Abstract

Abnormalities in the normal regulation of the cell cycle are a hallmark of neoplasia. Drugs directed against the cyclin-dependent kinases (CDKs), which govern the normal orderly progression through the cell cycle, have been proposed to address the pathogenic defect in tumors. Recently, CDK family members that do not regulate the cell cycle directly but instead influence transcription (CDK7, CDK8, and CDK9) and neuronal and secretory cell function (CDK5) have been described. Continued synthetic chemistry efforts have defined important new selective inhibitors of CDKs, and strategies directed at newly described CDK-related targets, such as transcription control, can now be envisaged. CDKs remain important and novel targets whose potential needs to be more fully explored, albeit in light of the newly emerging complexities of their cellular physiology.
