说明

一般說明

A cell-permeable EI1 (Cat. No. 500561) structural analog that acts as an equally potent, SAM-competitive, Ezh2/PRC2 inhibitor (Ki = 0.5 to 3 nM against wt & mutant Ezh2-containing PRC2; [SAM] = 7.5 µM) with similar selectivity over Ezh1/PRC2 (Ki = 89 nM) and other HTMases as EI1. Among panels of 14 HDACs, 11 GPCRs, and 300 kinases, only serotonin 3 receptor, JMJD2d, and CaMK1a are significantly inhibited at much higher concentrations (IC50 ≥4 µM). Shown to inhibit the proliferation of DLBCL (IC50 28 nM to 5.5 µM; 6 d treatment) in vitro and completely suppress Pfeiffer (A677G) and Karpas-422 (Y641N) tumor expansion in mice in vivo (50 mg/kg/d i.p.). In addition to DLBCL (diffuse large B cell lymphoma; IC50 ranges from 28 nM to 5.5 µM; 6 d treatment), GSK126 is also shown to inhibit the proliferation of other B-NHL (non-Hodgkin′s lymphoma) and Hodgkin′s lymphoma cell lines, being least active against MC116, HD-MY-Z, WSU-FSCCL, Toledo, NU-DUL-1, and WILL-2 (IC50 >10 µM; 6 d treatment). When administered at a daily i.p. dose of 50 mg/kg, GSK126 is reported to completely suppress Pfeiffer (A677G) and Karpas-422 (Y641N) tumor expansion in mice in vivo, while complete tumor eradication can be achieved with higher dosing regimens (150 mg/kg/day or two 300 mg/kg dosages per week). It has been demonstrated to regulate the EZH2-PAX6-CXCL10 pathway, thereby suppressing myocardial fibrosis. Additionally, GSK126 has been observed to inhibit apoptosis and reduce H3K27me3 levels in the brains of rat models.

應用

GSK126, Ezh2 Inhibitor III has been used:

• in testing the epigenetic interactions for the formation of single-cell domains.
• to induce hyper histone methylation in IMR-90 cells.
