Curation Updates

Since our 2021.2 update we have added over 70 new ligands. These have all been manually curated with chemical or peptide structures, links to external resources, general comments, notes on clinical development where appropriate, and target interaction data where this is available. We have also made update to over 40 existing ligand comments and clinical use summaries. Bioactivity comments have been updated on 10 ligands and 16 existing ligand have now been tagged as approved drugs.

Website Updates

  • New homepage (beta version) is available. This is a minor re-working of our homepage to prioritise the database search tools and access to ligand activity charts, immunopharmacology and malaria pharmacology.¬†
  • Added links from solute-carrier targets to the RESOLUTE – Solute Carrier Knowledgebase
