GBD-9
Based on 1 Customer Validation
GBD-9 is a degrader based on the E3 ubiquitin ligase CRBN that targets BTK and the G1 to S phase transition protein GSPT1. GBD-9 has both PROTAC and molecular glue properties by inducing ubiquitination and proteasomal degradation of target proteins. GBD-9 can efficiently degrade wild-type and mutant BTK (such as C481S mutation) and GSPT1. GBD-9 significantly inhibits tumor cell proliferation by inducing G1 phase arrest in cancer cells, downregulating anti-apoptotic proteins (BCL-2, MCL-1) and activating Caspase-3 to induce apoptosis. GBD-9 is mainly used in the research of hematological tumors such as diffuse large B-cell lymphoma (DLBCL) and acute myeloid leukemia (AML).
GBD-9 is composed of E3 ubiquitin ligase ligand (pink part) 5-Aminothalidomide (HY-W023573), target protein ligand (blue part) Btk Inhibitor: IBT6A (HY-13036A), and PROTAC linker (black part) Nonanoic acid (HY-N7057).

Cereblon |
GBD-9 (50 nM; 24 h) significantly degrades BTK and GSPT1 in DOHH2 cells, and the degradation could be blocked by 20 μM Ibrutinib (HY-10997) or Pomalidomide (HY-10984)[1].
GBD-9 (10-1000 nM; 72 h) inhibits the proliferation of DOHH2, WSU-NHL, HBL-1, THP-1, MV4-11 and other cells in a dose-dependent manner, with an IC50 of 133 nM for DOHH2 cells, which is significantly superior to Ibrutinib and single-target degraders[1].
GBD-9 (10-100 nM; 24 h) induces G1 arrest in DOHH2 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:DOHH2 (DLBCL cell line)
-
Concentration:50 nM, 100 nM
-
Incubation Time:24 h (50 nM), 4 h (100 nM)
-
Result:Reduced BTK and GSPT1 protein levels to <20% of baseline at 50 μM, 4 h, with complete abrogation of BTK degradation when co-treated with Ibrutinib (20 μM), and loss of GSPT1 degradation when co-treated with pomalidomide (20 μM), confirming dependency on BTK binding and CRBN recruitment.
