ClpP Targeted Library

Mitochondrial Proteases Targeted Libraries Caseinolytic protease (ClpP) found in the human mitochondria is a major member of mitochondrial protein quality control system. This serine protease removes damaged or misfolded proteins in mitochondrial matrix. It is overexpressed in a wide range of acute myeloid leukemia (AML) cases and not in normal hematopoietic precursors [1].

Inhibition of the ClpP is a therapeutic strategy for human acute myeloid leukemia. We have developed ClpP Targeted Library (825 compounds in total). It is a special screening collection containing drug-like compounds with predicted inhibiting activity against ATP-dependent Clp protease proteolytic subunit. The library has been carefully designed with combined of two receptor-based approaches – pharmacophore screening and molecular docking. The four-point pharmacophore model with excluded volumes (on hydrogen atoms of the amino acid residues of the active center) was based on crystal of ClpP with N-formyl methionine (PDB ID: 1TG6) [2]. Top-scored compounds resulted from pharmacophore screening further were docked in the same crystal. Final selection of compounds has been made with docking score cut-off filtering, inspection of intermolecular hydrogen bonds and hydrophobic contacts with key active sites residues, the catalytic triad Ser97, His122 and Asp171 in particular.

This library provides an excellent basis for acute myeloid leukemia drug discovery projects.
