mortality. Resistance to current anticoccidials has prompted the search for new therapeutic agents with potent in vitro and in vivo activity against Eimeria. Antiparasitic activity is due to inhibition of a parasite specific cGMP-dependent protein kinase (PKG). In this study, we present the synthesis and biological activity of imidazo[1,2-a]pyridine anticoccidial agents. From this series, several compounds
球虫病是家禽业发病率和死亡率的主要原因。艾美球虫属的原生动物寄生虫侵入禽类宿主的肠壁,引起组织病理学,体重增加不良,在某些情况下甚至导致死亡。对当前抗球虫药的耐药性促使人们寻找对艾美尔球虫具有强大的体外和体内活性的新治疗剂。抗寄生虫活性是由于抑制了寄生虫特异性cGMP依赖性蛋白激酶(PKG)。在这项研究中,我们介绍了咪唑并[1,2-a]吡啶抗球虫剂的合成和生物活性。从该系列中,几种化合物显示出亚纳摩尔体外活性和商业水平的体内活性。但是,这些化合物的潜在遗传毒性使它们无法进一步开发。
