  4. Chrysotoxine

Chrysotoxine is a dual inhibitor of Src/Akt. Chrysotoxine suppresses cancer stem cells (CSCs) phenotypes by down-regulating Src/Akt signaling. Chrysotoxine reduces cell viability and increases apoptosis level in H460 and H23 cells instead of non-tumor cell lines. Chrysotoxine shows rapid excretion and low bioavailability in rats. Chrysotoxine is used in cancer research.

Description

Chrysotoxine is a dual inhibitor of Src/Akt. Chrysotoxine suppresses cancer stem cells (CSCs) phenotypes by down-regulating Src/Akt signaling. Chrysotoxine reduces cell viability and increases apoptosis level in H460 and H23 cells instead of non-tumor cell lines. Chrysotoxine shows rapid excretion and low bioavailability in rats. Chrysotoxine is used in cancer research[1][2].

In Vitro

Chrysotoxine (50 nM, 24 h) reduces cell viability and increases apoptosis level in H460 and H23 cells[1].
Chrysotoxine (5-20 nM, 72 h) suppresses the CSC populations in H460 and H23 cells[1].
Chrysotoxine (0-20 nM, overnight) decreases the stemness of H460 and H23 cells by suppressing the Src-Akt activating mechanism[1].

Western Blot Analysis[1]

Cell Line: 460, H23 cells
Concentration: 0-20 µM
Incubation Time: Overnight
Result: Significant decreased the p-Src and p-Akt expression in a dose-dependent manner instead of Src and Akt.
Significantly reduced the down-stream stem cell transcription factor Sox2 as the decline of p-Src in H460 and H23 cells.

Cell Viability Assay[1]

Cell Line: 460, H23 cells
Concentration: 0, 1, 5, 10, 20 and 50 µM

Result: Significantly reduced cell viability and increased H460 and H23 cells cell apoptosis at 50 µM with IC50s of 127.34 and 145.47 µM, respectively.
Showed no cytotoxic effect on non-tumor cell lines at all tested concentrations.

Cell Differentiation Assay[1]

Cell Line: 460, H23 cells
Concentration: 5-20 µM

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.
