体外研究
MLN0905 (compound 12c) exhibits potent activities with an EC50 of 33 ± 21 nM for Cdc25C. MLN0905 shows inhibitory effects on HT29, HCT116, H460, and A375 cell lines, with LD50s of 22, 56, 89, and 34 nM. MLN0905 (125 nM) yields strong mitotic arrest and monopolar spindle formation in HT-29 cells, and these effects are associated with PLK1 inhibition. MLN0905 suppresses lymphoma cell lines with IC50 values ranging from 3 to 24 nM.
体内研究
MLN0905 (50 mg/kg, p.o.) shows a higher sustained PD response as it impressively generates a robust PD response up to 72 h in nude mice bearing HT29 xenograft tumors. MLN0905 (6.25, 12.5, 25, 50 mg/kg, p.o.) exhibits significant antitumor activities in mice bearing HT29 xenograft tumors. MLN0905 has marked antitumor effects in a subcutaneous OCI LY-19-Luc lymphoma xenograft model, and the treatment are as follows: 3.12 mg/kg daily, 6.25 mg/kg daily, 10 mg/kg QD×3/wk, and 14.5 mg/kg QD×3/wk. MLN0905 (1.6, 3.12, and 6.25 mg/kg, p.o.) also induces a significant antitumor response in mice bearing disseminated (human) OCI LY-19-Luc lymphoma disease. MLN0905 (6, 8, 10, 12.5, and 14.5 mg/kg, p.o.) causes a significant antitumor response in a primary human lymphoma model (PHTX-22L). Furthermore, MLN0905 synergizes with rituximab in a disseminated OCI LY-19-Luc lymphoma model.
