Molecular Designing of Small-Molecule Inhibitors for Apoptosis Regulation

Part of the Current Human Cell Research and Applications book series (CHCRA)


Apoptosis is a distinctive mode of programmed cell death, which is involved in organ life cycle in multicellular organism. Dysregulation of apoptotic processes has been implicated in a wide variety of diseases, such as cancer, neurodegenerative disorders, and ischemic injury. To date, many kinds of key proteins in apoptotic processes have been identified and targeted for therapeutic strategies. Several effective small molecules have been designed to modulate the key regulatory proteins, such as Bcl-2, XIAP, MDM2, and caspases. This chapter reviews the current development of small-molecule inhibitors targeting apoptosis regulatory proteins, and as an example, our structure-based approaches for the designing of caspase-3-specific inhibitors will be described.
