DMXAA(Vadimezan,AS-1404)是一种选择性的DT-黄递酶抑制剂,Ki值和IC50值分别为20 μM和62.5 μM[1,2]。
DT-黄递酶(DTD)是一种专性的二电子还原酶。据报道,在多种癌症中,DTD的表达升高[2]。
DMXAA(Vadimezan)是一种有效的DT-黄递酶抑制剂,也是几个激酶的多靶点抑制剂。在C57Bl/6小鼠来源的38个肿瘤中,DMXAA(Vadimezan)(25 mg/kg)在给药30分钟后显著诱导内皮细胞的凋亡,而在给药3小时后显示强烈的凋亡血管和肿瘤的大面积坏死[2]。在NSCLC细胞系A549细胞中,DMXAA(Vadimezan)(0.1-10 μM)以剂量依赖的方式增加细胞色素的胞质水平和caspase3的激活,从而诱导G1期停滞、细胞凋亡和自噬[3]。
在表达荧光素酶的小鼠GL261胶质瘤细胞皮下异种移植C57Bl/6小鼠模型中,DMXAA(Vadimezan)(25 mg/kg)导致24小时时广泛的细胞坏死,9天的生长延迟和50%小鼠完全的肿瘤消退。而且,与lenalidomide(100 mg/kg)联合给药可显著增加生长延迟和治愈百分比,分别增加到20天和83 %[4]。
据报道,DMXAA(Vadimezan)是几个激酶的多靶点抑制剂,对血管内皮生长因子受体(VEGFR)酪氨酸激酶家族的成员具有最强的效应。在斑马鱼胚胎和人脐静脉内皮细胞(HUVECs)中,DMXAA(Vadimezan)阻断血管生成和VEGFR2信号[5]。

一般建议 | 不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
细胞实验: [1] | |
细胞系 |
HECPP细胞 |
制备方法 |
该化合物在DMSO中的溶解度大于10 mM,若配制更高浓度的溶液,一般步骤如下:请将试管置于37℃加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20℃可放置数月。 |
反应条件 |
IC50:500 μg/mL,24 hours |
实验结果 |
在HECPP细胞中,DMXAA不诱导TNF或干扰素的mRNA。400 μg/mL的DMXAA孵育2小时后,IP-10的mRNA上调。400 μg/mL的DMXAA孵育6小时后观察到凋亡细胞,凋亡数量随着时间延长而增加。高于100 μg/mL浓度下,24小时的凋亡细胞数量随着DMXAA的剂量增加成线性增加。500 μg/mL 的DMXAA孵育24小时后诱导50%的凋亡。 |
动物实验: [2] | |
动物模型 |

给药剂量 |
腹腔注射,25 mg/kg |
实验结果 |
一旦肿瘤建立(皮下肿瘤,第7天或第14天)后,腹腔给药5 mg/kg的DMXAA。在6和24小时进行BLI。344SQ-ELuc NSCLC皮下肿瘤对DMXAA快速响应,药物注射后生物发光(BLI)信号的标记减少约2-logs。在DMXAA处理后BLI的下降不是由于直接的肿瘤细胞毒性作用,因为DMXAA对344SQ-ELuc细胞活力没有不利影响。 |
注意事项 |
请于室内测试所有化合物的溶解度。虽然化合物的实际溶解度可能与其理论值略有不同,但仍处于实验系统误差的允许范围内。 |
