ITK degrader 1 is a highly selective degrader of interleukin-2-inducible T-cell kinase (ITK; DC50=3.6 nM in vivo in mice). ITK degrader 1 induces rapid, and prolonged ITK degradation and suppresses IL-2 secretion (EC50=35.2 nM, Jurkat cells) stimulated by anti-CD3 antibodyin vivo. ITK degrader 1 also shows good plasma exposure levels.

Description

ITK degrader 1 is a highly selective degrader of interleukin-2-inducible T-cell kinase (ITK; DC50=3.6 nM in vivo in mice). ITK degrader 1 induces rapid, and prolonged ITK degradation and suppresses IL-2 secretion (EC50=35.2 nM, Jurkat cells) stimulated by anti-CD3 antibodyin vivo. ITK degrader 1 also shows good plasma exposure levels[1].

In Vitro

ITK degrader 1 (compound 28) (0.001-3 μM; 12 h) dose-dependently decreases the protein levels of ITK in Jurkat cells[1].

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

Western Blot Analysis[1]

Cell Line: Jurkat cells
Concentration: 0.001 μM, 0.003 μM, 0.1 μM, 0.3 μM, 1 μM, 3 μM
Incubation Time: 12 h
Result: Exhibited strong ITK degradation potencies in a dose-dependent manner. Even rapidly led to significant ITK protein downregulation after 1 h incubation.
In Vivo

ITK degrader 1 (compound 28) (20 mg/kg; ip; single dose) significantly degrades ITK protein 2 h, 8 h, and 16 h after treatment on mice. ITK degrader 1 (25 mg/kg; ip; single dose) also inhibits inhibits IL-2 secretion 6 h after treatment in vivo in anti-CD3 monoclonal antibody (mAb)-induced IL-2 mouse model[1].

Animal Model: Balb/c mice, and anti-CD3 mAb-induced IL-2 mouse model[1]
Dosage: 20 mg/kg, 25 mg/kg
Administration: IP; singel dose
Result: Successfully delivered to the peripheral blood and spleen tissue, eliciting efficient, rapid, and prolonged ITK degradation starting at 2 h and lasting for at least 16 h with 20 mg/kg dose in Balb/c mice.
Efficiently suppressed the production of cytokine IL-2, resulting in a reduction of over 70% compared to the vehicle group with 25 mg/kg dose.

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.
