ZLc002 synergizes with paclitaxel in 4T1 cells to reduce breast cancer tumor cell line viability. Dose–response matrix for the effect of (a) ZLc002 and (b) paclitaxel in 4T1 cells. Abs EC50, absolute EC50 > 50 µM, reflects little or no inhibition of 4T1 tumor cell viability by ZLc002; Abs EC50, absolute EC50 = 33.5 nM, reflects efficacy of paclitaxel in reducing 4T1 tumor cell viability by 50% of maximum. (c–d) Single-agent and combination responses determined by an MTT viability assay in 4T1 cells. The landscape of the combination responses for ZLc002 and paclitaxel based on the (e) Bliss model, (f) Loewe model, and (g) highest single agent (HSA) model. Each model supports synergism of the combination of ZLc002 with paclitaxel in reducing tumor cell line viability. (n = 7 experiments). HSA: highest single agent.
