Cell Viability Assay
Cell Line: |
A549, H1299, H226 and HUVEC cells |
Concentration: |
0, 0.025, 0.05, 0.075 and 1 μM |
Incubation Time: |
48 h |
Result: |
Inhibited cell viability with IC50s of 0.109±0.01, 0.055±0.004, 0.077±0.005 and 0.536±0.166 μM against A549, H1299, H226 and HUVEC cells, respectively. |
Cell Cycle Analysis
Cell Line: |
A549, H1299 and H226 |
Concentration: |
0.05, 0.1 and 0.3 μM |
Incubation Time: |
24 and 48 h |
Result: |
Treatment for 24 h led to notable accumulation of cells in the G2/M phase. At 48 h, sub-G1 apoptotic cell populations were increased in a concentration-dependent manner. Cells in the G2/M phase began to rise at 12 h post-treatment and peaked at 24 h. Following this, there was an emergence of cells in the sub-G1 population phase until 48 h. |
Western Blot Analysis
Cell Line: |
A549, H1299 and H226 |
Concentration: |
0.05, 0.1 and 0.3 μM |
Incubation Time: |
24 h |
Result: |
Resulted in a marked increase in expression of the mitosis marker MPM2 and the proteins cyclin B1, Cdc2, Thr161, Aurora A and Aurora B in a concentration-dependent manner. Decreased the expression of Cdc (Tyr15) and Cdc25C, whereas total protein levels of Cdc2 did not change. |
Apoptosis Analysis
Cell Line: |
A549 |
Concentration: |
0.05, 0.075, 0.1 and 0.3 μM |
Incubation Time: |
48 h |
Result: |
Induced apoptosis in a concentration-dependent manner. |
Western Blot Analysis
Cell Line: |
A549 |
Concentration: |
0.05, 0.1 and 0.3 μM |
Incubation Time: |
24, 36 and 48 h |
Result: |
Induced activation of caspases-3, -7, -8 and -9, and cleavage of PARP in a time- and concentration-dependent manner. Significantly induced Bcl-2 phosphorylation. Down-regulated Mcl-1 expression in a concentration-dependent manner.

体内研究 (In Vivo) |
MPT0B014 (100 mg/kg; i.v./i.p.; daily for 25 days) 和 25 mg/kg Erlotinib (HY-50896) 联用显著改善小鼠 A549 肿瘤抑制。
西域 has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Model: |
Nude athymic mice, A549 xenografts |
Dosage: |
100 mg/kg alone or in combination with 25 mg/kg Erlotinib (HY-50896) |
Administration: |
i.v./i.p., daily for 25 days |
Result: |
The combined treatment resulted in more significant tumor growth delay (28%) compared with treatment alone (7%). The combination produced significantly higher anti-tumor activity. The growth of A549 cancer cell xenografts was suppressed by 11, 21 and 49% (tumor growth inhibition) after treatment with MPT0B014, Erlotinib and MPT0B014 plus Erlotinib, respectively.
