The present disclosure provides N-hydroxylamino-barbituric acid compounds of formulae (1)- (4), pharmaceutical compositions and kits comprising them, and methods of using such compounds or pharmaceutical compositions. The present disclosure provides methods of using such compounds or pharmaceutical compositions for treating heart failure.
The present invention provides a novel class of modified pyrimidine compounds and compositions and methods of using the compounds as glucocorticoid receptor modulators.
One pot cyclocondensation reaction of barbituric/thiobarbituricacid with aromatic aldehydes and p-phenylenediamine/2,6-diaminopyridine by refluxing in glacial acetic acid afforded novel bis(pyrimido[5,4-c]quinoline-2,4(1H,3H)-diones)/pyrido bis(pyrimido[5,4-c]quinoline-2,4(1H,3H)-diones. All the synthesized compounds were screened for their antioxidant activities using FRAP and DPPH methods. Compounds
通过在冰醋酸中回流,使巴比妥/硫代巴比妥酸与芳族醛和对苯二胺/ 2,6-二氨基吡啶进行一锅环缩合反应,得到新的双(嘧啶并[5,4 - c ]喹啉-2,4(1 H,3)H)-二酮)/吡啶双(嘧啶[5,4 - c ]喹啉-2,4(1 H,3 H)-二酮。所有合成的化合物均采用FRAP和DPPH方法筛选其抗氧化活性。氯取代基显示出相对良好的抗氧化性能。

5-substituted benzylbarbituric acids has been determined in 50% ethanol/water and they were found to be more acidic than barbituric acid. The pKas of these derivatives obey Hammett's equation indicating that their acidity is affected by substituents in the same manner as the benzoic acid ionization constants. A synthesis of these acids is described.
已在50%的乙醇/水中测定了5-苄基巴比妥酸和一系列5-取代的苄基巴比妥酸的酸度,发现它们比巴比妥酸更酸性。这些衍生物的p K a s服从哈米特方程,表明它们的酸度受取代基影响的方式与苯甲酸电离常数相同。描述了这些酸的合成。
