The Open PHACTS Explorer now uses version 1.3 of the Open PHACTS API. This includes an update of the pharmacology data (from ChEMBL 13 to ChEMBL 16).

Changes with this update:

• pChEMBL values (a unification over different activity types) are now available. They can be used to sort and filter data.
• The substructure and structural similarity search return a value judging the relevance of the identified structures.
• The Chemspider pop-up window is no longer available.
