Cell lines | BxPC-3 and Colo-357 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 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. |
Reaction Conditions | 750 nM, 72 hours for cell growth inhibition 500 nM, 48 hours for apoptosis induction (measured by Annexin V) |
Applications | The cell viability was assessed by the clonogenic assay. TW-37 resulted in a significant inhibition of colony formation of BxPC-3 and Colo-357 cells when compared with control. Besides that, TW-37 induced apoptosis in a dose- and time-dependent manner. In the Annexin V assay, the percentage of apoptotic cells increased from 5% to 6% in the control to 12% to 14% in both BxPC-3 and Colo-357 cell lines. |
Animal models | Female ICR-SCID mice bearing Colo-357 xenografts |
Dosage form | Intravenous injection, 20 mg/kg/d |
Applications | TW-37 treatment significantly inhibited pancreatic tumor growth in vivo. Western blot analysis showed that the expression level of Notch-1 was significantly lower in tumors from the TW-37–treated mice than those from vehicle-treated control mice. In addition, the expression of Jagged-1 and Notch-1 downstream target gene, Hes-1, was also down-regulated in TW-37–treated tumors. |
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. |
| 产品描述 | TW-37 is a potent small-molecule inhibitor of BCL-2 (Ki= 290 nmol/L), which attenuates BCL-2 activation and inhibits multiple BCL-2 family members including BCL-XL (Ki= 1,110 nmol/L) and MCL-1 (Ki= 260 nmol/L). It binds to the BCL-2 homology domain 3 (BH3) groove of BCL-2 preventing the heterodimerization of proapoptotic proteins (such as Bid, Bim, and Bad) with BCL-2 and subsequently allowing them to induce apoptosis. Recent studies indicate TW-37 is able to inhibit the growth of a broad range of cancer cells (such as breast, prostate, lymphoma, and pancreatic cancer), since it induces S-phase cell cycle arrest with regulation of several important cell cycle related genes, includingp27, p57, E2F-1, cdc25A, CDK4, cyclin A, cyclin D1 and cyclin E.
