Fig. 6From: Actions of sesquiterpene lactones isolated from Moquiniastrum polymorphum subsp. floccosum in MCF7 cell line and their potentiating action on doxorubicinEffects of 2 on drug Combination Index (CI) of MCF7 cell line. The concentrations of 2 (0.5; 2; 3 and 4 μM) were combined with the IC 50 of the chemotherapeutic agents irinotecan a, tamoxifen b, cisplatin 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 effectBack to article page
