      生物活性

      產品描述 GSK461364 (GSK461364A)抑制純化的Plk1,無細胞試驗中Ki為2 nM。比作用于Plk2/3選擇性高1000倍。
      特性 GSK461364是有效的,可逆的ATP競爭性的Plk1選擇性抑制劑,作用于Plk1比作用于Plk2和Plk3選擇性至少高390倍,而比作用于一組48種其他激酶選擇性高1×103倍。

      GSK461364作用于非細胞分裂細胞,從多起點抑制癌細胞系增殖。[1] 野生型p53的RNA沉默提高GSK461364的抗增殖活性。許多癌癥療法對p53野生型患者更有效, p53缺陷腫瘤對GSK461364的高度敏感性可提供治療腫瘤的機會。GSK461364是噻吩酰胺,在體外,抑制純化的Plk1酶,Ki為2 nM,作用于Plk1比作用于 Plk2和 Plk3選擇性高100多倍。GSK461364是有效的細胞增殖抑制劑,低于100 nM 時作用于大部分細胞系,抑制50% 生長(GI50),作用于人無增殖細胞系具有有限的毒性。GSK461364抑制細胞周期進展是濃度依賴性的,高濃度時,使細胞在G2期發(fā)生延遲,較低濃度時使細胞停在M 期。目前, GSK461364按劑量遞增方式首次用在人體試驗階段。攜帶TP53基因突變的細胞系對 GSK461364更敏感,且作用于一些p53野生型(WT)細胞,通過RNA沉默抑制p53 反應,使敏感性增加。而且, 這些更敏感的細胞系染色體不穩(wěn)定性提高,這是與TP53突變相關的一個特點。[2] 在臨床前期研究中, GSK461364作用于多種(>120)腫瘤細胞系,具有抗增殖活性,且有效抑制這些細胞系中的 83%和91%細胞增殖,IC50分別低于50和100 nM。[3]

      孵育時間 72小時
      方法

      癌細胞系接種在384孔板上。細胞在37oC下溫育24小時。每孔加入GSK461364,濃度為10 nM。測定每組細胞系在T=0的實驗值。72小時后,從殘留細胞中抽提含GSK461364或DMSO的培養(yǎng)基,用4',6-二脒基-2-苯基吲哚進行核染色,使用 InCell1000 高通量分析儀測定熒光密度。在72小時時,計算每種濃度GSK461364在重復三次孔的每個孔中中,4',6-二脒基-2-苯基吲哚染色強度相對T=0時強度的百分數(shù)。

      GSK461364作用于培養(yǎng)細胞的生長,可以抑制細胞生長或產生細胞毒性,但在適當劑量處理下,可以導致移植瘤模型發(fā)生腫瘤衰退。GSK461364 作用于移植瘤模型,具有明顯的抗癌活性。[1] GSK461364作用于小鼠移植瘤,使細胞周期停滯,這種作用存在劑量依賴性,與作用于腫瘤生長相關。[2] GSK461364腹腔注射處理不同移植瘤模型,包括Colo205移植瘤,導致衰退或腫瘤生長延遲。在體內,使用GSK461364抑制Plk1,導致有絲分裂停滯,形成由單極或倒塌的有絲分裂紡錘體組成的異常有絲分裂。[3]
