THZ2 is a potent and selective CDK7 inhibitor (IC50=13.9 nM).
Cyclin-dependent kinase (CDK) is a group of serine/threonine kinases. It is activated by binding to cyclin and participates in the regulation of cell cycle.
THZ2 selectively targets CDK7 and potently blocks the proliferation of triple-negative breast cancer (TNBC) cells and induces apoptotic cell death without causing alteration in cell cycle. The low nanomolar dose of THZ2 also inhibits the clonogenic growth of TNBC cells with IC50 of 10 nM.
THZ2 is well tolerant in mice as 10 mg/kg intraperitoneal treatment of THZ2 twice daily does not cause weight loss or behavioral changes. THZ2 treatment also significantly reduces the tumor growth rate mice. In addition, both acute (50 hr) or chronic (25 days) exposure to THZ markedly decreases CTD phosphorylation of RNAPII at all three phosphorylation sites as indication of CDk7 being efficiently targeted.

| Cell experiment [1]: | |
|
Cell lines |
TNBC cells |
|
Preparation method |
The solubility of this compound in DMSO is > 28.3 mg/mL. 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. |
|
Reacting condition |
0.1 ~ 10000 nM; 7 days |
|
Applications |
At low nanomolar doses, THZ2 efficiently suppressed the cell growth of TNBC cells (IC50 = ~ 10 nM). Besides, THZ2 also induced apoptotic cell death in triple-negative, but not ER/PR+, breast cancer cells or normal human cells. Meanwhile, THZ2 did not elicit an obvious alteration in cell cycle. |
| Animal experiment [2]: | |
|
Animal models |
Nude mice bearing triple-negative breast tumors |
|
Dosage form |
10 mg/kg; i.p.; 50 hrs or 25 days |
|
Applications |
In nude mice bearing triple-negative breast tumors, THZ2 significantly reduced the growth rate of tumors without affecting body weight. Moreover, both acute (50 hrs) and chronic exposure (25 days) to THZ2 substantially reduced CTD phosphorylation of RNAPII at all 3 phosphorylation sites (i.e. S2, S5 and S7), which indicated that CDK7 was efficiently inhibited in the tumor cells. According to the immunostaining analysis results of tumor tissues isolated from mice treated with THZ2, reduced proliferation and increased apoptosis were 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. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
