YM155
Sepantronium bromide, also known as YM155, is a novel small-molecule suppressant of surviving, the smallest member of inhibitor of apoptosis (IAP) gene family. It exhibits a potent suppressive activity against survivin but has little effect on expression levels of other IAP family members or B-cell lymphoma 2 (BCL-2) related proteins. YM155 also suppresses proliferation in a broad range of human cancer cell lines, induces tumor regression in non-small cell lung cancer (NSCLC), melanoma, bladder, aggressive non-Hodgkin lymphoma, and breast cancer xenograft models, reduces spontaneous metastases, and significantly prolongs the survival of animal harboring established metastatic tumors derived from a human triple-negative breast cancer (TNBC) cell lines.

| General tips | We do not recommend long-term storage for the solution, please use it up soon. |
| Cell experiment: [1] | |
|
Cell lines |
PC-3 and PPC-1 cells |
|
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
1 μM, 48 hours |
|
Applications |
In both cell lines, YM155, at concentrations from 10 to 1000 nM, significantly decreased the viability of cells in a dose-dependent manner. When exposed to YM155, PC-3 and PPC-1 showed a concomitant increase in caspase-3 activity. These results suggest that YM155 induces apoptosis in human HRPC cells. |
| Animal experiment: [1] | |
|
Animal models |
BALB/c nu/nu mice injected with PC-3 cells |
|
Dosage form |
Subcutaneous injection, 10 mg/kg |
|
Applications |
Mice with large established s.c. xenografted PC-3 tumors received a 3-day continuous infusion of YM155 at 10 mg/kg. Saline control animals showed rapid tumor growth from day 0 (366 mm3) to day 7 (1,123 mm3), with no change in intratumoral surviving and actin protein levels. In contrast, animals treated with YM155 showed tumor regression from day 0 (292 mm3) to day7 (162 mm3), and a clear decrease in intratumoral survivin levels on days 3 and 7 was observed. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
