Small-molecule inhibitors of the cell cycle.

The cell cycle remains an attractive target for the development of small-molecule inhibitors for use as both novel chemotherapeutics and research probes. Given the importance of cytoskeletal dynamics and cyclin-dependent kinases for cell-cycle progression, much interest has focused on the identification of anti-mitotic agents and kinase inhibitors. However recent advances in cell-based screening technologies and an increased interest in inhibitors with greater specificity are beginning to influence the search for novel cell-cycle inhibitors.
