Study ID | ST001202 |
Study Title | Peroxide antimalarial treatment timecourse on ring-stage P. falciparum parasites |
Study Summary | Red blood cells (RBCs) infected with ring stage P. falciparum parasites (3D7 strain) at 10% parasitaemia and 2% haematocrit were treated with OZ277 (1 uM), OZ439 (1 uM), DHA (300 nM) or vehicle (0.03% DMSO). This was a 5-timepoint study, with samples taken 0, 1.5, 3, 6 and 9 h after drug or vehicle addition. Samples treated with vehicle acted as the untreated control. Samples from drug treated uninfected RBCs were also taken to ensure the observed drug effects were parasite specific. |

Sample Preparation:
Sampleprep ID: | SP001277 |
Sampleprep Summary: | Infected RBCs were adjusted to 10% parasitaemia and 2% haematocrit and the culture medium refreshed prior to drug addition. Following the drug incubation period, 2E8 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 200 µL of cold chloroform/methanol/water (1:3:1). 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. |
