MLN0905 possesses reasonable selectivity against a panel of 359 kinases. MLN0905 inhibits a panel of lymphoma cells viability with IC50 of 3 – 24 nM.
In vivo
Nude mice bearing HT-29 xenografts administered with MLN0905 (6.25 mg/Kg - 50 mg/Kg, p.o.) shows dose-dependent pharmacodynamic responses (48 hours after treatment). OCI LY-19-Luc tumor bearing mice administered with MLN0905 (3.12 mg/Kg – 6.25 mg/Kg, p.o.) shows significant pharmacodynamic responses amd peaks at 8 hours after treatment. MLN0905 shows antitumor efficacy in treatment with OCI LY-19-Luc xenografts bearing scid mice for 21 days. The T/C of 6.25 mg/Kg daily group is 0.15.
