Scalable Agentic Reasoning for Designing Biologics Targeting Intrinsically Disordered Proteins
This paper introduces StructBioReasoner, a scalable multi-agent AI system designed to tackle the 'undruggable' nature of Intrinsically Disordered Proteins (IDPs). By integrating advanced computational methods and leveraging HPC, it autonomously designs high-affinity biologics, addressing challenges in conformational heterogeneity and resource orchestration. Demonstrated success in identifying novel binders for crucial therapeutic targets like Der f 21 and NMNAT-2 positions StructBioReasoner as a foundational step towards exascale-driven drug discovery.

Unlocking IDP Therapeutics
Intrinsically disordered proteins (IDPs) are critical but challenging therapeutic targets due to their dynamic conformational ensembles. StructBioReasoner addresses this by providing an autonomous, scalable multi-agent system that can reason across complex biological landscapes and orchestrate diverse computational tools on HPC infrastructure. This represents a significant leap towards developing biologics for previously 'undruggable' targets.

Tournament-Based Agentic Reasoning
StructBioReasoner employs a novel tournament-based reasoning framework where specialized agents (e.g., Literature Explorer, Molecular Simulation, Binder Design, Optimization) compete to generate and refine therapeutic hypotheses. This distributed approach efficiently explores vast design spaces, leveraging domain knowledge, AI-structure prediction, molecular simulations, and stability analysis. Agents coordinate execution on HPC via the Academy middleware.
Computational Advances for IDPs
Recent breakthroughs, including diffusion models and frameworks like Logos, have enabled the design of high-affinity IDP binders. StructBioReasoner integrates these capabilities, determining when ensemble modeling is required and selecting appropriate tools. It unifies previously isolated methods into a coherent, autonomous workflow for end-to-end computational design tailored for IDPs' unique conformational heterogeneity.

Case Study: Der f 21 Allergen Targeting
StructBioReasoner was benchmarked against the house dust mite allergen Der f 21, a compact system with known epitopes. The framework achieved a remarkable 93.47% in silico design success rate. Out of 787 designed candidates, over 50% outperformed human-designed reference binders in terms of improved binding free energy. The system autonomously identified glutamate residue 7 (E7) as a key interaction residue, corroborating previous mutagenesis data.

NMNAT-2 Biologics Discovery
For the more challenging NMNAT-2 protein, StructBioReasoner successfully navigated a complex interactome to identify the NMNAT-2:p53 interface as a therapeutically relevant binding site. The system generated over 97,066 validated binder candidates and elucidated three major binding modes, including the well-studied NMNAT2:p53 interface. This demonstrates its capability to identify biologically meaningful design strategies autonomously.
Exascale Readiness & Scaling
StructBioReasoner demonstrates strong scaling characteristics on the Aurora supercomputer. The MD simulation agent achieved 80.4% efficiency at 256 nodes, and the binder design agent maintained 84.4% efficiency at the same scale. While I/O bottlenecks were identified beyond 256 nodes for certain agents, the multi-stage filtering architecture ensures the overall pipeline throughput is maintained. This work lays the foundation for autonomous scientific reasoning at exascale.
