GNA002 is a highly potent, specific and covalent EZH2 (Enhancer of zeste homolog 2) inhibitor with an IC 50 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 In Vitro GNA002 (10 μM; 72 hours) clearly inhibits the proliferation of numerous cancer cell lines with IC 50 s of 0.070 μM and 0.103 μM for MV4-11 and RS4-11. GNA002 (2 μM; 24 hours) demonstrates an elevated capacity to induce cell death in human cancer cells. GNA002 (0.1-4 μM; 48 hours) efficiently reduces EZH2-mediated H3K27 trimethylation in Cal-27 head and neck cancer cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Proliferation AssayCell 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 AnalysisCell 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 AnalysisCell 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. 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 . 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 Dosage: 100 mg/kg Administration: Oral administration; daily Result: Decreased the size and weight of tumors formed by Cal-27 cells. Form:Oil IC50& Target:EZH2 1.1 μM (IC 50 )
