GNA002 |
| Catalog No.GC36168 |
GNA002 est un inhibiteur EZH2 (Enhancer of zeste homolog 2) très puissant, spécifique et covalent avec une IC50 de 1,1 μM. GNA002 peut se lier spécifiquement et de manière covalente À Cys668 dans le domaine EZH2-SET, déclenchant la dégradation de EZH2 par l'extrémité COOH de l'ubiquitination médiée par la protéine interagissant avec Hsp70 (CHIP). GNA002 réduit efficacement la triméthylation H3K27 médiée par EZH2, réactive les gènes suppresseurs de tumeurs silencieux du complexe répresseur polycomb 2 (PRC2).

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]. EZH2|1.1 μM (IC50)
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]. Cell Proliferation Assay[1] Cell Line: Numerous cancer cell lines
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]. Animal Model: Male BALB/C Nude mice aged 30-35 days and weighing 18-22 g, bearing Cal-27 xenograft tumors[1]
