Bioactivity

• In Vivo:
  In nude mice bearing MDA-MB-231 tumors, Cucurbitacin B (1 mg/kg, i.p.) inhibits tumor growth by 55 %, and causes lower serum glucose levels.
• In Vitro:
  Cucurbitacin B inhibits the growth of 5 GBM cell lines: U87, U118, U343, U373 and T98 g by affecting the cytoskeleton and the JNK pathway, with ED50 ranged from 5 nM to 100 nM. Cucurbitacin B also causes cell cycle arrest at the G2/M phase, decreases cell migration and induces apoptosis of GBM cells. In human breast cancer cell lines, Cucurbitacin B also inhibits cell growth with ED50 varied from 30.3 nM to 418 nM, and rapidly induces cytoskeletal disruption. In addition, Cucurbitacin B possesses immunomodulatory and anti-inflammatory effects, depending on the induction of heme oxygenase-1 expression via Nrf2 activation.
