Overviews of the key features of a wide range of targets are provided on the summary view pages, with detailed view pages providing more in-depth information on the properties of a selected subset of targets. As of January 2018 the Medicines for Malaria Venture is supporting a new extension to develop the [http://www.guidetomalariapharmacology.org Guide to Malaria Pharmacology]. The core GtoPdb continues to be supported by the British Pharmacological Society.
