體外研究(In Vitro)
體外研究活性 AT-406是一種Smac模擬物,在氫鍵結(jié)合以及與XIAP的疏水性相互作用中,似乎能夠很接近地模擬AVPI多肽,伴隨額外的與XIAP的W323疏水性接觸。AT-406對這些IAPs比對Smac AVPI多肽更敏感,具有50-100倍的結(jié)合親和力。AT-406 (1 μM)完全恢復caspase-9的活性,其在無細胞體系中被500 nM XIAP BIR3抑制。在MDA-MB-231細胞中,AT-406誘導快速的細胞cIAP1降解,并摧毀細胞XIAP蛋白。AT-406有效抑制大量人癌癥細胞系,在MDA-MB-231細胞和SK-OV-3卵巢癌細胞中,IC50分別為144和142 nM,對正常人乳腺樣上皮MCF-12F細胞和初級人正常前列腺上皮細胞具有低毒性。在MDA-MB-231細胞中,AT-406通過誘導caspase-3活化和PARP裂解,誘導細胞凋亡。[1]
激酶實驗 XIAP,cIAP1,和 cIAP2 BIR3 蛋白質(zhì)的熒光偏振試驗
FL-AT-406(熒光標記的AT-406)用于開發(fā)一組新的FP試驗,用于測定Smac模擬物對XIAP,cIAP-1,和cIAP-2 BIR3蛋白質(zhì)的結(jié)合親和力。FL-AT-406對每種IAP蛋白質(zhì)的Kd值通過滴定實驗使用固定濃度的FL-AT-406和不同濃度直到飽和的蛋白質(zhì)進行測定。熒光偏振值使用Infinite M-1000酶標儀在Microfluor296孔,黑色,圓底板中測量。對每個孔,加入FL-AT-406 (對XIAP BIR3,cIAP-1 BIR3,和cIAP-2 BIR3的實驗分別為2,1,和1 nM)和不同濃度的蛋白質(zhì),在測定緩沖液(100 mM磷酸鉀,pH 7.5,100 μg/mL牛γ-球蛋白,0.02%疊氮化鈉,和4% DMSO)中終體積為125 μL。將板混合,并在室溫下溫和搖晃培育2-3小時。毫極化單元(mP)中的偏振值在485 nm激發(fā)波長和530 nm發(fā)射波長下測量。隨后,平衡解離常數(shù)(Kd)使用Graphpad Prism 5.0軟件,根據(jù)蛋白質(zhì)濃度對劑量依賴性FP的增加通過S形曲線擬合進行計算。在XIAP3 BIR3的競爭性結(jié)合實驗中,AT-406與20 nM XIAP BIR3蛋白質(zhì)和2 nM FL-AT-406在試驗緩沖液(100 mM磷酸鉀,pH 7.5;100 μg/mL 牛γ-球蛋白;0.02% 疊氮化鈉)中進行培育。在cIAP1 BIR3蛋白質(zhì)競爭性結(jié)合實驗中,使用3 nM蛋白質(zhì)和1 nM FL-AT-406。對于cIAP2 BIR3競爭性結(jié)合實驗,使用5 nM蛋白質(zhì)和1 nM FL-AT-406。對每個競爭性結(jié)合實驗,偏振值在培育2-3小時之后使用Infinite M-1000酶標儀測量。IC50值,50%結(jié)合示蹤物被取代時的抑制劑濃度,根據(jù)繪圖使用非線性最小二乘法分析計算。曲線擬合使用PRISM軟件進行。計算AT-406的Ki值。
細胞實驗 細胞系 MDA-MB-231乳腺癌和 SK-OV-3 卵巢癌細胞系
濃度 ~ 1 μM
孵育時間 4天
方法

細胞以(3-4)×103細胞/孔的密度與AT-406接種在96孔平底細胞培養(yǎng)板,并培育4天。不同濃度AT-406處理后的細胞生長抑制率通過(2-(2-甲氧基-4-硝基苯基)-3-(4-硝基苯基)-5-(2,4-二磺苯基)-2H-四唑谷氨酸鹽 (WST-8)分析測定。將WST-8加入每孔,終濃度為10%,然后板在37 °C下培育2-3小時。樣品吸光度在450 nm下使用TECAN ULTRA閱讀器測量。抑制50%細胞生長的AT-406濃度(IC50)通過比較未處理細胞和AT-406處理細胞的吸光度計算。
