Description: PT2385 is an orally active, small molecule inhibitor of hypoxia inducible factor (HIF)-2alpha, with potential antineoplastic activity. Upon oral administration, HIF-2alpha inhibitor PT2385 allosterically binds to 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 tumor cell growth and survival.

More Info:

Biological target: PT2385 is a selective HIF-2α antagonist with luciferase EC50 of 27 nM and no significant off-target activity.
In vitro activity: This study investigated the benefits of using PT2385 to treat severe placental dysfunction. In vitro, RNA sequencing analysis and conventional techniques showed that PT2385 treated cytotrophoblast displayed an enhanced differentiation into syncytiotrophoblasts and normalized angiogenic factor secretion compared with vehicle-treated cells. Reference: Hypertension. 2023 May;80(5):1011-1023. https://pubmed.ncbi.nlm.nih.gov/36876500/
In vivo activity: PT2385 specifically targeted HIF2α, a key oncogenic driver in clear cell renal cell carcinoma, by blocking its dimerization with ARNT/HIF1β. This inhibition led to the suppression of HIF2α-dependent genes in tumor cells and resulted in dramatic tumor regressions when administered to tumor-bearing mice. PT2385 did not affect cardiovascular performance. Reference: Cancer Res. 2016 Sep 15;76(18):5491-500. https://pubmed.ncbi.nlm.nih.gov/27635045/
