NOVARTIS: Inhibition Frequency Index (IFI) - the number of HTS assays where a compound showed > 50% inhibition/induction, expressed as a percentage of the number of assays in which the compound was tested.
NOVARTIS: Antimalarial liver stage activity measured as a greater than 50% reduction in Plasmodium yoelii schizont area in HepG2-A16-CD81 cells at 10uM compound concentration, determined by immuno-fluorescence.
MMV: Toxicity @ 2.5 uM to newly transformed Schistosoma mansoni somules after 24 h on a scale of 0 (none) - 4 (most) as judged visually: includes short descriptors of effects (PMID:19597541). Caffrey group UCSF.
MMV: Toxicity @ 2.5 uM to newly transformed Schistosoma mansoni somules after 48 h on a scale of 0 (none) - 4 (most) as judged visually: includes short descriptors of effects (PMID:19597541). Caffrey group UCSF.
MMV: Toxicity @ 2.5 uM to newly transformed Schistosoma mansoni somules after 72 h on a scale of 0 (none) - 4 (most) as judged visually: includes short descriptors of effects (PMID:19597541). Caffrey group UCSF.
MMV: Compounds (1uM) were screened in a 72hr growth assay monitored by flow cytometry both in the presence and absence of supplemental isopentenyl pyrophosphate (IPP) 200uM. Compounds which fail to show anti-malarial activity when chemically rescued by IPP are therefore specific to the apicoplast. The values are expressed as the ratio of the corresponding activity with and without IPP, respectively.
MMV: Cryptosporidium parvum oocysts (Iowa Strain) were prepared for use by treatment with 10 mM HCl (37 degrees C, 10 min) followed by 2 mM sodium taurocholate in phosphate-buffered saline (PBS) with Ca2+ and Mg2+ (16 degrees C, 10 min) in order to stimulate excystation. The high-throughput screen was carried out by inoculating >90% confluent human ileocecal adenocarcinoma (HCT-8) cells (ATCC) with ~5.5 x 10^3 primed oocysts per well. Experimental compounds or DMSO (vehicle) were added three hours after infection, and cells were incubated for 48 hours.
