体外研究
(In Vitro) | SC-58125 (0.001-100 μM) has a high degree of selectivity for the inducible form of COX-2 (IC50=1 μM) over the COX-1 (IC50>100 μM)[1].
SC-58125 (10 μM; 20-140 s) is time-dependent and is complete by 1 min, with a half-maximal inhibition at 20 s[1].
SC-58125 (25-100 μM; 3 d) inhibits the in vitro growth of HCA-7 and LLC cells[3].
SC-58125 (100 μM; 12 h) induces G2arrest in LLC cells[3].
SC-58125 (25-100 μM; 3 d) decreases p34cdc2levels in HCA-7 cells[3].
SC-58125 (100 μM; 24 or 72 h) does not induce apoptosis of HCA-7 and LLC cells[3].
Cell Proliferation Assay[3] | Cell Line: | HCA-7 and LLC cells | | Concentration: | 0, 25, 50, 100 μM | | Incubation Time: | 3 days | | Result: | Reduced the cell number and MTT activity in both cell lines in a dose-dependent manner. |
Cell Cycle Analysis[3] | Cell Line: | LLC cells | | Concentration: | 100 μM | | Incubation Time: | 12 hours | | Result: | Increased in the number of cells containing 4n DNA content in a dose- and time-dependent manner.
Reduced the number of mitotic figures. |
Western Blot Analysis[3] | Cell Line: | HCA-7 cells | | Concentration: | 0, 25, 50, 100 μM | | Incubation Time: | 3 days | | Result: | Resulted in a dose-dependent decrease in p34cdc2activity with strong inhibition, even at the lowest concentration. |

(In Vivo) | SC-58125 (10 mg/kg; i.p. every 48 h) inhibits the growth of established colorectal cancer xenografts in mice[3].
SC-58125 (10 mg/kg; a single i.p.) reduces tumor PGE2 levels in mice[3].
SC-58125 (10 mg/kg; a single i.p.) does not change the tumor levels of COX-1 and COX-2 protein in mice[3].
| Animal Model: | Athymic Sprague-Dawley mice are injected HCA-7 cells[3] | | Dosage: | 10 mg/kg | | Administration: | I.p. every 48 h; at the time of tumor implantation or 2 and 4 weeks later | | Result: | Decreased the tumor growth rates significantly. |
