Some novel pyrazole-NO hybrid molecules 5a–e, 6, 8 and 10 were prepared through binding of the pyrazole-3-carboxylic acid derivatives with nitric oxide donor moiety like oxime or nitrate ester. The prepared compounds were evaluated for nitric oxide release, antibacterial and anti-inflammatory activities. The organic nitrate 10 exhibited the highest percentage of NO release using Griess diazotization
一些新的吡唑-NO杂交分子5A - ë,6,8和10是通过与像肟或硝酸酯一氧化氮供体部分的吡唑-3-羧酸衍生物的结合制备。评价所制备的化合物的一氧化氮释放,抗菌和抗炎活性。使用Griess重氮化方法,有机硝酸盐10表现出最高的NO释放百分比。某些制备的化合物对大肠杆菌C-600,铜绿假单胞菌,枯草芽孢杆菌和金黄色葡萄球菌具有显着的抗菌活性。NCTC 6571与环丙沙星相比。与角叉菜胶诱导的爪水肿方法相比,与吲哚美辛相比,大多数测试化合物显示出显着的抗炎活性。通常,化合物2对硝酸酯或肟杂化物的结构修饰显示出比其相应的起始中间体更好的抗炎性和更少的致溃疡性。
