Pyrazole derivatives, as a class of
heterocyclic compounds, possess unique chemical structures that confer them with a broad spectrum of pharmacological activities. They have been extensively explored for designing potent and selective
anticancer agents. In recent years, numerous
pyrazole derivatives have been synthesized and evaluated for their anticancer potential against various
cancer cell lines. Structure-activity relationship studies have shown that appropriate substitution on different positions of the
pyrazole ring can significantly enhance anticancer efficacy and
tumor selectivity. It is noteworthy that many
pyrazole derivatives have demonstrated multiple mechanisms of anticancer action by interacting with various targets including
tubulin, EGFR, CDK, BTK, and
DNA. Therefore, this review summarizes the current understanding on the structural features of
pyrazole derivatives and their structure-activity relationships with different targets, aiming to facilitate the development of potential
pyrazole-based anticancer drugs. We focus on the latest research advances in anticancer activities of
pyrazole compounds reported from 2018 to present.
