Description

作为抗蠕虫药的新的磺酰基氨基苯甲酰胺化合物
本发明涉及新的磺酰基氨基苯甲酰胺化合物,及其在控制温血动物体内寄生虫例如恶丝虫(heartworms)中的用途。
犬恶丝虫(Dirofilaria immitis)是通过蚊子叮咬从宿主向宿主传播的寄生线虫。终宿主是狗,但是其还可以感染猫和其他温血动物。尽管通常称作“恶丝虫”,成年蠕虫实际多半寄生于肺动脉系统(肺动脉),对动物健康的主要影响是损害肺导管和组织。偶发地,成年恶丝虫迁移至重度感染的右心脏,并且甚至大静脉。恶丝虫感染可引起宿主的严重疾病。
恶丝虫感染可用基于砒霜的化合物对抗;治疗是耗时、麻烦的,并且经常只是部分成功的。因此,主要关注点是预防恶丝虫感染。目前,仅通过全年定期向狗、猫和其他温血动物施用大环内酯类例如伊维菌素、莫昔克丁或米尔倍霉素肟,实现恶丝虫预防。不幸地,在USA的一些地区,已观察到犬恶丝虫对大环内酯类即将出现的抵抗。因此,亟需发现新类型化合物,其通过预防或通过直接杀死不同阶段的恶丝虫,可有效控制恶丝虫感染。现在,已令人吃惊地发现一组新的磺酰基氨基苯甲酰胺化合物,其可有效控制温血动物的体内寄生虫,包括有效控制恶丝虫。
