生物活性

FLT3/HDAC-IN-3 is a dual inhibitor of FLT3 and HDAC. FLT3/HDAC-IN-3 potently inhibits FLT3 (IC50 = 14 nM), HDAC1 (IC50 = 27 nM), HDAC6 (IC50 = 20 nM), and FLT3D853Y (IC50 = 55 nM), exhibits weak activity against HDAC8, and shows no activity against HDAC4. FLT3/HDAC-IN-3 possesses kinase selectivity, plasma stability, and stability in human liver microsomes. FLT3/HDAC-IN-3 demonstrates anti-proliferative effects in a variety of hematological malignancy cell lines. FLT3/HDAC-IN-3 shows efficacy in the Jeko-1 xenograft model without observed significant toxicity. FLT3/HDAC-IN-3 can be used in the study of hematological malignancies[1].

Western Blot Analysis[1]

Cell Line: MV-4-11 cells
Concentration: 0 nM, 50 nM, 250 nM, 1000 nM
Incubation Time: 72 h
Result: Dose-dependently inhibited phosphorylated FLT3 and p-STAT5; increased acetylated histone H3 (H3Ac) levels in a concentration-dependent manner, with higher H3Ac accumulation at 250 nM compared to SAHA at the same concentration; upregulated pro-apoptotic protein Bax in a dose-dependent manner.

Cell Cytotoxicity Assay[1]

Cell Line: MV-4-11, Jeko-1 cells
Concentration: 0 nM, 50 nM, 250 nM, 1000 nM
Incubation Time: 72 h
Result: Induced a dose-dependent increase in red fluorescence (dead cells) and decrease in green fluorescence (live cells) in both MV-4-11 and Jeko-1 cells.

Apoptosis Analysis[1]

Cell Line: MV-4-11, Jeko-1 cells
Concentration: 0 nM, 50 nM, 250 nM, 1000 nM
Incubation Time: 48 h or 72 h
Result: Induced apoptosis in a time- and dose-dependent manner; at 72 h, induced 47.7% apoptosis at 250 nM and up to 75% apoptosis at 1000 nM in MV-4-11 cells, with effects comparable to SAHA + Tandutinib combination treatment; also induced dose-dependent apoptosis in Jeko-1 cells.

Cell Cycle Analysis[1]

Cell Line: MV-4-11 cells
Concentration: 0 nM, 50 nM, 250 nM, 1000 nM
Incubation Time: 72 h

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.
