   RO4929097是γ分泌酶的小分子抑制劑，IC50為4 nM，EC50為5 nM [1]。它對(duì)密切相關(guān)的蛋白酶沒(méi)有體外抑制活性。它還對(duì)75種不同類型的其他蛋白質(zhì)具有超過(guò)100倍的選擇性[1]。RO4929097結(jié)合γ分泌酶并抑制其蛋白酶活性，因此阻斷Notch的切割并減少Notch信號(hào)。這種信號(hào)通路的上調(diào)促進(jìn)多種癌癥的腫瘤發(fā)生。

   RO4929097在體外和體內(nèi)都顯示出潛在的抗腫瘤活性。它損害了黑色素瘤細(xì)胞系的生長(zhǎng)和人類原發(fā)性黑色素瘤異種移植物的腫瘤形成[2]。它減緩了乳腺癌細(xì)胞系的增殖并減少了集落形成[1]。此外，RO4929097減少了結(jié)腸直腸、胰腺、肺癌和黑色素瘤異種移植模型中的腫瘤形成[1，2]。RO4929097已經(jīng)在晚期實(shí)體瘤患者的多個(gè)I/II期臨床試驗(yàn)中進(jìn)行了測(cè)試，作為單一療法或與其他抗腫瘤藥物聯(lián)合使用[3-8]。
