Two aspects were looked at in this study. Firstly, we developed the search functionality for ChEMBL data to use RDF. For this, we took advantage of the RDF-ized ChEMBL knowledgebase (using the data from ChEMBL 02). Secondly, we developed a use case where compounds derived from ChEMBL are analyzed with the substructure mining software MoSS (see the Bioclipse Wiki). Here, we search for common and discriminative substructures within or between kinase families.
A second, more application-targeted Wizard was developed that primarily concentrates on retrieving compounds that bind proteins in a certain kinase family with a given activity type (see below). A histogram can be opened to visualize the distribution of activities. Lower and upper bound values can be selected, for focus, for example, only on that active compounds. A second, identical wizard page is provided to select a second dataset. This allows the user to set up a between-family data set. The saved data can then be used in the MoSS application to find the common and discriminative substructures (not shown).
Does this sounds interesting to you, or do like to give us feedback? Please send a note to email@example.com . Further details are provided in my blog!
