  Design and Synthesis of Poly ADP-ribose Polymerase-1 Inhibitors. 2. Biological Evaluation of Aza-5[H]-phenanthridin-6-ones as Potent, Aqueous-Soluble Compounds for the Treatment of Ischemic Injuries

  摘要：

  A series of aza-5[H]-phenanthridin-6-ones were synthesized and evaluated as inhibitors of poly ADP-ribose polymerase-1 (PARP-1). Inhibitory potency of the unsubstituted aza-5[H]-phenanthridin-6-ones (i.e., benzonaphyhyridones) was dependent on the position of the nitrogen atom within the core structure. The A ring nitrogen analogues (7-, 8-, and 10-aza-5[H]-phenanthridin-6-ones) were an order of magnitude less potent than C ring nitrogen analogues (1-, 2-, 3-, and 4-aza-5[H]-phenanthridin-6-ones). Preliminary stroke results from 1- and 2-aza-5[H]-phenanthridin-6-one prompted structure-activity relationships to be established for several 2- and 3-substituted 1-aza-5[H]-phenanthridin-6-ones. The 2-substituted 1-aza-5[H]-phenanthridin-6-ones were designed to improve the solubility and pharmacokinetic profiles for this series of PARP-1 inhibitors. Most importantly, three compounds from this series demonstrated statistically significant protective effects in rat models of stroke and heart ischemia.

  satisfactory system being palladium(II) acetate in NN-dimethylacetamide (DMA) with sodium carbonate as base) has been examined as a route to some heterocyclic systems. Whereas dehydrogenative cyclisation processes require stoichiometric amounts of palladium(II) reagent, the present procedure involves only catalytic amounts (0.1 molar proportion, or less), of palladium compound.

  Synthesis of substituted phenanthridinones and dibenzoazepinones has been realized from 2-halo-benzamides in the presence of potassium tert-butoxide and a catalytic amount of 1,10-phenanthroline or AIBN. This new carbon–carbon bond forming reaction gives direct access to various biaryl lactams containing six- and seven-membered rings chemoselectively. Carbon–carbon coupling seems to proceed by the generation

  3a, and 4 afforded photocyclized products, benzo[c]naphthyridinones (6-9 and 16), in high yield, whereas the bromo analogues 1b, 2b, and 3b produced extensively photoreduced products, N-pyridinylbenzamides (1c, 10, and 11), with minor photocyclized product. Since the photocyclization reaction of 2-chloro-N-pyridinylbenzamide is retarded by the presence of oxygen and sensitized by the presence of a

  研究了2-卤代-N-吡啶基苯甲酰胺（图1中的1-4）的光化学行为。2-氯-N-吡啶基苯甲酰胺1a，2a，3a和4的光反应可提供高收率的光环化产物苯并[c]萘啶酮（6-9和16），而溴代类似物1b，2b和3b产生大量光还原的产品，N-吡啶基苯甲酰胺（1c，10和11），以及次要的光环化产品。由于2-氯-N-吡啶基苯甲酰胺的光环化反应由于氧气的存在而被阻滞，并且由于三重态敏化剂，丙酮或苯乙酮的存在而被敏化，因此氯类似物的三重态处于反应中。由于在2-氯-N-吡啶基苯甲酰胺的激光闪光光解中发现了几种自由基中间体，尤其是氯自由基的n-络合物，提出了苯基自由基与氯自由基的n-络合辅助的分子内环化机理，以用于环化反应：由1a激发而形成的氯代类似物（1a）的三重态（78 kcal / mol）经历均相裂解C-Cl键以产生苯基和氯基；当氯自由基通过n络合物保持相邻的吡啶基环时，苯基与吡啶基环的分子内芳基化反应产生共轭的2
