  Discovery of Potent, Orally Bioavailable Phthalazinone Bradykinin B1 Receptor Antagonists

  摘要：

  The bradykinin B1 receptor is rapidly induced upon tissue injury and inflammation, stimulating the production of inflammatory mediators resulting in plasma extravasation, leukocyte trafficking, edema, and pain. We have previously reported on sulfonamide and sulfone-based B1 antagonists containing a privileged bicyclic amine moiety leading to potent series of 2-oxopiperazines. The suboptimal pharmacokinetics and physicochemical properties of the oxopiperazine sulfonamides led us to seek B1 antagonists with improved druglike properties. Using a pharmacophore model containing a bicyclic amine as anchor, we designed a series of amide antagonists with targeted physicochemical properties. This approach led to a novel series of potent phthalazinone B1 antagonists, where we successfully replaced a sulfonamide acceptor with a cyclic carbonyl unit. SAR studies revealed compounds with subnanomolar B1 binding affinity. These compounds demonstrate excellent cross-species PK properties with high oral bioavailability and potent activity in a rabbit biochemical challenge pharmacodynamic study.

  3-(N-Substituted) 4(1H)-quinolinones were synthesized using the copper-catalyzed Ullmann C–N bond forming strategy in moderate to quantitative yields. Starting from 3-halo-4(1H)-quinolones, various nucleophiles including amides, lactams, sulfonamides and NH-containing azoles have been used successfully. In all cases, the reactions take place rapidly in toluene and proceed by using copper powder as

  使用铜催化的Ullmann C–N键形成策略以中等至定量的产率合成了3-（N-取代的）4（1 H）-喹啉酮。从3-卤代-4（1 H）-喹诺酮类化合物开始，已成功使用了各种亲核试剂，包括酰胺，内酰胺，磺酰胺和含NH的唑。在所有情况下，反应都在甲苯中迅速进行，并通过使用铜粉作为催化剂，DMEDA作为配体和K 2 CO 3作为碱进行。此外，在我们的Cu / DMEDA催化剂体系下，其他相关杂环，例如3-溴喹啉-2（1 H）-ones，3-溴香豆素和3,5-二溴-2-吡啶酮显示出与各种亲核试剂的良好或非常高的反应性。 。

  synthesis of 4-chloro/bromo/iodopyrazoles from hydrazines, acetylacetones and sodium halides under chemical oxidant- and external electrolyte-free conditions has been developed. Sodium halides played a dual role as a halogenation reagent and a supporting electrolyte. Mechanism studies revealed that the bromination reaction proceeded via an ionic pathway, whereas both chlorination and iodination proceeded
