New antiprotozoals active against Philasterides dicentrarchi, the causative agent of scuticociliatosis in farmed turbot and Black Sea bass-bream, have been synthesised and tested. The most active compounds posses a piperazine ring, generally N-bonded to the heterocycle, and are the 1,8-naphthyridines, 2f and 5o, the pyridothienopyrimidine (7), and the pyridothienotriazines, 8, 9, 12d, 12f, 12h, 12m
合成和测试了新的抗原生动物动物,它们对养殖费氏鱼和黑海鲈鱼中的刀oci病的致病因子Philasterides dicentrarchi具有活性。活性最高的化合物通常具有N键合至杂环的哌嗪环,分别为1,8-萘啶2f和5o,吡啶并吡啶并嘧啶(7)和吡啶并噻吩并三嗪8、9、12d,12f,12h, 12m和12k。吡啶并三嗪(12k)具有与众所周知的抗寄生虫药niclosamide和oxyclozanide相同的活性(致死剂量,LD = 0.8 / 1.5 mg L(-1))。
