STF-62247 Chemical Structure

CAS No. 315702-99-9

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).

Biological Activity

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

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. [1] 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 . [2] 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. [3]

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. [1]


Cell Research:


- Collapse
  • Cell lines: SN12C and RCC4
  • Concentrations: 0 to 40 μM
  • Incubation Time: 24 hours
  • Method:

    For cell viability, 100,000 cells are plated in a 12-well plate. The following day, 1.25 μM STF-62247 is added in the presence or absence of 1 mM 3-MA for 24 hours at 37 °C. Cells are trypsinized and counted by trypan blue exclusion. For XTT assays, 5000 RCC4 with and without VHL cells or 2,500 SN12C with and without VHL shRNA cells are plated in 96-well plates. The following day, vehicle (DMSO), STF-62247 is added to media by serial dilution. Four days later, the media is aspirated and XTT solution containing 0.3 mg/ml of XTT in Phenol Red-free media, 20% FCS and 2.65 mg/ml N-methyl dibenzopyrazine methyl sulfate (PMS) is added to the cells and incubated at 37 °C for 1-2 hours. Metabolism of XTT is quantified by measuring the absorbance at 450 nm on a plate reader.

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.
