STF-62247 is a molecule targeting VHL-deficient renal cell carcinoma that induces autophagy. STF-62247 shows selective toxicity and growth inhibition of renal cells lacking VHL; 25-fold greater sensitivity observed for cells with VHL deficiency compared to wild-type (VHL+).

Columns depict relative densitometric values that were obtained by comparing with (β-actin. Presenilin 1, Nicastrin, and Pen-2 were increased with the 3-MA treatment (*P<0.001) while the other component of the γ-secretase complex (APH-1 and Presenilin 2) has no difference, compared with the STF-62247 treatment. Moreover, Bace1 and ADAM17 respectively had no difference between 3-MA and STF-62247 treatments. Both autophagy inhibitor and inducer activated α-, β-, and γ-secretases (*P<0.005). Abbreviations: Aβ, beta-amyloid; ADAM17, a disintegrin and metalloprotease 17; APH-1, anterior pharynx-defective 1; APP, amyloid protein precursor; Bace1, beta-site APP cleavage enzyme; 3-MA, 3-methyladenine; Con, control, LC3, microtubule-associated protein 1A/1B-light chain 3.

|Description||STF-62247 is a molecule targeting VHL-deficient renal cell carcinoma that induces autophagy. STF-62247 shows selective toxicity and growth inhibition of renal cells lacking VHL; 25-fold greater sensitivity observed for cells with VHL deficiency compared to wild-type (VHL+).|
In vitro, STF-62247 shows cytotoxicity and tumor growth inhibitory activity against wild-type VHL and VHL-deficient renal cell carcinoma (RCC) in a HIF-independent manner with IC50 of 16 μM and 0.625 μM, respectively. Moreover, STF-62247 also leads to cell death by increasing acidification and inducing autophagy in VHL-deficient cells.  STF-62247 specifically induces macroautophagy and enhances the fusion of autophagosome and lysosomes to form autolysosomes by interfering with Golgi-endoplasmic reticulum transport in cells that have lost VHL .  A recent study shows that induction of autophagy by STF-62247 increases sensitivity of RCC under hypoxic conditions to radiation in a VHL-dependent manner. 
|In vivo||In vivo mouse model, STF-62247 at a dose of 8 mg/kg by intraperitoneal injection significantly reduces tumor growth of VHL-deficient SN12C tumor cells. |
|In vitro||DMSO||53 mg/mL (198.24 mM)|
|Ethanol||3 mg/mL (11.22 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
1% DMSO+30% polyethylene glycol+1% Tween 80
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
