Effects of 1 on the Combination Index (CI) of drugs in MCF7 cell line. Compound 1 concentrations (40; 100; 200; 300 and 400 μM) were combined with the IC50 of the chemotherapeutic agents irinotecan a, tamoxifen b, cisplatin c, 5-Fluouracyl d and doxorubicin e. CI and the normalized isobolograms was calculated using the CompuSyn software, where: CI <1 synergism; CI = 1 additive effect; CI > 1 antagonistic effect
