Biological Activity
| ln Vitro | KC7F2 (0-80 μM; 6 hours) potently reduces HIF-1α protein levels in a dose-dependent manner under hypoxic conditions; HIF-1α levels were significantly reduced at a concentration of 20 μM [Conditions [1]. KC7F2 (15-25 μM; 0-72 hours) exhibits clear dose-responsive cytotoxicity with IC50 values of approximately 15-25 μM, depending on the cell line, and this effect is more severe under hypoxic conditions. The rate at which HIF-1α protein regulation occurs is unaffected by KC7F2 [1]. While HIF-1α mRNA regulation is not inhibited by KC7F2, its protein production is [1]. The eukaryotic initiation regulator 4E-binding protein 1 (4EBP1) is regulated by KC7F2 [1]. Cell |

Solubility Data
| Solubility (In Vitro) | DMSO : ≥ 32 mg/mL (~56.10 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (4.38 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.38 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
