Cell lines | Pancreatic cancer (PC) cells |
Preparation method | Limited solubility. 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 | ~24 h |
Applications | UMI-77 inhibits growth of PC cells, especially for the BxPC-3 and Panc-1 cell line with highest potency. In Panc-1 cells, UMI-77 also effectively induces apoptosis in a time-dependent and dose-dependent manner. Moreover, it leads to a dose-dependent release of cytochrome c and Smac from mitochondria. In addition, the growth inhibition and apoptosis effects of UMI-77 is abrogated by knocking down Mcl-1 expression |
Animal models | BxPC-3 xenograft model in SCID mice |
Dosage form | 60 mg/kg i.v. |
Applications | UMI-77 treatment for 5 consecutive days a week for two weeks significantly inhibits the tumor growth by 65% and 56%. UMI-77 also markedly increases the positive apoptotic cells of tumor sections comparing with the control cohorts. |
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 | UMI-77 is a novel small-molecule inhibitor of Mcl-1 with Ki and IC50 values of 0.49 μM and 0.31 μM [1]. Myeloid cell leukemia-1 (Mcl-1) is a member of the prosurvival Bcl-2 family and is a potent anti-apoptotic protein. Mcl-1 acts as an important survival factor in a broad range of human cancers [1]. UMI-77 is a novel small-molecule Mcl-1 inhibitor. In FP-based binding assays, UMI-77 potently and selectively displaced fluorescent labeled BID-BH3 peptide from Mcl-1 protein with Ki value of 0.49μM and bound to the BH3 binding pocket of Mcl-1 protein. UMI-77 bound to A1/Bfl-1, Bcl-w, Bcl-2 and Bcl-xL with Ki values of 5.33, 8.19, 23.83 and 32.99μM. In a pull-down assay, UMI-77 at 10 μM effectively and dose-dependently inhibited the interactions between BL-Noxa and cellular Mcl-1. It was reported that Mcl-1 regulates pro-apoptotic Bax and Bak proteins and preventing their pro-apoptotic activity. UMI-77 dose-dependently inhibited the binding of Mcl-1 to Bax with IC50 value of 1.43μM. In PC cells, UMI-77 inhibited cell growth and induced apoptosis in a time and dose-dependent way [1]. In BxPC-3 xenografted SCID mice model, UMI-77 exhibited robust anti-tumor efficacy with no toxicity. Also, UMI-77 decreased the anti-apoptotic protein survivin, which potently inhibited apoptosis by antagonizing caspase activity [1]. Reference: |
