SCH 900776是Chk2和CDK2的低效抑制劑,IC50分別為1.5 μM 和 0.16 μM。SCH 900776對細(xì)胞色素P450人肝微粒體亞型1A2,2C9,2C19,2D6,和3A4沒有顯著的抑制作用。羥基脲下暴露24小時后,SCH 900776誘導(dǎo)DNA復(fù)制能力劑量依賴性損失。SCH 900776增強(qiáng)γ-H2AX對羥基脲,5-氟尿嘧啶,和阿糖孢苷的響應(yīng)。與抗代謝物結(jié)合,SCH 900776在2小時內(nèi)誘導(dǎo)γ-H2AX的累積,表明復(fù)制叉瓦解,并且雙鏈DNA斷裂。此外,SCH 900776以劑量依賴的方式抑制Chk1 pS296自磷酸化的積累。增殖的WS1細(xì)胞暴露于SCH 900776,與Chk1 pS345快速的,劑量依賴性聚集相關(guān),表明正常細(xì)胞的循環(huán)群誘導(dǎo)Chk1 pS345在暴露于SCH 900776后,是一部分無效循環(huán),這也許通過AT-家族激酶和DNA-PK驅(qū)動。[1]
