基于結(jié)構(gòu)設(shè)計(jì)的新型mTOR抑制劑的抗宮頸癌活性研究(英文)
發(fā)布時(shí)間:2021-11-10 06:03
激酶mTOR是PI3K-AKT信號通路的關(guān)鍵組成部分,該激酶在宮頸癌細(xì)胞中被高度激活。本文運(yùn)用基于結(jié)構(gòu)的藥物發(fā)現(xiàn)等手段發(fā)現(xiàn)了一系列mTOR激酶抑制劑并對其進(jìn)行生物學(xué)評價(jià),發(fā)現(xiàn)其可發(fā)揮有效的抗宮頸癌作用。酶活性測定結(jié)果顯示化合物C3具有潛在的mTOR抑制作用(IC50=1.57μM)。隨后利用分子對接和動(dòng)力學(xué)模擬探究并預(yù)測m TOR激酶和C3的結(jié)合模式,初步探討了化合物的構(gòu)效關(guān)系。在多種腫瘤細(xì)胞系上進(jìn)行細(xì)胞增殖活性實(shí)驗(yàn)時(shí)發(fā)現(xiàn),C3對宮頸癌細(xì)胞He La表現(xiàn)出較好的增殖抑制活性(IC50=0.38μM)。此外, C3還能濃度依賴性地降低磷酸化核糖體S6 (p-S6)蛋白在HeLa細(xì)胞內(nèi)的表達(dá)水平。值得注意的是,C3發(fā)揮顯著的抗宮頸癌活性很有可能是mTOR通路和其他細(xì)胞內(nèi)通路的共同作用。本研究表明C3可進(jìn)一步開發(fā)為宮頸癌的治療藥物。
