improve multiple properties. It enhances pretraining with dynamic masking and CHUCKLES shifting, employs a multi‑armed‑bandit router to identify high‑reward residues, and uses an evolving optimization algorithm with group‑relative advantage to stabilize updates. In in‑silico tests on a Rev‑binding macrocycle benchmark, PepEVOLVE surpassed PepINVENT, achieving higher permeability‑weighted scores and converging faster while respecting structural constraints.

Pepti-drift: Scalable Safe-Active Peptide Generation Without Inference-Time Guidance

Pepti-drift is a one‑step peptide generation framework that uses a single latent refinement and parallel decoding, avoiding costly inference‑time guidance. It incorporates attraction toward target‑specific binders and repulsion from liability‑associated regions, achieving an 18.37% predicted Safe‑Active yield across 88 held‑out targets. The method delivers competitive gains to multi‑property‑guided baselines while reducing generation cost by 468×, enabling scalable and fair high‑throughput peptide design.

PocketVE: Stable and Property-Guided Structure-Based Drug Design with Variance-Exploding Diffusion

PocketVE is a protein-pocket-conditioned variance‑exploding diffusion framework that integrates stable 3D coordinate denoising, classifier‑free property guidance, and adaptive protein perturbation. It improves 3D validity from 58.6% to 80.6% and reduces strain energy from 457.4 to 127.9 on CrossDocked2020 while maintaining competitive docking and property scores. The study shows moderate guidance balances target objectives with geometric quality, and diagnostics confirm enhanced pocket compatibility.

Don't Retrain, Just Reuse: Recovering Dual-Target Molecules from Single-Target Diffusion Models

arXiv:2605. 25681v2 Announce Type: replace-cross Abstract: Designing a single molecule that modulates two targets is a promising strategy for polypharmacology, but it remains substantially harder than standard single-target generation because one candidate must satisfy two binding requirements while preserving drug-likeness and synthesizability.

Multi-Objective Protein Optimization via Modular Diffusion Steering

The paper introduces MODS, a modular framework that performs multi‑objective protein optimization by steering diffusion models at inference time. MODS samples Chebyshev scalarization weights and a surrogate ensemble member to create a scalar steering reward, allowing the generation of sequences that balance multiple properties. After each batch of experimental evaluations, MODS updates its surrogates without retraining the generative model, and it achieves competitive hypervolume results across six protein optimization tasks, outperforming baselines on several.
