RESUMO
Caspase-3 belonging to a family of cysteine proteases is main executioner of apoptotic cascade pathway. The inhibitors of this protein are useful in the treatment of cardiomyopathy and neurodegenerative diseases. For the discovery of novel Caspase-3 non-peptide inhibitors from Maybridge database, ligand based and structure based virtual screening methods were used. Quantitative 3D pharmacophore models were generated using 25 known inhibitors of Caspase-3 and it was used as initial screen to retrieve the hits from the database. These compounds with high estimated activity were analyzed for drug like properties and docking studies were performed, to study the interaction between new hits and active site. One of the hits (AW01208), with good predictions was selected for synthesis and biological screening. This compound showed an inhibition activity against Caspase-3 in SKNH cell lines.
