  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.

  Copper-Catalyzed C–N Coupling in the Synthesis of Integrase Inhibitors of Immunodeficiency Viruses

  摘要：

  This contribution describes the total synthesis of a complex macrocyclic integrase inhibitor, a key enzyme involved in the infection process of various immunodeficiency viruses. The key transformation of the synthetic strategy was the selective C-N coupling of a sulfonamide to a heteroaryl bromide in the presence of potentially competing amide and carbamate functionalities. The transformation was accomplished with CuI catalysis using bypiridine as the ligand in the presence of base and enabled a convergent approach to the target molecule.

• 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

  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.

  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。
