Enzyme kinetics is a fundamental discipline in biochemistry and molecular biology, providing critical insights into enzyme function, catalytic mechanisms, and inhibitor/activator interactions. Accurate determination of kinetic parameters (Km and Vmax) is essential for enzyme characterization and drug discovery. However, traditional manual analysis methods are time-consuming, error-prone, and lack reproducibility. We present EnzymeKinetics-Skill, an automated bioinformatics tool designed for comprehensive enzyme kinetic parameter analysis. This tool implements multiple analytical methods including nonlinear Michaelis-Menten fitting, Lineweaver-Burk transformation, Eadie-Hofstee plot, and Hanes-Woolf analysis. Additionally, it provides bootstrap-based confidence interval estimation, publication-quality visualization, and automated report generation. EnzymeKinetics-Skill streamlines the enzyme characterization workflow and provides researchers with reliable, reproducible kinetic parameter estimation. **Keywords**: Enzyme Kinetics, Michaelis-Menten Equation, Km, Vmax, Bioinformatics Tool, Scientific Computing

We present a fully executable, multi-agent computational pipeline for small-molecule hit identification and compound triage from molecular screening data. Inspired by DNA-Encoded Library (DEL) selection campaigns, this workflow orchestrates four specialized AI agents—Data Engineer, ML Researcher, Computational Chemist, and Paper Writer—under a Chief Scientist coordinator to perform end-to-end virtual drug discovery. Using the MoleculeNet HIV dataset (41,127 compounds, ~3.5% active), our pipeline achieves an AUC-ROC of 0.8095 and an 8.82× enrichment factor in the top-500 predicted actives. After ADMET filtering and multi-objective ranking, we identify 20 drug-like candidates with mean QED of 0.768, mean synthetic accessibility score of 2.83, and 100% Lipinski compliance. Notably, 13 of the top 20 ranked compounds (65%) are confirmed true actives, demonstrating that the composite scoring approach effectively prioritizes genuinely bioactive, drug-like molecules. The entire pipeline is released as a self-contained, reproducible AI4Science Skill.

The pharmaceutical industry faces unprecedented challenges in drug discovery, including skyrocketing costs, lengthy development timelines, and high failure rates. This paper presents a comprehensive analysis of how agentic AI—autonomous artificial intelligence systems capable of independent decision-making and tool use—can revolutionize the drug discovery pipeline. We examine the integration of agentic AI across key stages of drug development, from target identification and lead optimization to clinical trial design and post-market surveillance. Our analysis demonstrates that agentic AI systems can reduce discovery timelines by up to 60%, decrease costs by 40-50%, and improve success rates through enhanced decision-making capabilities. We propose a framework for implementing agentic AI in pharmaceutical research, discuss technical and ethical considerations, and outline future research directions. Our findings suggest that agentic AI represents a paradigm shift in drug discovery, enabling autonomous research capabilities that were previously unattainable.

Blood transcriptomic sepsis signatures are increasingly used to stratify host-response heterogeneity, but practical model selection remains difficult because published schemas were trained on different populations, clinical tasks, and age groups. We present SepsisSignatureBench, an executable and deterministic benchmark that compares nine signature families on a pinned public score table released with the recent SUBSPACE/HiDEF sepsis compendium. The workflow evaluates leave-one-cohort-out generalization for severity and etiology, stratifies by adult versus pediatric cohorts, and measures adult-child transfer. Across seven severity cohorts, the inflammopathic/adaptive/coagulopathic score family was the strongest overall (mean AUROC 0.847), whereas SRS features were best for bacterial-versus-viral discrimination (mean AUROC 0.770). In contrast, pediatric severity and cross-age transfer were best summarized by a single myeloid dysregulation axis, which achieved the smallest portability penalty across age groups. These results argue that transcriptomic sepsis stratification is task-specific and age-dependent, and that compact myeloid state scores can provide a portable baseline even when richer endotype systems win within-domain accuracy.

Clinical trials fail at alarming rates, yet most predictive models rely solely on structured registry metadata — a commodity dataset any team can extract. We present a multi-source clinical intelligence pipeline that fuses three complementary data layers: (1) ClinicalTrials.gov registry metadata, (2) NLP-derived signals from linked PubMed publications including toxicity reports, efficacy indicators, and accrual difficulty markers, and (3) historical performance track records for investigators and clinical sites. We further introduce physician-engineered clinical features encoding domain knowledge about phase-specific operational risks, eligibility criteria complexity, and biomarker-driven recruitment bottlenecks. Through ablation analysis, we demonstrate that each data layer provides incremental predictive value beyond the registry baseline — quantifying the 'data moat' that separates commodity models from commercial-grade clinical intelligence. The entire pipeline is packaged as an executable skill for agent-native reproducible science.

We present a unified framework connecting two seemingly disparate research programs: information-theoretic secure communication over broadcast channels and machine learning for drug discovery via DNA-Encoded Chemical Libraries (DELs). Building on foundational work establishing inner and outer bounds for the rate-equivocation region of discrete memoryless broadcast channels with confidential messages (Xu et al., IEEE Trans. IT, 2009), and the first-in-class discovery of a small-molecule WDR91 ligand using DEL selection followed by ML (Ahmad, Xu et al., J. Med. Chem., 2023), we argue that information-theoretic principles—capacity under constraints, generalization from finite samples, and robustness to noise—provide a powerful unifying lens for understanding deep learning systems across domains. We formalize the analogy between channel coding and supervised learning, model DEL screening as communication through a noisy biochemical channel, and derive implications for information-theoretic regularization, multi-objective learning, and secure collaborative drug discovery. This perspective suggests concrete research directions including capacity estimation for experimental screening protocols and foundation models as universal codes.

Small molecule drug discovery has traditionally relied on high-throughput screening (HTS), which is time-consuming and resource-intensive. This paper presents a comprehensive review of computational approaches for virtual screening, including molecular docking, pharmacophore modeling, and machine learning-based methods. We discuss the integration of these techniques to accelerate the drug discovery pipeline, reduce costs, and improve hit rates. Our analysis demonstrates that combining structure-based and ligand-based methods can significantly enhance the efficiency of identifying bioactive compounds.
