1) Researchers have created a new online resource called the IUPHAR/MMV Guide to Malaria Pharmacology (GtoMPdb) to curate information on antimalarial compounds and their molecular targets in Plasmodium. 2) The database currently contains 25 Plasmodium molecular targets and 57 antimalarial ligands that were manually curated from scientific literature. 3) A new customized online portal provides open access to the antimalarial data and allows browsing by parasite lifecycle stage, target species, and other features to help malaria research.

In 2017, there were an estimated 219 million cases of the disease leading to 435,000 deaths worldwide, with over 90% of these cases occurring in the WHO Africa Region1. In the last decade there has been a dramatic improvement in the drug discovery pipeline for antimalarial medicines leading to an expansion of the global portfolio2. New medicines are however urgently needed to combat increasing resistance to existing therapies. To foster innovation, it is crucial that results from drug discovery programmes and the scientific literature are evaluated and curated by experts in a single database. The IUPHAR/BPS Guide to Pharmacology (GtoPdb) has focused hitherto on the pharmacology and immunopharmacology associated with human non-infectious diseases3. We have recently been funded by Medicines for Malaria Venture (MMV), a non-profit organization, to curate antimalarial compounds and their Plasmodium molecular targets and to provide a new portal to the existing GtoPdb that is optimized for the malaria research community. The new resource, the IUPHAR/MMV Guide to Malaria Pharmacology (GtoMPdb), is freely available, richly annotated and will be regularly updated. GtoMPdb Data The latest database release (version 2019.2, 28th March 2019) contains: • 25 Plasmodium molecular targets • 57 ligands tagged as antimalarial All data are manually curated from the primary literature with guidance from our committee of scientific advisors4. Using our existing curation process5 we are able to resolve most published chemical structures to PubChem entries but some are found to be novel. We also assign UniProt IDs to evidence-supported Plasmodium target proteins. We submit all our curated antimalarial compounds, that include approved drugs, clinical candidates and research leads, to PubChem where they acquire GtoPdb- specific Substance Identifiers (SIDs). These currently merge into 57 Compound Identifiers (CIDs) that are fully searchable in PubChem. Of these: • 42 have active results in PubChem Bioassay • 48 have patent-extraction matches • 46 have vendor matches • 19 are approved drugs • Our SID entries are linked to 146 PubMed papers to provide tailored routes into browsing the antimalarial data. to provide tailored routes into browsing the antimalarial data. In addition, a new “whole organism” assay type has been introduced to capture data from the whole cell assays used routinely in antimalarial drug discovery.
