生物活性

TAK-659 is a highly potent, selective, reversible and orally available dual inhibitor of spleen tyrosine kinase (SYK) and fms related tyrosine kinase 3 (FLT3), with an IC50 of 3.2 nM and 4.6 nM for SYK and FLT3, respectively. TAK-659 induces cell death in tumor cells but not in nontumor cells, and with potential for the treatment of chronic lymphocytic leukemia (CLL)[1][2][3][4].

IC50 & Target

IC50: 3.2 nM (Syk), 4.6 nM (FLT3)[1]

体外研究
(In Vitro)

TAK-659 inhibits cellular proliferation in SYK-dependent DLBCL and FLT3-dependent AML cell lines[1][3].
TAK-659 (5 μM; 1-24 hours) induces Casp3 activation in the LMP2A/MYC cells which was readily apparent at 4 h and reached maximum levels at 8 h of treatment[4].
TAK-659 (0.01-10 μM; 1 hour) stimulates expression of phospho-Syk at Tyr525 and Tyr352 and phospho-ERK1/2 increased in Ramos cells[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Apoptosis Analysis[4]

Cell Line: LMP2A/MYC cells
Concentration: 5 µM
Incubation Time: 1 hour, 2 hours, 4 hours, 8 hours, 24 hours
Result: Induced apoptosis in LMP2A/MYC lymphoma cells.

Western Blot Analysis[2]

Cell Line: Ramos cells
Concentration: 0.01 μM,0.1 μM,1 μM,10 μM
Incubation Time: 1 hour
Result: Enhanced expression of phospho-Syk at Tyr525 and Tyr352 and phospho-ERK1/2 in stimulated Ramos cells.
体内研究
(In Vivo)

TAK-659 (100 mg/kg/day; p.o.; for 10 days) treatment totally abrogates splenomegaly and tumor development in LMP2A/MYC mice in both pretumor and tumor cell transfer experiments[4].
TAK-659 treatment kills tumor cells, but not host cells within the spleen and tumors[4].
TAK-659 treatment abrogates metastasis of tumor cells into bone marrow[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: LMP2A/MYC double transgenic mice[4]
Dosage: 100 mg/kg/day
Administration: Oral gavage; for 10 days
Result: Inhibited LMP2A-induced tumor cell survival in vivo.

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.
