ChEMBL errata

This is a page to keep track of errata we've found with the ChEMBL database at [1]

• 4. https://www.ebi.ac.uk/chembldb/index.php/compound/inspect/CHEMBL389012 

Annotated as an Antagonist in ChEMBL, but abstract claims it is an agonist

• 5. CHEMBL293146 is 0 nM for O42392 according to assay CHEMBL818834

In fact, it is 10^-12 M in the paper (or seems to me to be so. 10^-12 is small, but it is not the same as zero.

There are hundreds of these. examples. I will email them to you

• 6. Compound CHEMBL1288160 is annotated at -4000 nM for O96013

and Compound CHEMBL1095696 is annotated at -14 nM for P25099

There are hundreds of a couple of dozen of "negative IC50" values, below:
