Abstract:
Polo-like kinases (PLKs) play important roles in regulating multiple aspects of cell cycle and cell proliferation. In many cancer types, PLK family members are often dysregulated, which can lead to uncontrolled cell proliferation and aberrant cell division and has been shown to associate with poor prognosis of cancers. The key roles of PLK kinases in cancers lead to an enhanced interest in them as promising targets for anticancer drug development. In consideration of PLK inhibitors and some other anticancer agents, such as BRD4, EEF2K and Aurora inhibitors, exert synergy effects in cancer cells, dual-targeting of PLK and other cancer-related targets is regarded as an rational and potent strategy to enhance the effectiveness of single-targeting therapy for cancer treatment. This review introduces the PLK family members at first and then focuses on the recent advances of single-target PLK inhibitors and summarizes the corresponding SARs of them. Moreover, we discuss the synergisms between PLK and other anti-tumor targets, and sum up the current dual-target agents based on them.
Insights
Polo-like kinases (PLKs) are crucial in cell division and cancer. Targeting PLKs, especially in combination with other agents, offers a potent strategy for enhanced cancer therapy and improved patient prognosis.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Polo-like kinases (PLKs) are vital regulators of cell cycle and proliferation.
- Dysregulation of PLKs is implicated in various cancers, correlating with poor prognosis.
- PLKs represent promising targets for novel anticancer drug development.
Purpose of the Study:
- To review PLK family members and their roles in cancer.
- To summarize recent advances in single-target PLK inhibitors and their structure-activity relationships (SARs).
- To explore synergistic effects of dual-targeting strategies involving PLKs and other anti-cancer targets.
Main Methods:
- Literature review of PLK inhibitors and dual-targeting agents.
- Analysis of structure-activity relationships for PLK inhibitors.
- Discussion of synergistic interactions between PLK inhibitors and other anticancer agents.
Main Results:
- PLK inhibitors show promise as single-target anticancer agents.
- Synergistic effects observed between PLK inhibitors and agents targeting BRD4, EEF2K, and Aurora kinases.
- Emerging dual-target agents combining PLK inhibition with other mechanisms.
Conclusions:
- Dual-targeting strategies involving PLKs offer enhanced efficacy over single-target therapies.
- Further development of dual-target agents holds significant potential for improving cancer treatment outcomes.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
