 0.350mg/ml (1.10mM) Taking the 1 mL working solution as an example, add 50 μL of 7 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml betekent licht oplosbaar of onoplosbaar.
* Houd er rekening mee dat Selleck de oplosbaarheid van alle verbindingen intern test en de werkelijke oplosbaarheid enigszins kan afwijken van gepubliceerde waarden. Dit is normaal en is te wijten aan lichte batch-tot-batch variaties.
* Verzending op kamertemperatuur (Stabiliteitstests tonen aan dat dit product zonder koelmaatregelen kan worden verzonden.)

Biologische activiteit

Beschrijving STF-083010 is een specifieke IRE1α endonuclease-remmer die de kinase-activiteit ervan niet beïnvloedt.
Doelen
IRE1α endonuclease
In vitro In RPMI 8226, MM.1S, and MM.1R MM cell lines, STF-083010 exhibits cytostatic and cytotoxic activity in a dose and time dependent manner. In MiaPaCa2, Panc0403, and SU8686 cell lines, this compound inhibits XBP1 splicing and blocks IRE1α's endonuclease activity without affecting its kinase activity. In Eμ-TCL1 CLL cells, it exhibits about 70% growth inhibition after 3 days culture. In MEC1 and MEC2 cells, this chemical produces 20% growth inhibition in 48 h. WaC3 cells respond to treatments with this compound with gradually decreased growth.
In Vivo In human multiple myeloma (MM) xenografts model, STF-083010 (i.p., 30 mg/kg) significantly inhibits the growth of tumor.

Protocol (uit referentie)

Kinase-assay:[1]
  • Cell-vrije IRE1-assays

    Autofosforylatie-activiteit wordt bepaald door de toevoeging van 32P-γ ATP. Endonuclease-activiteit wordt bepaald door de toevoeging van radiogelabeld HAC1 508-nt RNA-substraat dat in vitro is gesynthetiseerd met behulp van α32P-UTP. STF-083010 wordt geïncubeerd met recombinant hIRE1-eiwit, radiogelabeld HAC1 508 nt RNA en geschikte buffers. Kinase-activiteit wordt gekwantificeerd door middel van polyacrylamidegelelektroforese. RNAse-splitsingsproducten worden gekwantificeerd door 32P-γATP of 32P-UTP autoradiografie.
Celassay:[1]
  • Cellijnen

    Panc0403, Panc1005, BxPc3, and MiaPaCa2 cell lines

  • Concentraties

    ~50 μM

  • Incubatietijd

    ~48 h

  • Methode

    Three thousand cells are seeded in 96-well plates overnight and drug treatment started the next day. After 48 h incubation, MTT is added to cells and cultured at 37℃ for 4 h followed by stop solution (4 mM HCl, 0.1% Nondet P40 in isopropanol) which is added to dissolve MTT. The plates are read with a spectrophotometer at 590 nm absorbance with reference at 630 nm. IC50 values are calculated using GraphPad Prism.
Dierstudie:[1]
  • Dierlijke modellen

    NOD/SCID/IL2Rγ null mice

  • Doseringen

    30 mg/kg

Effect of STF-083010, an inhibitor of IRE, on the degradation of APP induced by geniposide. After primary cortical neurons were pre-incubated with 25 μM STF083010 for 30 min, geniposide (10 μM) and high glucose (75 mM) were added and the cells were incubated for 24 h. The protein level of APP was determined by western blot. Data are shown as mean ± SD from three independent experiments. *p < 0.05, versus control (the group of 25 mM glucose); #p < 0.05 versus the group of 75 mM glucose.; &, p < 0.05 versus the group of high glucose plus geniposide.
