摘要

Peptide hormones are key signaling molecules secreted by endocrine cells that regulate vital physiological processes such as metabolism, growth, development, and reproduction. Advances in protein detection and computational approaches have led to the continuous identification of novel peptide hormones, highlighting their potential in basic research, clinical applications, and drug development. To support systematic studies in this field, we present HORDB 2.0, an open-access, manually curated dataset of peptide hormones. This dataset comprises 7,390 entries, including 7,307 peptide hormones and 83 peptide hormone drugs, corresponding to 372 marketed formulations. The dataset includes annotations on sequence, activity, structure, physicochemical properties, patents, clinical data, and literature references, where available. Additional parameters, including IC₅₀, EC₅₀, ED₅₀, and blood–brain barrier permeability, are also provided to facilitate peptide modification and drug design. HORDB 2.0 represents an expanded and enriched resource for peptide hormone research and therapeutic development, and may support downstream applications in endocrinology, pharmacology, and peptide-based drug discovery.
