Disclosed in the present disclosure are a pyrimidine-fused cyclic compound or a pharmaceutically acceptable salt, hydrate, prodrug, stereoisomer, solvate or isotope labeled compound thereof. Also provided in the present disclosure are a preparation method for the compound, a composition comprising the compound and a use of the compound for the preparation of a medicament for the prevention and/or treatment of a disease or condition associated with abnormal SHP2 activity.
8-substituted imidazo[1,2-c]pyrimidine-5(6H)-ones (ethenocytosines). Starting ethenocytosines were obtained by cyclization of 5-halogenocytosines with chloroacetaldehyde or by subsequent Suzuki–Miyaura cross-coupling between 8-iodoimidazo[1,2-c]pyrimidine-5(6H)-one 1d and corresponding arylboronic acids. When imidazo[1,2-c]pyrimidine-5(6H)-one or 8-iodoimidazo[1,2-c]pyrimidine-5(6H)-one 1d was iodinated
我们描述了各种8-取代的咪唑并[1,2 - c ]嘧啶-5(6 H)-ones(ethenocytosines)的温和和选择性碘化。通过将5-卤代胞嘧啶与氯乙醛环化或随后的Suzuki-Miyaura交叉偶联在8-碘咪唑并[1,2 - c ]嘧啶-5(6 H)-1d和相应的芳基硼酸中获得起始的胞嘧啶。当咪唑并[1,2 Ç ]嘧啶5(6 ħ) -酮或8碘咪唑并[1,2- c ^ ]嘧啶5(6 ħ) -酮1D通过碘化Ñ在DMF碘代丁二酰亚胺(NIS) ,纯3,8-二碘代衍生物2d获得了。在碱性或酸性条件下,该分子会重排为2,8-二十二烷基衍生物3d,随后可将其碘代为2,3,8-三十二烷基衍生物4d。由于仅通过NMR光谱不能令人信服地确定碘原子在咪唑环上的位置,因此对2d进行X射线分析以毫无疑问地确认其结构。将相同的反应顺序应用于另外八个乙炔胞嘧啶,可提供出色的区域选择性,易重排和高产率的碘化产物。通过1
New Imidazo[1,2-<i>c</i>]pyrimidin-5(6<i>H</i>)-Ones Derived from Cytosine: Synthesis, Structure, and Cytotoxic Activity
This work describes the synthesis of 8‐iodoimidazo[1,2‐c]pyrimidin‐5(6H)‐one 2 from 5‐iodocytosine 1. This compound was subjected to Suzuki cross‐coupling reaction with aryl and heteroarylboronic acids. After optimization, 10 products 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j were obtained in good yields 61‐90%. Cytotoxic activity of all new products was evaluated on seven tumor cell lines including resistant
这项工作描述了从5-碘胞嘧啶1合成8-碘咪唑并[1,2- c ]嘧啶-5(6 H)-one 2。该化合物与芳基和杂芳基硼酸进行了铃木交叉偶联反应。经过优化后,有10个产品3a,3b,3c,3d,3e,3f,3g,3h,3i,3j获得了61-90%的高收率。在包括抗性变体在内的七个肿瘤细胞系和正常人成纤维细胞上评估了所有新产品的细胞毒活性。在3h的情况下,两种衍生物表现出良好的生物活性和良好的治疗指数。

)-one as a novel core of cyclin-dependent kinase 2 inhibitors: Synthesis, activity measurement, docking, and quantum mechanical scoring
We report on the synthesis, activity testing, docking, and quantum mechanical scoring of novel imidazo[1,2‐c]pyrimidin‐5(6H)‐one scaffold for cyclin‐dependent kinase 2 (CDK2) inhibition. A series of 26 compounds substituted with aromatic moieties at position 8 has been tested in in vitro enzyme assays and shown to inhibit CDK2. 2D structure‐activity relationships have ascertained that small substituents
我们报告了新型咪唑并[1,2 - c ]嘧啶-5(6 H)-1支架对细胞周期蛋白依赖性激酶2(CDK2)抑制的合成,活性测试,对接和量子力学评分。在体外酶法中已经测试了一系列在位置8处被芳香族部分取代的26种化合物,并显示出抑制CDK2的作用。二维结构与活性的关系已确定,位置8处的小取代基(最大为萘基或甲氧基苯基的大小)通常会导致单位数微摩尔IC 50较大的取代基(取代的联苯)会降低化合物的活性。使用Glide对接获得的化合物的结合模式在CDK2上显示出最多2个铰链区氢键,并且在抑制剂核心的取向和8个取代基的位置上有所不同。基于半经验量子力学的计分方法确定了可能的有利结合模式,这将有助于未来基于结构的设计以及杂环核取代基的合成优化。总之,我们已经确定了CDK2抑制的新核心,并将进一步探索以增加化合物的效力并监测其对其他蛋白激酶的选择性。
