Pharmacology
Belzutifan is a hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor that binds to HIF-2α and blocks its interaction with HIF-1β, leading to reduced transcription of HIF-2α target genes associated with cellular proliferation, angiogenesis, and tumor growth.
Everolimus is an mTOR inhibitor that binds the intracellular protein FKBP-12 to form an inhibitory complex with mTORC1, suppressing downstream effectors (S6K1, 4E-BP1) involved in protein synthesis, cell proliferation, and angiogenesis, and reducing HIF-1 and VEGF expression; mTOR pathway dysregulation occurs in several human cancers and in tuberous sclerosis complex.
