This workflow downloads ligand data for hepatic Organic Anion Transporting Polypeptides (OATPs) from five different open sources (CHEMBL, Metrabase, USFC-FDA Transportal, IUPHAR, and Drugbank) in an semi-automatized fashion. This workflow can be adopted to any other ligand data showing an (in)activity against membrane transporter. If missing, structural file format is mapped via PubChem webservices. Pre-curated compounds are subjected to standardization procedure (Atkinson standardization scr...
