Abstract
Background: Many impediments of current anti-cancer therapies have urged scientists to discover new agents. As a result of growing spectrums of new targets and strategies and recent biological and biotechnological progresses, many anti-cancer agents such as monoclonal antibodies, small molecule tyrosine kinase inhibitors and epigenetic drugs have been reached to clinical trials.
Objectives: This review helps to understand the rationale for the development of inhibitors against major targets such as cell growth, proliferation, survival, angiogenesis and recent targets such as proteasome, heat shock proteins, and epigenetics.
Methods: Recent approaches of the target-based anti-cancer drug developments were highlighted to giving some examples from approved agents. Many factors, such as metabolic change, hypoxia, cancer precursors and cancer resistant cells, and their effect on drug resistance mechanisms were discussed. The impacts of advanced computational techniques to identify targets of cancer and designing more selective inhibitors were explained.
Results: Contributions of recent techniques such as a network analysis, the precise modes of action and computational methodologies especially simulation of bio-molecular processes to clarify targets, mechanism actions and reasons of lack of efficacy of anti-cancer drugs have been explained. The relationship between the several mechanisms and molecular design strategies has been discussed.
Conclusion: This review provides an overview of important targets and design strategies of anti-cancer drugs, advantages and disadvantages of these methods and evaluation of some currently used anticancer targets in clinical studies.
Keywords: Cancer, epigenetic, kinases, angiogenesis, anticancer agents, major targets.
