GBD-9 是一种基于 E3 泛素连接酶 CRBN 的、靶向 BTK 及 G1 到 S 期过渡蛋白 GSPT1 的降解剂。GBD-9 通过诱导靶蛋白泛素化及蛋白酶体降解,兼具 PROTAC 与分子胶 () 特性。GBD-9 能高效降解野生型及突变型 BTK (如 C481S 突变) 和 GSPT1。GBD-9 通过诱导癌细胞 G1 期阻滞、下调抗凋亡蛋白 (BCL-2MCL-1) 并激活 Caspase-3 引发凋亡 (apoptosis),显著抑制肿瘤细胞增殖。GBD-9 主要用于弥漫性大 B 细胞淋巴瘤 (DLBCL)、急性髓系白血病 (AML) 等血液肿瘤的研究。
GBD-9 由 E3 泛素连接酶配体 (pink part) 5-Aminothalidomide (HY-W023573),靶蛋白配体 (blue part) Btk Inhibitor: IBT6A (HY-13036A),和 PROTAC linker (black part) Nonanoic acid (HY-N7057) 组成。

生物活性

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)[1][2][3].
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).

体外研究
(In Vitro)

GBD-9 (50 nM;24 h) 显著降解 DOHH2 细胞中 BTK 和 GSPT1,降解作用可被 20 μM Ibrutinib (HY-10997) 或 Pomalidomide (HY-10984) 阻断[2]
GBD-9 (10-1000 nM;72 h) 呈剂量依赖性抑制 DOHH2、WSU-NHL、HBL-1、THP-1、MV4-11 等细胞增殖,对 DOHH2 细胞的 IC50=133 nM,显著优于 Ibrutinib 和单靶点降解剂[2]
GBD-9 (10-100 nM;24 h) 诱导 DOHH2 细胞在 G1 期阻滞[2]

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

Cell Viability Assay[2]

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.

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.
