Provided are 4(1H)-quinolone derivatives effective in inhibiting or eliminating the viability of at least one of the stages in the life-cycle of the malarial parasite, and to show a reduced propensity to induce resistance to the compound by the target parasite. In particular, the compounds can be derivatives of phenoxyethoxy-quinolones, and including, but not only, 7-(2-phenoxyethoxy)quinolin derivatives. These compounds may be administered by themselves, with at least one other derivative compound, or with other antimalarial compounds, to an animal or human subject. The therapeutic compositions can be and formulated to reduce the extent of a
Plasmodium
infection in the recipient subject, or to reduce the likelihood of the onset or establishment of a
Plasmodium
infection if administered prior to the parasite contacting the subject. The therapeutic compositions can be formulated to provide an effective single dose amount of an antimalarial compound or multiple doses for administering over a period of time.
提供了4(1H)-喹啉酮衍生物,能有效抑制或消除疟原虫生命周期中至少一个阶段的生存能力,并且显示出减少目标寄生虫对化合物产生抗药性的倾向。具体来说,这些化合物可以是苯氧乙氧基喹啉酮的衍生物,包括但不限于7-(2-苯氧乙氧基)喹啉衍生物。这些化合物可以单独或与至少另一种衍生物化合物或其他抗疟疾化合物一起,向动物或人类受试者施用。治疗组合物可以配制成减少受试者体内疟原虫感染程度的程度,或者在寄生虫接触受试者之前施用,以减少疟原虫感染的可能性。治疗组合物可以配制成提供有效的单剂量抗疟疾化合物或多剂量,以在一段时间内施用。
