SGC0946 是一种选择性的DOT1L(histone 3 lysine 79 methyltransferase) 抑制剂,其IC50值为 0.3 nM。SGC0946 可通过抑制DOT1L,导致 G1 停滞以及抑制癌细胞的自我更新和转移潜力,诱导细胞分化。SGC0946 可用于白血病和乳腺癌的研究,也可作为探针以进一步研究DOT1L在正常和病变细胞中的细胞机制。
生物活性 | SGC0946 is a selectiveDOT1LH3K79 methyltransferase) inhibitor, with anIC50of 0.3 nM. SGC0946 results in G1 arrest, inhibits potential of cell self-renewal and metastatic, also induces cell differentiation. SGC0946 can be used in studies of leukemia and solid tumors and also serve as a probe to further investigate the cellular mechanism ofDOT1Lin both normal and diseased cells[1][2][3]. |

体外研究 (In Vitro) | SGC0946 (0-100 μM; 4 days) inhibits DOT1L with IC50of 2.65 nM in A431 cells[1]. SGC0946 (1, 5 μM; 14 days) displays selective reduction of cell viability in an experimental leukaemia model derived from human cord blood cells (transformed with the MLL-AF9 fusion oncogene)[1]. SGC0946 (1 μM; 3-7 days) shows time- and dose-dependent reductions in the H3K79me2 mark in the Molm13 MLL cell line that has the MLL/AF9 translocation[1]. SGC0946 (1 μM, 7 days) effectively inhibits MLL target genes, HOXA9 and Meis1[1]. SGC0946 (0.2, 2, or 20 μM; 12 days) reduces proliferation and survival of ovarian cancer cells by inhibiting DOT1L enzymatic activity[2]. SGC0946 (10 μM; 12 days) induces G1 phase arrest by blocking DOT1L in SK-OV-3 and TOV21G cells[2].
