The database development started in 2005, it now contains:
Plasma Protein Binding Database
Drugs and toxic substances can be bound to proteins in plasma or blood, which reduces the free (effective) concentration of compounds in vivo. For toxicity evaluations and in drug discovery it is important to know to which extend a compound is bound to plasma proteins (PPB%):
Data records are comprehensively curated and annotated with up to 20 data fields describing the species, exp. conditions & methods (EQ, UF, UC, GF, albumin binding), compound concentration, etc.
Reliable models to forecast plasma protein binding (PPB%) of substances have been created and show a high quality of prediction. We found a low Mean Absolute Error (MAE) and a high correlation between experimental and predicted PPB values based on a large and independent validation dataset.

The project results were presented in January 2020 at the BMBF-Statusseminar in Berlin.
