 用途


RUNX1/ETO四聚-IN-1是RUNX1-ETO四聚的小分子抑制剂,具有抗白血病作用。RUNX1/ETO四聚体-IN-1专门针对RUNX1/ETO的NHR2(EC50=0.25μM),恢复RUNX1-ETO下调的基因表达。RUNX1/ETO四聚体-IN-1抑制依赖RUNX1-ETO的SKNO-1细胞的增殖,并降低小鼠模型中RUNX1_ETO相关肿瘤的生长[1][2][3]。

IC50: 630 μM (RUNX1-NHR2 tetramerization)[1]

体外研究 RUNX1/ETO由RUNX1基因产物DNA结合Runt-domain5和ETO基因产物四个神经同源区(NHR1-4)组成。NHR2结构域负责RUNX1/ETO的四聚反应。RUNX1/ETO四聚化-IN-1(化合物7.44)(1μM和10μM;3、5、7天)选择性地降低依赖RUNX1-ETO的人类白血病SKNO-1细胞的活性,而不是U937细胞[1]。RUNX1/ETO四聚体-IN-1(化合物7.44)(25μM和50μM;5d)抑制RUNX1-ETO表达细胞(SKNO-1、Kasumi-1和K562)的生长并诱导髓样分化[2]。RUNX1/ETO四聚体-IN-1(100μM;7 d)诱导表达RUNX1-ETOtr的CD34+祖细胞生长停滞和分化[2]。RUNX1/ETO四聚-IN-1(化合物7.44)具有良好的物理化学和ADME性质,具有高水溶性,在缓冲液和血浆中具有高稳定性,在体外肝内清除率低,水溶性为60μg/mL[3]。RUNX1/ETO四聚-IN-1(1μM和10μM)显示出抑制CYP2B6、2C9、2C19和3A4的潜力[3]。RUNX1/ETO四聚化-IN-1(化合物8)(50μM;16 h)抑制c-Jun N末端激酶(JNK)并影响细胞中的JNK途径[4]。细胞活力测定[1]细胞株:RUNX1/ETO依赖性人白血病SKNO-1和U937细胞浓度:1μM和10μM培养时间:3、5、7天结果:特异性抑制SKNO-1细胞生长。细胞存活率测定[3]细胞系:RUNX1/ETO四聚体-IN-1的药代动力学特性浓度:培养时间:结果:动力学溶解度(99%PBS,1%DMSO)177µM血浆蛋白结合(小鼠血浆,60分钟)98.4%血浆稳定性(小鼠等离子体,0–240分钟)无降解肝细胞稳定性(小鼠肝细胞)2.5µL/min/百万细胞PBS化学稳定性(0–4小时)无堕落
体内研究 RUNX1/ETO四聚体-IN-1(化合物7.44)(200-250μg/kg;i.p.;每周5次;130 d)延迟小鼠RUNX1-ETO细胞的肿瘤生长[2]。动物模型:注射Kasumi-1细胞的NSG免疫缺陷小鼠(NOD.Cg-Prkdcscid Il2rgtm1WjI/SzJ)[2]剂量:200-250μg/Kg给药:腹腔注射;每周5次,共130天。结果:减少了白血病细胞的传播,在治疗后第130天仍有75%的小鼠存活。
