UNC1999 生物活性

靶点	Histone Methyltransferase EZH2, IC50:2 nM EZH1, IC50:45 nM
描述	EZH2 or EZH1 is the catalytic subunit of the polycomb repressive complex 2 that catalyzes methylation of histone H3 lysine 27 (H3K27), which cause the gene expression silence. UNC1999 is a dual inhibitor of EZH2 and EZH1 with IC50 values of 2 nM and 45 nM (measured by PRC2 enzymatic activity)，respectively, and is over 1000-fold selective for other HMTs^[1]. UNC1999 (72h exposure) exhibited dose-dependent reductions in H3K27me3 with an IC50 value of 124 ± 11 nM in MCF10A cells bearing the WT EZH2 enzyme. The treatment of MCF7 cells with UNC1999 at 5,000 nM for 72 h almost completely removed the H3K27me3 mark but did not have significant effects on cellular levels of EZH2. UNC1999 selectively killed EZH2-mutant DLBCL cells with heterozygous for Y641 point mutations. Exposure of UNC1999 for 8 days displayed dose-dependent inhibition of cell proliferation with an EC50 of 633 ± 101 nM in DB cells, while 5,000 nM UNC1999 can completely killed DB cells. UNC1999 may be a good probe for EZH2 for biotinylated UNC1999 can be used to pull down EZH2 from cell lysates and UNC1999–dye conjugate co-localizes with EZH2 in live cells^[2]. Oral administration of UNC1999 (50 mg/kg, twice daily) starting from 7 days post-transplantation prolongs survival of a well-defined murine leukemia model bearing MLL-AF9, with significantly decreased H3K27me3 and elevated their p16Ink4a or p19Arf expression in cells isolated from bone marrow and spleen^[3].
作用机制	UNC1999 is a SAM-competitive inhibitor of EZH2 and EZH1^[2].

溶解方案

细胞实验：

DMSO: 105 mg/mL(184.29 mM)，配合低频超声助溶，注意：DMSO长时间开封后，会吸水并导致溶解能力下降，请避免使用长期开封的DMSO

动物实验：请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液，再依次添加助溶剂：
——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议现用现配，当天使用；以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶
