UBX-382

Customer Review

Based on 1 Customer Validation

UBX-382 is an orally active BTK PROTAC degrader with a DC₅₀ of 4.56 nM. UBX-382 inhibits B-cell receptor signaling by targeting BTK. UBX-382 shows superior degradation activity for wild-type and mutant BTK proteins. UBX-382 inhibits tumor growth in murine xenograft models harboring wild-type or C481S mutant BTK-expressing TMD-8 cells. UBX-382 can be used for the study of B-cell-related blood cancers.

In Vitro

UBX-382 (0.00001-10 nM, 0.5-48 h) induces potent BTK degradation with a DC ₅₀ of 4.56 nM in TMD-8 cells^[1].
UBX-382 (0.0001-10 μM, 3-5 days) inhibits the proliferation of TMD8 (IC₅₀ = 14 nM), WSU-DLCL2 (IC₅₀ = 18 nM), OCI-Ly3 (IC₅₀ = 199 nM) and U2932 (IC₅₀ = 21 nM) measured by the Cell Titer-Glo assay in duplicates^[1].
UBX-382 (10 nM, 24 h) significantly inhibits CCL3 and CCL4 secretion induced by BCR signal activation in TMD-8 cells^[1].
UBX-382 (100 nM, 6-24 h) inhibits the phosphorylation of BTK Y223, SYK, MEK, and ERK in U2932 cells^[1].
UBX-382 (0.1-10 μM, 24 h) effectively degrades wild-type and various BTK mutants (E41K, C481S/R/T/Y/F, L528W) in HEK293 cells and strongly suppresses their phosphorylation^[1].

Western Blot Analysis^[1]

Cell Line:

U2932 cells
Concentration:

100 nM
Incubation Time:

6, 24 h
Result:

Showed far more effective inhibition of BTK Y223 phosphorylation than Ibrutinib (HY-10997), Acalabrutinib (HY-17600), and Nemtabrutinib (ARQ-531) (HY-112215) in U2932 cells.
Inhibited the phosphorylation of SYK, MEK, and ERK.

In Vivo

UBX-382 (3-30 mg/kg, p.o., once daily, 21 days) inhibits the growth of tumor in TMD-8 xenograft models and TMD-8 BTK C481S xenograft model^[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 Matrigel) were subcutaneously injected into the flanks of 6-week-old CB17/severe combined immunodeficient mice^[1]
Dosage:

3, 10, 30 mg/kg
Administration:

p.o. once daily for 21 days
Result:

Achieved complete tumor regression in TMD-8 xenograft models.
Showed no significant changes in body weight and no other clinical toxicity signs during the experiment.
Reduced BTK levels in tumors of TMD-8 xenograft models.

Animal Model:

TMD-8 BTK C481S cells were subcutaneously inoculated into the right flank of male CB17/severe combined immunodeficient mice^[1]
Dosage:

3, 10, 30 mg/kg
Administration:

p.o. once daily for 21 days
Result:

Induced remarkable dose-dependent tumor regression in TMD-8 BTK C481S xenograft models, while Ibrutinib failed to inhibit tumor growth.

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.
