  • Publication number: 20250099494
    Abstract: The present invention provides a phosphonic acid compound and a prodrug thereof, and preparation methods for and uses of the phosphonic acid compound and the prodrug thereof. Specifically, the present invention provides a compound of formula (I) or formula (I-A), wherein the compound of formula (I-A) is a prodrug form of the compound of formula (I). Upon experimental verification, the phosphonic acid compound of the present invention has good ENPP1 kinase inhibition activity, and can be used as a therapeutic agent for ENPP1-related diseases, and the phosphonic acid compound has good metabolic stability in-vivo. In addition, the phosphonate or amide prodrug compound provided by the present invention has relatively high oral bioavailability, and can overcome the defect that a phosphonic acid original drug compound cannot be taken orally.

  • Publication number: 20250022537
    Abstract: The present disclosure belongs to the technical fields of computational medicine and clinical oncology, and specifically relates to a molecular subtyping method for gastric cancer (GC) based on metabolic genes, a construction method for a prognostic prediction model and applications. In the present disclosure, metabolic process alterations are overall assessed, and new metabolic transcription patterns based on 456 metabolic gene-related signatures are identified. Three different metabolic patterns are validated by unsupervised consensus clustering analysis and independent datasets, and molecular and clinical pathological features of these three metabolite clusters have different metabolic gene expressions, pathway enrichments, gene variations, and survival outcomes.
