30.0mg/ml Taking the 1 mL working solution as an example, add 30 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Sepantronium Bromide(YM155) is a potent survivin suppressant by inhibiting Survivin promoter activity with IC50 of 0.54 nM in HeLa-SURP-luc and CHO-SV40-luc cells; does not significantly inhibit SV40 promoter activity, but is observed to slightly inhibit the interaction of Survivin with XIAP. YM155 down-regulates survivin and XIAP, modulates autophagy and induces autophagy-dependent DNA damage in breast cancer cells. Phase 2.
Targets
Survivin [1]
(HeLa-SURP-luc, CHO-SV40-luc cells)
0.54 nM
In vitro

YM155 is not sensitive to survivn gene promoter-driven luciferase reporter activity even at 30 μM. YM155 significantly inhibits endogenous survivin expression in PC-3 and PPC-1 human HRPC cells with deficient p53 through transcriptional inhibition of the survivin gene promoter. On the contrary YM155 shows no sufficient effect on protein expression of c-IAP2, XIAP, Bcl-2, Bcl-xL, Bad, α-actin, and β-tubulin at 100 nM. YM155 indicates great apoptosis in human cancer cell lines including PC-3 and PPC-1 with a concomitant increase in caspase-3 activity. YM155 potently inhibits human cancer cell lines (mutated or truncated p53) including PC-3, PPC-1, DU145, TSU-Pr1, 22Rv1, SK-MEL-5 and A375 with IC50 from 2.3 to 11 nM, respectively. [1] YM155 increases the sensitivity of NSCLC cells to γ-radiation. The combination of YM155 and γ-radiation increases both the number of apoptotic cells and the activity of caspase-3. YM155 delays the repair of radiation-induced double-strand breaks in nuclear DNA. [2]
In vivo

YM155 completely inhibits the tumor growth of PC-3 s.c. xenografted prostate tumors at doses of 3 and 10 mg/kg, without body weight loss and blood cell count decrease. Pharmacokinetic analysis shows that YM155 is highly distributed to tumor tissue. Moreover, YM155 shows 80% TGI at a dose of 5 mg/kg in PC-3 orthotopic xenografts. [1] The combination therapy with YM155 and γ-radiation shows great antitumor activity against H460 or Calu6 xenografts in nude mice. [2]

Protocol (from reference)

Kinase Assay:

[1]
  • Promoter-luciferase reporter assay

    A 2,767-bp sequence of human survivin gene promoter is isolated from human genomic DNA by PCR using Pyrobest polymerase and the following primers: 5
Cell Assay:

[1]
  • Cell lines

    Hormone refractory prostate cancer cell lines (PC-3, PPC-1, DU145, TSU-Pr1 and 22Rv1) and malignant melanoma cell lines (SK-MEL-5 and A375)

  • Concentrations

    ~ 100 nM

  • Incubation Time

    48 hours

  • Method

    Cells are seeded in 96-well plates at a density of 5-40 × 103. YM155 is dissolved in DMSO and added to cells for 48 hours. Then the cell count is determined by sulforhodamine B assay.
Animal Study:

[1]
  • Animal Models

    PC-3 s.c. (orthotopic) xenografts in male nude mice (BALB/c nu/nu)

  • Dosages

    5 mg/kg

  • Administration

    Subcutaneous injection as a 3-day continuous infusion per week for 3 weeks by an implanted micro-osmotic pump
