产品使用指南

GNA002 是一种有效,选择性的,共价 EZH2 抑制剂,对 EZH2IC50 为1.1 μM。GNA002 可以特异性,共价结合 EZH2-SET 结构域内的 Cys668,通过 Hsp70 相互作用蛋白 (CHIP) 介导的泛素化的 COOH 末端引发 EZH2 降解。GNA002 有效降低 EZH2 介导的 H3K27 三甲基化,重新激活 polycomb 阻遏复合物 2 (PRC2) 沉默的肿瘤抑制基因。

生物活性

GNA002 is a highly potent, specific and covalent EZH2 (Enhancer of zeste homolog 2) inhibitor with an IC50 of 1.1 μM. GNA002 can specifically and covalently bind to Cys668 within the EZH2-SET domain, triggering EZH2 degradation through COOH terminus of Hsp70-interacting protein (CHIP)-mediated ubiquitination. GNA002 efficiently reduces EZH2-mediated H3K27 trimethylation, reactivates polycomb repressor complex 2 (PRC2)-silenced tumor suppressor genes[1].

IC50 & Target[1]

EZH2

1.1 μM (IC50)

体外研究
(In Vitro)

GNA002 (10 μM; 72 hours) clearly inhibits the proliferation of numerous cancer cell lines with IC50s of 0.070 μM and 0.103 μM for MV4-11 and RS4-11[1].
GNA002 (2 μM; 24 hours) demonstrates an elevated capacity to induce cell death in human cancer cells[1].
GNA002 (0.1-4 μM; 48 hours) efficiently reduces EZH2-mediated H3K27 trimethylation in Cal-27 head and neck cancer cells[1].

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

Cell Proliferation Assay[1]

Cell Line: Numerous cancer cell lines
Concentration: 10 μM
Incubation Time: 72 hours
Result: Inhibited the proliferation of numerous cancer cell lines with IC50s of 0.070 μM and 0.103 μM for MV4-11 and RS4-11.

Apoptosis Analysis[1]

Cell Line: HN-4 and Cal-27 head and neck cancer cells
Concentration: 2 μM
Incubation Time: 24 hours
Result: Induced cellular apoptosis in human cancer cells.

Western Blot Analysis[1]

Cell Line: Cal-27 head and neck cancer cells
Concentration: 0.1, 0.2, 0.5, 1, 2, 4 μM
Incubation Time: 48 hours
Result: Reduced H3K27Me3 levels.
体内研究
(In Vivo)

GNA002 (oral administration; 100 mg/kg; daily) significantly decreases the volumes of Cal-27-derived tumors and reduces H3K27Me3 levels in tumor tissues. GNA002 also significantly suppresses the in vivo tumor growth derived from the xenografted A549 lung cancer cells, Daudi and Pfeiffer cells. GNA002 inhibits the aberrant oncogenic functions of EZH2, thus inhibiting tumor growth in vivo, at least in the xenograft experimental model[1].

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

Animal Model: Male BALB/C Nude mice aged 30-35 days and weighing 18-22 g, bearing Cal-27 xenograft tumors[1]
Dosage: 100 mg/kg
Administration: Oral administration; daily
Result: Decreased the size and weight of tumors formed by Cal-27 cells.
