About AstraZeneca
• Alongside our own R&D, we partner with others, combining skills and resources to broaden the potential for successful innovation.
• We believe that only by working together with others who have a part of play in improving healthcare can real progress be made.
• We work closely with others in the healthcare community, including physicians and those who pay for healthcare, to understand their challenges and how we can combine skills and resources to achieve a common goal: improved health.

Länkade Data i Läkemedelsforskningen
Två exempel på hur AstraZeneca arbetar med europeiska forskningssamarbeten och internationella standard organisationer för att göra kemidata och kliniska studie data enklare att använda med hjälp av nästa generations web teknik.

“Find me compounds that inhibit targets in NFkB pathway assayed in only functional assays with a potency <1 μM”
“What is the selectivity profile of known p38 inhibitors?”
“Let me compare MW, logP and PSA for known oxidoreductase inhibitors”
Number sum Nr of 1 Question
15 12 9 All oxidoreductase inhibitors active <100nM in both human and mouse
18 14 8Given compound X, what is its predicted secondary pharmacology? What are the on and off,target safety concerns for a compound? What is the evidence and how reliable is that evidence (journal impact factor, KOL) for findings associated with a compound?
24 13 8Given a target find me all actives against that target. Find/predict polypharmacology of actives. Determine ADMET profile of actives.
32 13 8 For a given interaction profile, give me compounds similar to it.
37 13 8The current Factor Xa lead series is characterised by substructure X. Retrieve all bioactivity data in serine protease assays for molecules that contain substructure X.
38 13 8Retrieve all experimental and clinical data for a given list of compounds defined by their chemical structure (with options to match stereochemistry or not).
41 13 8
A project is considering Protein Kinase C Alpha (PRKCA) as a target. What are all the compounds known to modulate the target directly? What are the compounds that may modulate the target directly? i.e. return all cmpds active in assays where the resolution is at least at the level of the target family (i.e. PKC) both from structured assay databases and the literature.
44 13 8 Give me all active compounds on a given target with the relevant assay data
46 13 8Give me the compound(s) which hit most specifically the multiple targets in a given pathway (disease)
59 14 8 Identify all known protein-protein interaction inhibitors
Clinical data standards in the Semantic WebExample: 14 RDF triples describing one variable (“AEACN”)

RDF triples describing one variable/data elementand also linked to related standard parts
• CDISC2RDF started Oct 2012 as a pre-competitive project with AZ, Roche, W3C et al. to show case Semantic Web standards and Linked Data principles.
• FDA meeting Nov 2012: Solutions for Study Data Exchange Standards Meeting – W3C Semantic Web presentation
• June 2013 the Semantic Technology project, a FDA/PhUSE working group for Emerging Technologies, with 25+ repr. from FDA, CDISC, Pharma:s, CRO:s and software vendors.
• Oct 2013 press release: Representing existing standards (SDTM, CDASH,SEND, ADaM) in RDF.

“We need to build a linked data architecture enabling us to ask questions and solve business problems across a heterogeneous information landscape extending beyond the traditional boundaries of the enterprise.”
