1. Cell Cycle/DNA Damage Metabolic Enzyme/Protease Apoptosis
  2. HSP Apoptosis
  3. NCT-58

NCT-58 is a potent inhibitor of C-terminal HSP90. NCT-58 does not induce the heat shock response (HSR) due to its targeting of the C-terminal region and elicits anti-tumor activity via the simultaneous downregulation of HER family members as well as inhibition of Akt phosphorylation. NCT-58 kills Trastuzumab-resistant breast cancer stem-like cells. NCT-58 induces apoptosis in HER2-positive breast cancer cells.

Apoptosis

 

In Vitro

NCT-58 treatment (0.1-20?μM;?72 hours) dose-dependently reduces cell viability in HER2-positive BT474 and SKBR3 cells[1].
NCT-58 treatment (0.1-10?μM;?72 hours) increases the number of early and late apoptotic cells in HER2-positive BT474 and SKBR3 cells[1].
NCT-58 treatment (2-10?μM;?72 hours) effectively reduced the levels of truncated p95HER2 and its phosphorylated form, as well as downregulation of Akt and phospho-Akt (Ser473) protein contents in JIMT-1 and MDA-MB-453 cells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
