Approach for
analysis
“Let me compare
MW, logP and PSA
for known
oxidoreductase
inhibitors”
“What is the
interaction profile of
known p38 inhibitors?”
“Find me compounds
that inhibit targets in
NFkB pathway assayed
in only functional assays
with a potency <1 μM”

API Overview: Documentation
https://dev.openphacts.org/docs/1.3
The Linked Data API – Simple Rest-ful API
Advantages of the linked data approach while providing a more
familiar API
Lowers the barrier to data access
Based on community standards
REST
JSON, XML, TSV
Not just data access, but complex queries allowing filtering,
pagination, export, etc.
Response template legend for API calls results
1.3 API calls: Concept types
Multiple result formats
Many filtering options per call
Calls that provide filtering parameters
API Entry Points: URLs
https://dev.openphacts.org/docs/1.3
What’s needed to get started?
The API is URL centric
- http://rdf.chemspider.com/906
- http://www.conceptwiki.org/concept/60915889-bbea-4c10a810-7dfd6eb05168
Why?
- Ensures precise identification of the concept
- Allows for dereferencablity
- supports many URLs from different domains
Next: Getting a URL
Finding an initial URL
Compound example: Naphthalene
Textual name:
Naphthalene
SMILES:
C1=CC=C2C=CC=CC2=C1
InChI:
InChI=1S/C10H8/c1-2-6-10-8-4-3-7-9(10)5-1/h1-8H
