Casdatifan
Based on 1 Customer Validation
Casdatifan (AB521) is an orally active and selective allosteric small-molecule inhibitor of hypoxia-inducible factor 2α (HIF-2α). Casdatifan inhibits pro-tumor gene transcription by blocking the heterodimerization of HIF-2α with ARNT, and significantly suppresses tumor growth in clear cell renal cell carcinoma (ccRCC) models either as a monotherapy or in combination with agents such as Zimberelimab (HY-P99109). Casdatifan is applicable for the research of ccRCC.

Activité biologique
Casdatifan (2-10 μM; 24 h) reduces HIF-2α protein levels in 786-O and A-498 clear cell renal cell carcinoma (ccRCC) cells under normoxic conditions[1].
Casdatifan potently inhibits VEGF secretion in 786-O ccRCC cells, with an IC50 of 28.9 nM[1].
Casdatifan (0.001-10 μM; 21 days) inhibits the anchorage-independent growth of 786-O ccRCC cells in a concentration-dependent manner[1].
Casdatifan (1 μM; 20 h) inhibits HIF-2α-dependent gene transcription in hypoxically induced primary human M2-polarized macrophages[1].
Casdatifan (3 days) reduces HIF-2α protein levels in activated hypoxic primary human CD8+ T cells without impairing T cell proliferation or cytokine secretion[1].

-
Cell Line:786-O and A-498 cells
-
Concentration:2, 10 μM
-
Incubation Time:24 h
-
Result:Caused a marked reduction in HIF-2α protein levels in both 786-O and A-498 cells.
Casdatifan (30 mg/kg; p.o.; once daily; until study endpoint) significantly enhances the antitumor efficacy in the NSG-MHC I/II DKO humanized PBMC A-498 ccRCC xenograft model when administered in combination with Zimberelimab (HY-P99109)[1].

-
Animal Model:NU-Foxn1nu nude mice (female, 6-8 weeks old, subcutaneous xenograft of 786-O or A-498 cells)[1]
-
Dosage:3 mg/kg; 10 mg/kg; 30 mg/kg; 100 mg/kg
-
Administration:p.o.; daily; until the end of the study
-
Result:Significantly reduced tumour burden in both 786-O and A-498 models.
Decreased HIF-2α protein levels and tumour cell proliferation (Ki-67 staining), and downregulated HIF-2α target genes (VEGFA, CCND1, CXCR4) in tumour tissues in a dose-dependent manner.
-
Animal Model:NSG-MHC I/II DKO (female, 4-5 weeks old, humanized PBMC A-498 xenograft model)[1]
-
Dosage:30 mg/kg
-
Administration:p.o.; daily; until the end of the study
-
Result:Led to more rapid and sustained tumour regression than either monotherapy, with 60% of mice achieving a complete response after treatment cessation.
Induced considerable tumour regression but growth resumed after treatment stop until the end of the study, while Zimberelimab alone showed modest efficacy.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.69 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.69 mM); Clear solution
