CovInter 2.0: Comprehensive Molecular Interactome of Coronavirus Infection.

The ongoing evolution of coronaviruses (CoVs) poses a long-term threat to global public health, requiring dissection of virus-host interactions to develop broad-spectrum antivirals. Existing data resources are often limited to specific interaction types, hindering a systematic understanding of the complete viral life cycle. To address this, CovInter 2.0 (https://idrblab.org/COVINTER) has been developed as a comprehensively upgraded database of coronavirus interactomics, which is the first to systematically integrate the six major classes of molecular interactions that drive the viral life cycle, compiling over 61,000 entries. Furthermore, data for 229 potential anti-CoV drugs and their targets have been included, bridging molecular interactions with therapeutic development. The platform features an interactive network visualization tool for intuitive exploration of these complex relationships. As an open-access resource, CovInter 2.0 provides a powerful tool for virology and drug discovery, computational biology, designed to accelerate the identification of novel antiviral targets and the development of next-generation therapeutics.
