In vitro(体外研究)
In addition to Pim, SGI-1776 also potently targets FLT3 (IC50 = 44nM). Treatment of AML cells with SGI-1776 results in a concentration-dependent induction of apoptosis. Importantly, SGI-1776 is also cytotoxic in AML primary cells, irrespective of FLT3 mutation status and results in Mcl-1 protein decline. Treatment of CLL cells with SGI-1776 results in a concentration-dependent induction of apoptosis. SGI-1776 induces apoptosis in CLL and that the mechanism involves Mcl-1 reduction. Apoptosis induction coupled with the inhibition of RNA synthesis is observed in CLL cells treated with SGI-1776. SGI-1776 exhibites cytotoxic activity in vitro with a median relative IC50 of 3.1 mM. SGI-1776 induces tumor growth inhibition meeting criteria for intermediate EFS T/C activity in 1 of 39 evaluable models. In contrast, SGI-1776 induces complete responses of subcutaneous MV4;11.
In vivo(体内研究)
Consistent with cell line data, xenograft model studies with mice bearing MV-4-11 tumors shows efficacy with SGI-1776. SGI-1776 has shown preclinical activity against leukemia and solid tumor cell line models with IC50 values of 0.005–11.68 mM. SGI-1776 induces significant differences in EFS distribution in vivo in 9 of 31 solid tumor xenografts and in 1 of 8 of the evaluable ALL xenografts.
