HIF-1/2α-IN-1 (Compound #25) has an IC50 value of 0.92 μM and inhibits HIF-2α activity (0.01-100 μM) [1]. At higher concentrations, HIF-1α is inhibited by blocking the function of iron-sulfur cluster assembly, while HIF-1/2α-IN-1 (0-10 μM, 24 h) reduces HIF-2α by blocking IRE-dependent translation. Second Mediator (ISCA2) [1]. Iron starvation response is triggered by HIF-1/2α-IN-1 (1 μM, 24 hours) targeting ISCA2 [1]. The viability of 786-0 and RCC4 cells is decreased by HIF-1/2α-IN-1 (0-100 μM, 24 hours) (IC50=1.7 μM (786-0), 10.6 μM (786-0 VHL) and IC50=4.8 μM (RCC4), 71.0 μM (RCC4 VHL)) [1].

Cell Assay |
Cell Viability Assay [1]
Cell Types: 786-0 cells and RCC4 cells Tested Concentrations: 0.01-100 μM Incubation Duration: 24 hrs (hours) Experimental Results: The cell viability of 786-0 cells and RCC4 cells was diminished. Western Blot Analysis[1] Cell Types: 786-0 cells and RCC10 cells Tested Concentrations: 0, 0.5, 1, 2.5, 10 μM Incubation Duration: 24 hrs (hours) Experimental Results: diminished HIF-2α activity and protein levels. Higher concentrations or treatment durations reduce HIF-1α levels but do not promote proteasomal degradation of HIF-1/2α. Inhibits HIF-2α IRE (IRE-Luc)-driven luciferase production. IRP2 and TFRC increased in a dose-dependent manner, while FTH diminished. RT-PCR[1] Cell Types: 786-0 Cell Tested Concentrations: 0, 0.5, 1, 5 μM Incubation Duration: 24 hrs (hours) Experimental Results: Caused a dose-dependent decrease in the transcription of HIF-2α target genes VEGFA and POU5F1, but did not inhibit it HIF-2α transcription. |
Animal Protocol |
Animal/Disease Models: NRG or balb/c (Bagg ALBino) mouse [1] (6-8 weeks old, male, 10 mice per group)
Doses: 30, 60 mg/kg Doses: po (po (oral gavage)) daily Experimental Results: Dramatically inhibited tumor growth . It was well tolerated with no significant weight loss. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

5 mM | 0.5430 mL | 2.7148 mL | 5.4296 mL | |
10 mM | 0.2715 mL | 1.3574 mL | 2.7148 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
