  1. Drug synergy scores were calculated by three different ways, combination index (CI) by Loewe additivity model, sum of excess of bliss (EOB) by Bliss independence model, and delta drug sensitivity score (ΔDSS) by area under curve method. Synergistic interaction gave CI less than 1, EOB more than zero, and ΔDSS more than zero. Drug combinations which showed synergism by all three methods were indicated by “ a ”. Those which showed synergism by EOB and ΔDSS were indicated by “b”. Those which showed synergism by CI and ΔDSS were indicated by “c”. 12 drug names: INK128 (INK), paclitaxel (PAC), vinblastine (VIN), 17AAG (AAG), AUY922 (AUY), PS341 (PS), MG132 (MG), etoposide (ETO), gemcitabine (GEM), panobinostat (PAN). Six drug classes: mTOR inhibitor (mTOR), microtubule dynamics inhibitor (MT), HSP90 inhibitor (HSP), proteasome inhibitor (PROT), DNA synthesis inhibitor (DNA), histone deacetylase inhibitor (HDAC)
