Belzutifan

Catalog No: 20606

CAS Number: 1672668-24-4

Purity: 98% Min.

Belzutifan, also known as PT2977 and MK-6482, is HIF-2alpha inhibitor. PT2977 binds to and blocks the function of HIF-2alpha, thereby preventing HIF-2alpha heterodimerization and its subsequent binding to DNA. This results in decreased transcription and expression of HIF-2alpha downstream target genes, many of which regulate hypoxic signaling. This inhibits cell growth and survival of HIF-2alpha-expressing tumor cells. HIF-2alpha, the alpha subunit for the heterodimeric transcription factor HIF-2, is overexpressed in many cancers and promotes tumorigenesis. Belzutifan was approved in 2021 for treatment of von Hippel-Lindau disease under certain conditions
