Hierarchical analysis of cell lines and anti-cancer drugs. The cell lines and anti-cancer drugs were grouped based on the growth suppression data (Additional file 3: Table S3) using hierarchical cluster analysis. The cells were treated with 10 µM of each drug and analyzed for viability, which was calculated after comparison with the control and presented as a heat map. The names of the cell lines and anti-cancer drugs are color-coded
