PAINS: Pan-assay interference compounds
Possible false positive signal mechanisms:
- Form aggregates
- Absorb or emit light at relevant wavelengths (λex = 680 nm or λem = 520-620 nm)
- Trap toxic or reactive metals used to synthesize molecules
- Sequester metal ions that are essential to a protein’s function
- React with singlet oxygen
- Redox cyclers: produce hydrogen peroxide, which inactivates the target
protein and makes the compound look like a good inhibitor
- Are inherently “sticky” and can bind to many sites on proteins
- Alter proteins chemically without fitting specifically into a binding site
- Covalently bind to proteins
