Small-Molecule Standardization(In Reality)
Stereochemical information is not
always correct in submitted
structures.
Are the SMILES incorrect or are
these all different compounds with
incorrect names?

Small-Molecule Standardization(In Reality)
Centers often omit alkene geometry.
Do we link all data together under one LSM
ID?

Small-Molecule Standardization(In Reality)
Salt stripping components

complexes
Maps to Pubchem CID
Assigned LSM-ID
Error propagates…

In Conclusion…
• The LINCS data portal (LDP) is really cool!
(and a great resource for industry and academics)
• Compound standardization pipeline is constantly evolving
• Currently, we are implementing a Substructure Search
using Marvin sketch (See life.ccs.miami.edu)
