CNS-related Screening Libraries
new
To facilitate CNS-focused drug design research projects, Life Chemicals is offering a special selection of CNS-related Screening Compound Libraries that address acute needs for general CNS-oriented compounds, as well as cover a broad range of CNS drug targets relevant to test models of Parkinson’s disease, Alzheimer’s disease and many other complex neurological disorders.

Covalent Inhibitor Library
updated
The Library comprises over 10,000 covalent modifiers containing specific functional groups (“warheads”), that are known to form covalent bonds with amino acid residues (Lys, Cys, Ser, Asp, Glu, and Tyr) in binding sites of target proteins. The extended Rule of Five criteria were applied for the compound selection. Additional separate focused sets of covalent binders targeting each of the indicated amino acid residues can be provided on request.

Serine Protease Screening Libraries
updated
Serine proteases have been shown to play a multifarious role in various diseases (such as cancer proliferation, auto-immune disorders, allergy). We have designed two dedicated screening compound collections of potential serine proteinase inhibitors for drug discovery projects: the Focused Library by 2D fingerprint similarity and Targeted Library by receptor-based virtual screening for subtilisin-like serine proteases.

Antituberculosis Libraries
updated
4,200 analogs of known M. Tuberculosis inhibitors, selected by 2D fingerprint similarity search employing organism- and single protein-type bioactivity records from ChemBL, were included in the Antituberculosis Focused Library. Antituberculosis Docking Library, designed with a receptor-based approach, comprises over 3,400 screening compounds, potential inhibitors of the InhA enzyme, singled out by molecular docking.
