OTS193320 是一种咪唑并 [1,2-a] 吡啶化合物,一种SUV39H2甲基转移酶活性抑制剂。OTS193320 降低乳腺癌细胞中的全局组蛋白 H3 赖氨酸 9 三甲基化水平并引发凋亡细胞死亡。与单一药剂 OTS193320 或 DOX 相比,OTS193320 与 Doxorubicin (DOX; HY-15142A) 的组合可以导致 γ-H2AX 水平以及癌细胞活力的降低。
生物活性 | OTS193320, a imidazo[1,2-a]pyridine compound, is aSUV39H2 methyltransferaseactivity inhibitor. OTS193320 decreases global histone H3 lysine 9 tri-methylation levels in breastcancercells and triggersapoptoticcell death. Combination of OTS193320 withDoxorubicin(DOX; HY-15142A) results in reduction of γ-H2AX levels as well ascancercell viability compared to a single agent OTS193320 or DOX[1]. |
IC50& Target[1] | |
体外研究 (In Vitro) | OTS193320 (0.125-0.5 μM; 24 小时) 可以抑制乳腺癌细胞系的增殖。OTS193320 对 SUV39H2 阳性 A549 肺癌细胞具有生长抑制作用 (IC50=0.38 μM)[1]。 OTS193320 (0.5 μM; 48 小时) 诱导乳腺癌细胞凋亡[1]。 OTS193320 (0.125-0.5 μM; 24 小时) 以剂量依赖性方式降低 H3K9me3 水平[1]。 OTS193320 通过减弱 γ-H2AX 使乳腺癌细胞对多柔比星 (Doxorubicin) 敏感。与任一药物的单一药物治疗相比,OTS193320 和多柔比星的组合在体外显着降低癌细胞活力[1]。
