体外研究(In Vitro)
体外研究活性 AT-406是一种Smac模拟物,在氢键结合以及与XIAP的疏水性相互作用中,似乎能够很接近地模拟AVPI多肽,伴随额外的与XIAP的W323疏水性接触。AT-406对这些IAPs比对Smac AVPI多肽更敏感,具有50-100倍的结合亲和力。AT-406 (1 μM)完全恢复caspase-9的活性,其在无细胞体系中被500 nM XIAP BIR3抑制。在MDA-MB-231细胞中,AT-406诱导快速的细胞cIAP1降解,并摧毁细胞XIAP蛋白。AT-406有效抑制大量人癌症细胞系,在MDA-MB-231细胞和SK-OV-3卵巢癌细胞中,IC50分别为144和142 nM,对正常人乳腺样上皮MCF-12F细胞和初级人正常前列腺上皮细胞具有低毒性。在MDA-MB-231细胞中,AT-406通过诱导caspase-3活化和PARP裂解,诱导细胞凋亡。[1]
激酶实验 XIAP,cIAP1,和 cIAP2 BIR3 蛋白质的荧光偏振试验
FL-AT-406(荧光标记的AT-406)用于开发一组新的FP试验,用于测定Smac模拟物对XIAP,cIAP-1,和cIAP-2 BIR3蛋白质的结合亲和力。FL-AT-406对每种IAP蛋白质的Kd值通过滴定实验使用固定浓度的FL-AT-406和不同浓度直到饱和的蛋白质进行测定。荧光偏振值使用Infinite M-1000酶标仪在Microfluor296孔,黑色,圆底板中测量。对每个孔,加入FL-AT-406 (对XIAP BIR3,cIAP-1 BIR3,和cIAP-2 BIR3的实验分别为2,1,和1 nM)和不同浓度的蛋白质,在测定缓冲液(100 mM磷酸钾,pH 7.5,100 μg/mL牛γ-球蛋白,0.02%叠氮化钠,和4% DMSO)中终体积为125 μL。将板混合,并在室温下温和摇晃培育2-3小时。毫极化单元(mP)中的偏振值在485 nm激发波长和530 nm发射波长下测量。随后,平衡解离常数(Kd)使用Graphpad Prism 5.0软件,根据蛋白质浓度对剂量依赖性FP的增加通过S形曲线拟合进行计算。在XIAP3 BIR3的竞争性结合实验中,AT-406与20 nM XIAP BIR3蛋白质和2 nM FL-AT-406在试验缓冲液(100 mM磷酸钾,pH 7.5;100 μg/mL 牛γ-球蛋白;0.02% 叠氮化钠)中进行培育。在cIAP1 BIR3蛋白质竞争性结合实验中,使用3 nM蛋白质和1 nM FL-AT-406。对于cIAP2 BIR3竞争性结合实验,使用5 nM蛋白质和1 nM FL-AT-406。对每个竞争性结合实验,偏振值在培育2-3小时之后使用Infinite M-1000酶标仪测量。IC50值,50%结合示踪物被取代时的抑制剂浓度,根据绘图使用非线性最小二乘法分析计算。曲线拟合使用PRISM软件进行。计算AT-406的Ki值。

浓度 ~ 1 μM
孵育时间 4天
方法

细胞以(3-4)×103细胞/孔的密度与AT-406接种在96孔平底细胞培养板,并培育4天。不同浓度AT-406处理后的细胞生长抑制率通过(2-(2-甲氧基-4-硝基苯基)-3-(4-硝基苯基)-5-(2,4-二磺苯基)-2H-四唑谷氨酸盐 (WST-8)分析测定。将WST-8加入每孔,终浓度为10%,然后板在37 °C下培育2-3小时。样品吸光度在450 nm下使用TECAN ULTRA阅读器测量。抑制50%细胞生长的AT-406浓度(IC50)通过比较未处理细胞和AT-406处理细胞的吸光度计算。
