Small molecule
and RNAi
Three connected databases
… A public resource providing chemical structures and
comprehensive information on the biological activities of small
molecules and other reagents including RNAi
PubChem goals
• a public repository for molecular structures
and bioassay data
• integrate information from various sources
to provide value added annotation
• develop data search, analysis, and retrieval
tools to facilitate the use of chemical
structures and bioactivity results

PubChem history: the MLI initiative
(http://mli.nih.gov/mli/ 2004-2014)
•
•
•
identify and develop small-molecule chemical probes through highthroughput screening (HTS)
expand the use of chemical probes for basic research (e.g.
understanding the unknown biological systems, rare diseases)
all data must be deposited into PubChem to be public
