產(chǎn)品簡(jiǎn)介:
Pictilisib 是一種PI3Kα/δ抑制劑,IC50為 3 nM。它對(duì)110β和 p110γ 具有適度的選擇性,分別為11倍和25倍。
GDC-0941是一種新的選擇性I類磷脂酰肌醇-3-激酶(PI3K)抑制劑。PI3K/Akt信號(hào)通路的激活通常與腫瘤發(fā)生有關(guān)。這種途徑的失調(diào)經(jīng)常發(fā)生在各種癌癥中,并可能導(dǎo)致對(duì)許多抗癌藥物的耐藥性。[1]開發(fā)特異性阻斷PI3K/Akt途徑的新型小分子可能會(huì)抑制腫瘤生長(zhǎng)。GDC-0941被設(shè)計(jì)為結(jié)合PI3K的ATP結(jié)合口袋,并防止磷脂酰肌醇-3,4,5-三磷酸(PIP3)的形成,pip 3是傳遞PI3K下游信號(hào)的第二信使。[2,3]它以ATP競(jìng)爭(zhēng)的方式與PI3K結(jié)合。
GDC-0941是一種有效的小分子噻吩并[3,2-d]嘧啶I類PI3K抑制劑。對(duì)亞型p110(和p110(IC50為3 nM)具有高度選擇性,對(duì)亞型p110(和p110(IC50分別為33 nM和75 nM)具有中等選擇性。 GDC-0941在體外和體內(nèi)抑制細(xì)胞增殖。它在多種癌細(xì)胞系中引起生長(zhǎng)抑制,包括A2780、MDA-MB-361、PC3和U87MG。[2]它還抑制對(duì)曲妥珠單抗敏感和耐藥的HER2擴(kuò)增癌細(xì)胞的生長(zhǎng),這些癌細(xì)胞含有p110(突變或PTEN缺失。[4] GDC-0941也減少了不同異種移植模型中的腫瘤體積。[4]
