In silico discovery of substituted pyrido[2,3-d]pyrimidines and pentamidine-like compounds with biological activity in myotonic dystrophy models

Quantification of the number of foci present after treatment with compounds 1–3 and 2–5.
(A) Quantification of foci per cell from the analysis of a minimum of 1000 DM1 fibroblast nuclei in a range of four log dilutions starting at 40 μM for 2–5 and 100 μM for 1–3. The results were normalized to DM1 cells treated with 1% DMSO (marked as a red line). (B) Representative fluorescence in situ hybridization (FISH) images showing foci in DM1 fibroblasts after 48 h treatment with a range of four log dilutions starting at 40 μM for 2–5 and 100 μM for 1–3. 1% DMSO and 4 μM ChA3 were used as a negative and positive control, respectively. Nuclei were stained with Hoechst 33342 (blue) and rCUGexp RNA foci were detected with a Cy3-labelled probe (red). Images included 2x enlargement of selected nucleus.
