BSJ-05-037
Based on 1 Customer Validation
BSJ-05-037 is an ITK PROTAC degrader that effectively targets and degrades ITK in T-cell lymphoma cell lines. BSJ-05-037 blocks the activation of the NF-κB/GATA-3 signaling pathway, inhibits PLCγ1 phosphorylation, and reduces the proliferative capacity of T-cell lymphoma cells. BSJ-05-037 enhances the sensitivity of T-cell lymphoma cells to chemotherapy. In mouse models of T-cell lymphoma, BSJ-05-037 induces ITK degradation, reduces GATA-3 expression, decreases tumor volume, and reverses chemotherapy resistance. BSJ-05-037 is applicable to research related to T-cell lymphoma.
(Pink: Itk ligand (HY-11092); Blue: Cereblon ligand (HY-103597); Black: linker (HY-W036393)).

BSJ-05-037 (0.001-10 μM; 2-16 h) potently induces time- and concentration-dependent degradation of ITK in DERL-2 and Hut78 cells, and this degradation is CRBN-dependent[1].
BSJ-05-037 (1 μM; 10 days) potently inhibits the proliferation of DERL-2 and Jurkat T-cell lymphoma cells[1].
BSJ-05-037 (0.025-0.5 μM; 8 h) dose-dependently inhibits the phosphorylation of PLCγ1 in DERL-2 cells[1].
BSJ-05-037 (1 μM; 24 h-3 days) blocks TCR-induced upregulation of GATA-3 and restores the sensitivity of T8ML-1 cells to Vincristine (HY-N0488A), thereby overcoming drug resistance mediated by the ITK/NF-κB/GATA-3 axis[1].
BSJ-05-037 (1 μM; 24 h-4 days) induces nearly complete ITK degradation and reduces GATA-3 levels by over 90% in Hut78 and H9 cutaneous T-cell lymphoma cells, while also enhancing the sensitivity of these cells to Vincristine during the 4-day treatment[1].
