The present invention relates to novel 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives, processes for producing said derivatives, intermediate compounds to produce said derivatives, processes to produce said intermediate compounds, and compositions containing said derivatives with potent diuretic activity that can be used for treating and/or preventing hypertension, oedema and/or for removing ascites. The present invention is based on the selection of 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives, namely O-sulfate, O-mesylate, O-methylphosphate and O-carboxymethyl ether, especially O-sulfate of 4-oxime. The compounds of the present invention containing these substituents have potent hypotensive, anti-oedematous and diuretic effect as well as an activity to remove ascites and are extremely useful for the treatment of diseases and disorders mentioned above.

The 4-aminoquinoline moiety is widely present in various bioactive compounds and marketed drugs, while the preparation of this target structure relies heavily on the amination of 4-chloroquinolines. Herein, an atom and step economic procedure was developed based on an aerobic dehydrogenative aromatization strategy. Unlike the well-known palladium-catalyzed dehydrogenative aromatization of cyclohexanones
4-氨基喹啉部分广泛存在于各种生物活性化合物和市售药物中,而该目标结构的制备很大程度上依赖于4-氯喹啉的胺化。在此,基于有氧脱氢芳构化策略开发了原子和步骤经济程序。与众所周知的钯催化环己酮与胺的脱氢芳构化不同,协同 Pd/Cu 催化对于 2,3-二氢喹啉-4(1 H )-one 类型的底物至关重要。在优化条件下,一系列芳香族/脂肪族胺和2,3-二氢喹啉-4(1H ) -酮偶联,以中等到高收率得到相应的4-氨基喹啉产物,并应用当前的方法还展示了上市药物的制备和后期多样化。

Novel chroman and tetrahydroquinoline ureas were synthesized and evaluated for their activity as TRPV1 antagonists. It was found that aryl substituents on the 7- or 8-position of both bicyclic scaffolds imparted the best in vitro potency at TRPV1. The most potent chroman ureas were assessed in chronic and acute pain models, and compounds with the ability to cross the blood-brain barrier were shown to be highly efficacious. The tetrahydroquinoline ureas were found to be potent CYP3A4 inhibitors, but replacement of bulky substituents at the nitrogen atom of the tetrahydroisoquinoline moiety with small groups such as methyl can minimize the inhibition.
