Anti-colorectal Cancer Activity of Quinazoline Derivatives: A Comprehensive Review

Abstract

Introduction and Objective: The identification of a bioactive template (or lead) is one of the important features of modern drug discovery. Natural products, synthetic and biotechnological sources, serve as important templates for the development of novel bioactive molecules. Quinazoline is one of the heterocyclic templates present in many natural and synthetic drugs and exhibits various biological activities, including anticancer, by blocking the pharmacological pathway of different targets. Methodology: In this study, the data was collected from the literature and patents to examine the anticolorectal cancer efficacy of quinazoline compounds and their mechanism of actions. According to the published literature and patents, the benzene and/or pyrimidine rings of the quinazoline have been substituted with amino groups or substituted amino groups to develop novel analogues endowed with anticancer properties. The anti-colorectal cancer activity of quinazolines was due to the flexible chain containing terminal phenyl and/or heterocyclic rings (thiazole, pyrazole, piperidine, piperazine, etc.). Results: These quinazoline derivatives were found to inhibit the growth of colorectal cancer cells by modulating the expression of specific genes and proteins involved in cancer progression, such as receptor tyrosine kinases, epidermal growth factor receptors, dihydrofolate reductase, topoisomerases, histone deacetylase, and apoptotic proteins. Conclusion: These findings suggest that the quinazoline nucleus may be exploited to identify new anticolorectal cancer agents with suitable pharmacokinetic profiles.
