Cell cycle regulation and anticancer drug discovery

Area of Science:

• Molecular Biology
• Oncology
• Pharmacology

Background:

• Cellular growth, development, and differentiation are regulated by the cell cycle.
• The cell cycle is controlled by cyclin-dependent kinase (CDK)-cyclin complexes, checkpoint kinases, and CDK inhibitors.
• Cell cycle deregulation is a key factor in cancer development.

Purpose of the Study:

• To review the mechanisms of cell cycle regulation.
• To present small-molecule anticancer drugs targeting the cell cycle.
• To outline CDK inhibitors in preclinical and clinical trials for cancer treatment.

Main Methods:

• Literature review of cell cycle regulation mechanisms.
• Identification and summary of small-molecule CDK inhibitors.
• Analysis of CDK inhibitors in preclinical and clinical cancer trials.

Main Results:

• Cell cycle inhibitors are promising therapeutic agents for cancer.
• Both pan-CDK inhibitors and CDK4/6-selective inhibitors are under development.
• Several CDK inhibitors show promise in targeting cell cycle abnormalities in various cancers.

Conclusions:

• Targeting the cell cycle offers a viable strategy for cancer therapy.
• CDK inhibitors represent a significant class of emerging anticancer drugs.
• Further clinical investigation of CDK inhibitors is warranted for diverse cancer types.
