In vitro effect of AS602868 combined with SN-38 on cell viability. (A, B) HT-29 cells, SW-480, and SW-620 cells were incubated for 5 days with AS602868, SN-38, or both compounds simultaneously. (C) HT-29 cells were incubated for 5 days with 5-FU, etoposide, or oxaliplatin±AS602868 for 5 days. Cytotoxicity was evaluated using the MTT assay. Data are expressed as mean±s.d. of quadruplicates of one representative experiment out of 8 (A), 3 (B), and 3 (C). * indicates detection of the synergistic effect of AS602868 and SN-38, 5-FU, etoposide, or oxaliplatin on cell viability by using the non-constant ratio isobologram method.
