Analyses of the disaggregation
capacities of compounds 4a–d and 6a–d under
conditions of general protein aggregation. (A) Numbers and (B) average
areas of green-fluorescing foci of protein aggregates per cell. Control
and NTB-exposed cells were grown in the presence of 0.5% EtOH (compound
vehicle). Data are presented as mean ± SD (n = 4–10, average of a total of ∼4700 cells analyzed
per condition). Significance was determined using the unpaired Student’s t test: (+) for comparison between positive (NTB) and negative
(C) control conditions and (*) for comparison between NTB and NTB
+ compounds. +/*, p < 0.05; ++/**, p < 0.01; +++/***, p < 0.001; ++++/****, p < 0.0001. (C) Micrographs of representative cells of
compounds 4c and 6c. Aggregates are in green
(HSP27:GFP fusion protein) and cell nuclei in blue (DAPI).
