Study IDST001205
Study TitlePeroxide antimalarial treatment of K13-mutant and -wildtype P. falciparum parasites
Study SummaryRed blood cells (RBCs) infected with trophozoite stage P. falciparum parasites (Cam3.IIR539T or Cam3.IIrev lines) at 4% parasitaemia and 2% haematocrit were treated with 100 nM of DHA, OZ277 or OZ439 for a duration of 1, 3 and 5 h, respectively. The K13-mutant artemisinin resistant parasite line used was Cam3.IIR539T. The K13-wildtype artemisinin sensitive parasite line used was Cam3.IIrev. The Samples treated with vehicle (DMSO) acted as the untreated control.

Sample Preparation:

Sampleprep ID:SP001280
Sampleprep Summary:RBCs infected with Cam3.IIR539T (resistant) or Cam3.IIrev (sensitive) P. falciparum parasites (22-26 h post invasion) were adjusted to 4% parasitaemia and 2% haematocrit and the culture medium refreshed prior to drug addition. Following the drug incubation period, 1E8 cells were pelleted by centrifugation at 1,000 x g for 3 min and the culture medium was removed. Parasite metabolism was quenched by the addition of ice-cold PBS, pelleted again and the supernatant discarded prior to metabolite extraction. Metabolites were extracted from the cell pellet using 150 µL of cold methanol. The extraction solvent containing the internal standard compounds CHAPS (3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate), CAPS (3-(cyclohexylamino)-1-propanesulfonic acid), PIPES (1,4-piperazinediethanesulfonic acid) and TRIS (2-amino-2-(hydroxymethyl)-1,3-propanediol) was directly added to the cell pellet, mixed by pipetting and subjected to automatic vortex mixing for 1 h at 4°C. Following the 1 h incubation, samples were pelleted by centrifugation at 21,100 x g for 10 min, 110 µL of particle free supernatant was transferred to glass LC-MS vials and stored at -80°C until analysis. A 15 µL aliquot of each sample was combined to generate a pooled biological quality control (PBQC) sample.
