Abstract: Pharmacological targeting cancer stem cells are emerging as a novel therapeutic modality for cancer treatment and prevention. Human cytochrome P450 enzyme CYP4Z1 represents a promising target for its potential role in attenuating the stemness of breast cancer cells. In order to develop potent and selective CYP4Z1 inhibitors, a series of novel N-hydroxyphenylformamidines were rationally designed and synthesized from a pan-CYP inhibitor HET0016. CYP4Z1 inhibitory activities of the newly synthesized derivatives were evaluated, and the structure-activity relationships (SARs) were summarized. Among them, compound 7c exhibited the best inhibitory activity with an IC50 value of 41.8 nM. Furthermore, it was found that 7c decreased the expression of stemness markers, spheroid formation, and metastatic ability as well as tumor-initiation capability in a concentration-dependent manner in vitro and in vivo. Altogether, compound 7c might be a potential lead compound to develop CYP4Z1 inhibitor with more favorable druggability for clinical application to treat breast cancer.
