Elesclomol (STA-4783)
Elesclomol (also known as STA-4783), originally identified in a cell-based phenotypic screen for proapoptotic activity, is a novel small-molecule that potently induces apoptosis of cancer cells through the rapid generation of reactive oxygen species (ROS) and the induction of unmanageable levels of oxidative stress. Elesclomol exhibits autitumor activity against a broad spectrum of types of cancer cell in human tumor xengograft models due to its excessive ROS production and elevated levels of oxidative stress leading to the death of cancer cells. Elesclomol is currently being studies as a novel cancer therapeutic, in which it has demonstrated ability to prolong progression-free survival in study subjects.

| Cell experiment [1]: | |
|
Cell lines |
HSB2 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 |
200 nM; 18 hrs |
|
Applications |
In HSB2 cells, Elesclomol increased the number of early and late apoptotic cells (3.7- and 11-fold, respectively). |
| Animal experiment [2]: | |
|
Animal models |
Nude mouse xenograft models of human breast cancers (MDA435, MCF7 and ZR-75-1), lung cancer (RER) or lymphoma (U937) |
|
Dosage form |
25 ~ 100 mg/kg; i.v. |
|
Applications |
In nude mouse xenograft models of human breast cancers (MDA435, MCF7 and ZR-75-1), lung cancer (RER) or lymphoma (U937), a single dose of Elesclomol (25 ~ 100 mg/kg) showed no antitumor activity. But Elesclomol substantially enhanced the efficacy of chemotherapeutic agents such as Paclitaxel, both in terms of tumor regression and extended survival of mice. |
|
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. |
