IZCZ-3 (2.1 μM-15.9 μM; 24 hours) significantly inhibits SiHa, HeLa, Huh7, and A375 cancer cell proliferation (IC50s of 3.3, 2.1,4.1, and 4.2 μM, respectively). IZCZ-3 induces only weak growth inhibition in the BJ fibroblasts (IC50=15.9 μM) and mouse mesangial cells (IC50=15.6 μM), suggesting that IZCZ-3 is more effective against cancer cells than against c-MYC-independent normal cells.
IZCZ-3 (0-5 μM; 12 hours) induces an apparent accumulation of cells in the G0/G1 phase in SiHa cells in a dose-dependent manner.
Cell Proliferation Assay
Cell Line: |
SiHa, HeLa, Huh7, and A375 cancer cells (with overexpression of c-MYC protein) and in normal BJ fibroblasts and primary cultured mouse mesangial cells (with relatively low expression of c-MYC protein). |
Concentration: |
2.1 μM-15.9 μM |
Incubation Time: |
24 hours |
Result: |
IC50s of 3.3, 2.1,4.1, and 4.2 μM for SiHa, HeLa, Huh7, and A375 cancer cells; IC50s of 15.9 μM and 15.6 μM for BJ fibroblasts and mouse mesangial cells. |
Cell Cycle Analysis
Cell Line: |
SiHa cells |
Concentration: |
0, 1.25, 2.5, and 5 μM |
Incubation Time: |
12 hours |
Result: |
Induced an apparent accumulation of cells in the G0/G1 phase (increasing from 61% to 70%) in a dose-dependent manner. |
