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.

Antimalarial activity of 1,2,3,4-tetrahydroacridin-9(10H)-ones (THAs) has been known since the 1940s and has garnered more attention with the development of the acridinedione floxacrine (1) in the 1970s and analogues thereof such as WR 243251 (2a) in the 1990s. These compounds failed just prior to clinical development because of suboptimal activity, poor solubility, and rapid induction of parasite resistance. Moreover, detailed structure-activity relationship (SAR) studies of the THA core scaffold were lacking and SPR studies were nonexistent. To improve upon initial findings, several series of 1,2,3,4-tetrahydroacridin-9(10H)-ones were synthesized and tested in a systematic fashion, examining each compound for antimalarial activity, solubility, and permeability. Furthermore, a select set of compounds was chosen for microsomal stability testing to identify physicochemical liabilities of the THA scaffold. Several potent compounds (EC50 < 100 nM) were identified to be active against the clinically relevant isolates W2 and TM90-C2B while possessing good physicochemical properties and little to no cross-resistance.
