  Investigation on the 1,6-naphthyridine motif: discovery and SAR study of 1H-imidazo[4,5-h][1,6]naphthyridin-2(3H)-one-based c-Met kinase inhibitors

  摘要：

  1,6-萘啶结构是药物化学中的一种多价支架，在适当取代时表现出多种生物活性。通过在1,6-萘啶框架中引入一个环脲药效基，并通过对7、8位进行构象约束，所得到的1H-咪唑[4,5-h][1,6]萘啶-2(3H)-酮被确认为一种新的c-Met激酶抑制剂。全面的SAR研究表明，带有末端游离氨基的N-1烷基取代基、N-3位的疏水性取代苯基团以及三环核心对于保持1H-咪唑[4,5-h][1,6]萘啶-2(3H)-酮化合物的有效Met抑制至关重要。进一步在C-5位引入4′-氨甲酰基苯氧基基团显著提高了活性。最佳的c-Met激酶抑制活性由2t所体现，IC50 = 2.6 μM，同时在低微摩尔浓度下对TPR-Met磷酸化和BaF3-TPR-Met细胞增殖表现出有效抑制。

  Repositioning HIV-1 Integrase Inhibitors for Cancer Therapeutics: 1,6-Naphthyridine-7-carboxamide as a Promising Scaffold with Drug-like Properties

  摘要：

  Among a large number of HIV-1 integrase (IN) inhibitors, the 8-hydroxy-[1,6]naphthyridines (i.e., L-870,810) were one of the promising class of antiretroviral drugs developed by Merck Laboratories. In spite of its remarkable potency and efficacy, unfortunately upon completion of phase I clinical studies, development of L-870,810 was halted. Because of its desirable pharmacological and pharmaceutical properties we were intrigued to design novel analogues of L-870,810 with goals to (1) improve upon limitations of naphthyridine-7-carboxamides as antiviral agents and (2) to reposition their use as innovative cytotoxic agents for cancer therapeutics. Herein, we report on the design and synthesis of a series of 1,6-naphthyridine-7-carboxamides with various substitutions at the 5- and 8-positions. All the new 5-substituted-8-hydroxy-[1,6]naphthyridines were potent IN inhibitors and the 5-substituted-8-amino-[1,6]naphthyridines were significantly cytotoxic. Further optimization of the 5,8-disubstituted-[1,6]naphthyridines with structural variation on 7-carboxamide delivered novel compounds with significant cytotoxicity in a panel of cancer cell lines and effective inhibition against select oncogenic kinases.

  tolerated in vivo. Investigation of the mode of action (MoA) demonstrated that activity was driven by sequestration of divalent metal cations, a mechanism which was likely to drive the poor tolerability. This highlights the importance of investigating MoA and pharmacokinetics at an early stage for phenotypically active series.

  内脏利什曼病 (VL) 是一种寄生虫感染，每年导致大约 26 000-65 000 人死亡。可用的治疗方法受到毒性、疗效可变和不合适的剂量选择等问题的阻碍。迫切需要新的治疗方法，这导致了被忽视疾病药物计划(DND i )、葛兰素史克 (GSK) 和邓迪大学之间的合作。8-羟基萘啶被确定为起点，早期化合物在 VL 小鼠模型中表现出较弱的功效，但受到葡萄糖醛酸化的阻碍。解决这个问题的努力导致开发了具有改善体外特征的化合物，但这些化合物在体内耐受性差. 对作用方式 (MoA) 的研究表明，活性是由二价金属阳离子的螯合驱动的，这种机制可能导致耐受性差。这突出了在早期研究表型活性系列的 MoA 和药代动力学的重要性。

  The 1,6-naphthyridine motif is a multivalent scaffold in medicinal chemistry presenting various bioactivities when properly substituted. By incorporating a cyclic urea pharmacophore into the 1,6-naphthyridine framework through conformationally constraining the 7,8-positions, the resulting 1H-imidazo[4,5-h][1,6]naphthyridin-2(3H)-one was identified as a new class of c-Met kinase inhibitor. A comprehensive SAR study indicated that an N-1 alkyl substituent bearing a terminal free amino group, a hydrophobic substituted benzyl group at the N-3 position and the tricyclic core were essential for retaining effective Met inhibition of the 1H-imidazo[4,5-h][1,6]naphthyridin-2(3H)-one chemotype. Further introduction of a 4′-carboxamide phenoxy group at the C-5 position significantly improved the potency. The best c-Met kinase inhibitory activity was exemplified by 2t with an IC50 = 2.6 μM, which also displayed effective inhibition against TPR-Met phosphorylation and the proliferation of the BaF3-TPR-Met cells at low micromolar concentrations.
