Abstract: Targeting the tumor microenvironment is a promising strategy to prevent metastasis,
overcome acquired drug resistance, and improve the therapeutic effect. Hypoxia
is one of the characteristics of the tumor microenvironment, which is mainly regulated by
hypoxia-inducible factors. Hypoxia-inducible factors (HIFs) including HIF-1α, HIF-2α,
and HIF-3α, of which HIF-2α has assumed a more important role in tumor hypoxia environment.
It has been demonstrated that HIF-2α plays an important role in tumor diseases,
including renal cell carcinoma, breast cancer, non-small cell lung cancer, and gastric cancer,
among others. Therefore, targeting HIF-2α has become one of the important strategies
for treating cancers. HIF-2α inhibitors can be divided into two categories: specific inhibitors
and non-specific inhibitors. The former includes synthetic monomer compounds
and traditional Chinese medicine extracts. In this review, we summarized, classified, and
discussed current research on the structure, structure-activity relationship (SAR), and
pharmacology of HIF-2α inhibitors, which is helpful to the rational design of effective
drugs for various types of malignant tumors.
