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. |

* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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 MSDS / 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 MSDS / 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.
