    为了探索能够克服耐克唑替尼的突变体的新型ALK和ROS1双重抑制剂,设计,合成并评估了两个系列的2,4-二芳基氨基嘧啶衍生物的体外细胞毒性活性。在这项工作中,我们保留了2,4-二芳基氨基嘧啶骨架,并用磺酰基和丙烯酰胺基团衍生了DAAP骨架,以扩展结构-活性关系(SAR)研究。令我们高兴的是,某些化合物在MTT分析中显示出优异的抑制活性,其纳摩尔浓度达到两位数。进一步选择了四种化合物进行酶分析,结果鉴定出了有效的ALK和ROS1双重抑制剂X-17,针对ALK,ALK的IC 50值为3.7nM,2.3nM,8.9nM和1.9nM。分别为L1196M,ALK G1202R和ROS1。最终,在X-17上进行的分子对接研究清楚地揭示了与ALK的合理和最佳结合相互作用。

  • Modified PEG-anilinoquinazoline derivatives as potential EGFR PET agents
    作者:Samar Dissoki、Renana Eshet、Hana Billauer、Eyal Mishani
    DOI:10.1002/jlcr.1569
    日期:2009.2
    Inhibition of epidermal growth factor receptor tyrosine kinase (EGFR-TK) has emerged as a major approach for cancer-targeted therapy. Consequently, there has been a great interest in the use of labeled EGFR-TK inhibitors as positron emission tomography (PET) imaging agents. Currently, the developed agents did not yield adequate PET imaging of animal models probably due to poor solubility, rapid washout from blood, and low stability in vivo. In order to overcome these hurdles, new derivatives of previously reported inhibitors (ML04, 2) with decreased log P and increased solubility were designed and synthesized. These compounds (3–5) exhibited high autophosphorylation inhibitory potency with an IC50 of 5–35 nM, decreased log P's (3.1, 3.34, and 3.45, respectively), and significantly increased solubility (630, 300, and 120 µg/mL, respectively) relative to the previously reported parent compound 2 (log P=3.7, solubility=3.5 µg/mL). The labeling of compound 5 with [18F] and compounds 3 and 4 with [11C] and [124I], respectively, involved a one-step radiosynthesis. Compounds 3–5 were obtained with a total decay-corrected radiochemical yields of 13, 31, and 5%, respectively, and were found to be stable in blood. The positive outcome achieved with compounds 3–5 merits further in vivo evaluation as PET bioprobes. Copyright © 2008 John Wiley & Sons, Ltd.
    表皮生长因子受体酪氨酸激酶(EGFR-TK)的抑制已成为癌症靶向治疗的主要方法。因此,对于使用标记的EGFR-TK抑制剂作为正电子发射断层扫描(PET)成像剂产生了极大的兴趣。目前,开发的代理并未产生充分的动物模型的PET成像,可能由于其较差的溶解性、从血液中快速洗脱和在体内低稳定性。为了克服这些障碍,设计并合成了先前报道的抑制剂(ML04, 2)的新衍生物,这些衍生物具有减小的log P和增加的溶解性。这些化合物(3–5)显示出高的自磷酸化抑制效力,IC50值为5–35 nM,相对先前报道的母体化合物2(log P=3.7,溶解性=3.5 µg/mL),具有减小的log P(分别为3.1,3.34和3.45)和显著增加的溶解性(分别为630,300和120 µg/mL)。化合物5与[18F]、化合物3和4分别与[11C]和[124I]的标记涉及一步放射合成。化合物3–5获得的总衰变校正放射化学产率分别为13%,31%和5%,发现它们在血液中稳定。化合物3–5获得的正面结果值得进一步作为PET生物探针进行体内评估。版权所有 © 2008 John Wiley & Sons, Ltd.
