were prepared and evaluated for anticoccidial activity. Of these compounds, 2-, 4- and 5-nitropyridine-3-sulfonamides and pyridine-2- and -3-sulfonamide N-oxides were found to be active against Eimeria tenella. Thus, the relative positions, ortho or meta, of the substituents in nitropyridine-3-sulfonamides and pyridinesulfonamide N-oxides are important for anticoccidial activity. N-Substituted analogues
制备了八种硝基吡啶磺酰胺和吡啶磺酰胺N-氧化物作为它们的生物等排体,并评估了抗球虫活性。在这些化合物中,发现2-,4-和5-硝基吡啶-3-磺酰胺和吡啶-2-和-3-磺酰胺N-氧化物具有对抗艾美尔球虫的活性。因此,硝基吡啶-3-磺酰胺和吡啶磺酰胺N-氧化物中取代基的相对或间位对于抗球虫活性很重要。还制备了5-硝基吡啶-3-磺酰胺的N-取代的类似物,并用磺酰胺及其低级N-烷基衍生物获得了最佳的抗球虫活性。检查了5-硝基吡啶-3-磺酰胺的作用方式,发现其在子孢子和精神分裂的第一阶段均具有活性。
