Challenges of Connecting Chemistry to Pharmacology: Perspectives from Curating the IUPHAR/BPS Guide to PHARMACOLOGY

Connecting chemistry to pharmacology (c2p) has been an objective of GtoPdb and its precursor IUPHAR-DB since 2003. This has been achieved by populating our database with expert-curated relationships between documents, assays, quantitative results, chemical structures, their locations within the documents and the protein targets in the assays (D-A-R-C-P). A wide range of challenges associated with this are described in this perspective, using illustrative examples from GtoPdb entries. Our selection process begins with judgements of pharmacological relevance and scientific quality. Even though we have a stringent focus for our small-data extraction we note that assessing the quality of papers has become more difficult over the last 15 years. We discuss ambiguity issues with the resolution of authors’ descriptions of A-R-C-P entities to standardised identifiers. We also describe developments that have made this somewhat easier over the same period both in the publication ecosystem as well as enhancements of our internal processes over recent years. This perspective concludes with a look at challenges for the future including the wider capture of mechanistic nuances and possible impacts of text mining on automated entity extraction
