Artefenomel and DSM265 are two new compounds that have been shown to be well tolerated and effective when administered as monotherapy malaria treatment. This study aimed to determine the safety, pharmacokinetics, and pharmacodynamics of artefenomel and DSM265 administered in combination to healthy subjects in a volunteer infection study using the Plasmodium falciparum-induced blood-stage malaria model. Thirteen subjects were inoculated with parasite-infected erythrocytes on day 0 and received a single oral dose of artefenomel and DSM265 on day 7.

The series of des-Cl (unsubstituted) and m-Cl phenyl analogues of PYR with various flexible 6-substituents were synthesized and studied for the binding affinities with highly resistant quadruple mutant (QM) DHFR. The derivatives carrying 4 atoms linker with a terminal carboxyl substituted on the aromatic ring exhibited good inhibition to the QM enzyme and also showed effective antimalarial activities against resistant P. falciparum bearing the mutant enzymes with relatively low cytotoxicity to mammalian cells.

The scientific community worldwide has realized that malaria elimination will not be possible without development of safe and effective transmission-blocking interventions. Primaquine, the only WHO recommended transmission-blocking drug, is not extensively utilized because of the toxicity issues in G6PD deficient individuals.

Artemisinin-ferrocene conjugates incorporating a 1,2-disubstituted ferrocene analogous to that embedded in ferroquine but attached via a piperazine linker to C10 of the artemisinin were prepared from the piperazine artemisinin derivative, and activities were evaluated against asexual blood stages of chloroquine (CQ) sensitive NF54 and CQ resistant K1 and W2 strains of Plasmodium falciparum (Pf).
