TQ-3959

TQ-3959 is an orally active BTK PROTAC degrader, with a DC₅₀ of 14.6 nM. TQ-3959 exerts antiproliferative activity against both wild-type BTK and C481S mutant BTK cell lines. TQ-3959 exhibits tumor growth inhibition in female NOD-SCID mice bearing TMD-8 xenografts. TQ-3959 can be used in the research on B-cell malignancies such as lymphoma.

In Vitro

TQ-3959 exhibits potent BTK degradation activity with a DC₅₀ of 0.4 nM and a D_max of 97.7% in OCI-Ly10 cells via HTRF assay^[1].
TQ-3959 (72 h) shows antiproliferative activity against OCI-Ly10 (BTK ^WT cells) (IC₅₀ = 0.08 nM), TMD-8 (BTK ^WT cells) (IC₅₀ = 1.0 nM), OCI-Ly10 (BTK ^C481S cells) (IC₅₀ = 0.2 nM), and TMD-8 (BTK ^C481S cells) (IC₅₀ = 0.6 nM)^[1].

In Vivo

TQ-3959 (7.5-30 mg/kg, p.o., once daily, 20 days) exhibits tumor growth inhibition in female NOD-SCID mice bearing TMD-8 xenografts^[1].

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

Animal Model:

TMD-8 cells (1 × 10⁷ in 100 μL) were subcutaneously implanted into the right flanks of 6-8-week-old female NOD-SCID mice^[1]
Dosage:

7.5, 15, 30 mg/kg
Administration:

p.o. once daily for 20 days
Result:

Achieved tumor growth inhibition (TGI) rates of 80.5%, 98.5%, and 98.8% at oral doses of 7.5, 15, and 30 mg/kg in female NOD-SCID mice bearing TMD-8 xenografts, respectively.
Showed no significant changes in body weight.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
