Evaluation of potent drug combination strategies in urachal cancer cells. a Dose–response matrices of percent of cell viability resulting from exposure to the indicated drug combinations. Drugs were tested in 6 concentration in a matrix covering all possible combination of the dilutions in triplicate. Cells were exposed to the drugs for 72 h in 2D cell culture. b Curve fitted dose response curves and a table with the IC50 estimates of the single agents and the CI50 combination index values for the drugs at a fixed molar ratio of 1 to 2.5
