PUBCHEM_BIOASSAY: Counterscreen qHTS for Inhibitors of Tau Fibril Formation, Fluorescence Polarization. This assay monitors tau fibrillation by fluorescence polarization (FP) of Alexa 594-labeled K18 P301L, which does not fibrillize readily but incorporates into growing filaments of unlabeled tau.

MMV: Primary screening was performed with each compound at a 30 uM final concentration and in triplicate in sealed 96-well polystyrene microtiter plates. Parasite inocula (100 ul) comprising 20000 parasites/ml were added to each well and grown at 37 degrees C in a humidified atmosphere of 5% CO2 for 72 h. Positive controls consisted of metronidazole at 1 mg/ml. The growth of E. histolytica trophozoites in each well was determined microscopically by measuring the diameters of the confluent cells in drug-containing wells relative to those in the nega- tive-control wells.
MMV: A total of 100ul of inoculum was added to each well (parasite/cell ratio, ~10:1; final volume, 200 ul). Six hours after inoculation, nonadherent parasites were removed, and 100 ul of complete DMEM (1% penicillin-streptomycin, 3% FBS) supplemented with inhibitors at different concentrations (2-fold serial dilutions starting from 30 uM) was added to all except the negative-control wells. Positive controls, consisting of pyrimethamine (PYR) and sulfadiazine (SDZ) (20-mg/ml stocks in DMSO), were tested at a 2mg/ml final concentration. Each test was performed in triplicate.
