A series of oxazolo[4,5-g]quinazolin-2(1H)-one derivatives employing Erlotinib as lead compound were synthesized and evaluated for their EGFR inhibition activity. These compounds having variation at the 1 and 8-position, included ether and esters hydrophilic side-chain and aromatic head fragment, respectively. All these compounds were evaluated by EGFR inhibition and two anti-proliferation assays in vitro
合成了一系列以厄洛替尼为先导化合物的恶唑并[4,5 - g ]喹唑啉-2(1H)-一衍生物,并对其EGFR抑制活性进行了评估。这些在1位和8位具有变化的化合物分别包括醚和酯的亲水性侧链和芳族头部片段。所有这些化合物均通过EGFR抑制作用和两种体外抗增殖试验进行了评估。在EGFR-TK分析中,发现四种化合物比厄洛替尼更有效。此外,化合物18,42和50也具有良好的抗人表皮样癌细胞株(KB)和肾细胞癌的细胞系(A498)优良的抗增殖活性。最后,化合物50在小鼠刘易斯肺癌(LLC)异种移植模型中,与Erlotinib相比,在肿瘤生长方面具有明显更高的抑制作用。此外,化合物50在延长荷瘤小鼠的存活期方面显示出最显着的作用。
