SGI-1776 (0.1-10 µM; 24 hours) selectively reduces Mcl-1 protein levels in MV-4-11, MOLM-13, and OCI-AML-3 AML cell lines without altering Bcl-2, Bcl-xL, Bak, or Bax[2].
SGI-1776 reduces the viability and clonogenic survival of 9 hAML cell lines, inhibits proliferation and induces apoptosis, while decreasing Bad phosphorylation and increasing p27 expression[7].
SGI-1776 (1-10 μM; 24 h) induces apoptosis in primary AML cells, with an average increase of 5-19%[8].
SGI-1776 (2.5-5 μM; 72 h) induces early apoptosis in SACC-83 and SACC-LM cells in a dose-dependent manner[3].

SGI-1776 (5-10 µM; 8 days of differentiation) reduces triglyceride content in differentiating 3T3-L1 adipocytes, with the greatest reduction at 10 µM and activity at 5 µM[1].
SGI-1776 (5-10 µM; 8-day differentiation) does not significantly reduce 3T3-L1 adipocyte viability at 5 µM after 8 days, whereas 10 µM causes a slight decrease[1].
SGI-1776 (5 µM; days 0-8) inhibits 3T3-L1 adipogenesis mainly when present during the early differentiation stage, and incubation on days 0-8 produces the highest inhibition rate[1].

In Vivo
SGI-1776 (200 mg/kg/dose; oral; daily × 5 per week) shows in vivo activity in ALL xenografts, reducing tumor proliferation compared with untreated mice[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:NOD-SCID (female)[2]
-
Dosage:50 mg/kg (daily 5 days/week for 3 weeks); 75 mg/kg (daily 5 days/week for 3 weeks); 100 mg/kg (twice weekly for 3 weeks); 200 mg/kg (twice weekly for 3 weeks)
-
Administration:p.o.; daily 5 days/week for 3 weeks (50, 75 mg/kg); twice weekly for 3 weeks (100, 200 mg/kg)
-
Result:In MV-4-11 xenografts, oral SGI-1776 produced potent and sustained antitumor activity.
Tumors in the 75 mg/kg and 200 mg/kg groups disappeared or became almost impalpable within 1 week after administration.
On day 22, 8 of 9 mice given 75 mg/kg SGI-1776 and all 10 mice given 200 mg/kg experienced complete regression; 3 mice in the 75 mg/kg group and 1 mouse in the 200 mg/kg group experienced minor regrowth by the end of the observation period.
Administration of 50 mg/kg SGI-1776 on a daily schedule or 100 mg/kg on a twice-weekly schedule resulted in some antitumor effect; no regressions were observed on day 18, but T/C was 13% after 50 mg/kg and 11% after 100 mg/kg on day 22.
Potent efficacy was achieved with an intermittent dosing schedule (2 oral doses/week) at 100 or 200 mg/kg.
-
Animal Model:NOD/SCID[5]
-
Dosage:200 mg/kg/dose; 100 mg/kg/dose (survival studies)
-
Administration:gavage; daily ×5 per week
-
Result:Alone or with rapamycin decreased in vivo tumor proliferation over time compared with untreated mice.
At 200 mg/kg/dose, no difference in survival could be detected.
Survival studies at 100 mg/kg/dose were ongoing.
