THZ2

SKU: orb1226066

Description

THZ2, an analogue of THZ1 with improved pharmacokinetic features, is a potent, selective CDK7 inhibitor with IC50 of 13.9 nM, displays a 5-fold improved half-life in vivo compared with THZ1; selectively targets CDK7 and potently inhibits the growth of triple-negative but not ER/PR+ breast cancer cells, efficiently suppresses the clonogenic growth of TNBC cells with IC50 of 10 nM; Like THZ1, THZ2 induces apoptotic cell death in triple-negative but not ER/PR+ breast cancer cells or normal human cells; suppresses the growth of triple-negative breast tumors in xenograft models.

Bioactivity

• In Vivo:
  THZ2 (10 mg/Kg) markedly reduces the growth rate of tumors in mice and demonstrates an anti-tumor activity. Compared to vehicle-treated tumors, tumor tissues isolated from mice treated with THZ2 has reduced proliferation and increased apoptosis, as indicated by immunostaining against Ki67 and cleaved Caspase 3 respectively. THZ2 in NOD-SCID mice leads to reduced body weight, suggesting that THZ2 mayt be less well-tolerated in this particular mouse strain.
• In Vitro:
  THZ2 selectively targets CDK7 and potently inhibits the growth of triple-negative but not ER/PR+ breast cancer cells. THZ2 at low nanomolar doses also efficiently suppresses the clonogenic growth of TNBC cells with IC50 of appr 10 nM. THZ2 induces apoptotic cell death in triple-negative but not ER/PR+ breast cancer cells or normal human cells.
