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.

喹啉衍
生物,它们有效地抑制或消除疟原虫生命周期中至少一个阶段的活力,并显示出减少诱导目标疟原虫对化合物的抗性的倾向。特别地,这些化合物可以是苯氧
乙氧基喹啉衍
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一种其他衍
生物化合物或其他抗疟疾化合物一起,用于动物或人类受试者。治疗组合物可以被配制成减少受试者中恶性疟原虫感染程度或在疟原虫接触受试者之前使用以减少恶性疟原虫感染的发生或建立可能性的有效单剂量抗疟疾化合物或多剂量抗疟疾化合物。
