体外研究
(In Vitro) | Tegatrabetan (BC2059; 20-100 nM; 48 hours) inhibits cell proliferation in suspension culture over 120 hours and induces apoptosis of cultured human acute myeloid leukemia (AML) HL-60, OCI-AML3 and MV4-11 cells dose-dependently[1].
Tegatrabetan (20 and 50 nM; 24 hours) induces a modest but significant accumulation of cells in the G0/G1 phase, with a concomitant decline in the G2/M phase of the cell cycle[1].
Tegatrabetan (100 nM, 24 hours) depletes the levels of β-catenin and its target genes, including c-MYC and survivin without affecting the levels of the TBL1 in OCI-AML3, HL-60 and MV4-11 cells[1].
Cell Proliferation Assay[1] | Cell Line: | HL-60, OCI-AML3 and MV4-11 cells | | Concentration: | 20, 50, and 100 nM | | Incubation Time: | 48 hours | | Result: | Dose-dependently inhibited cell proliferation. |
Cell Cycle Analysis[1] | Cell Line: | OCI-AML3 cells | | Concentration: | 20 and 50 nM | | Incubation Time: | 24 hours | | Result: | Dose-dependently induced cell cycle growth arrest. |
Western Blot Analysis[1] | Cell Line: | OCI-AML3, HL-60 and MV4-11 cells | | Concentration: | 100 nM | | Incubation Time: | 24 hours | | Result: | Treatment depleted β-Catenin expression levels. |

体内研究
(In Vivo) | Tegatrabetan (BC2059; 1.0 or 5.0 mg/kg/day; intravenously) significantly improves the median survival of the mice from approximately 17.5 to 39 days. Treatment with Tegatrabetan (10 mg/kg/day; intravenously) alone further improves the median survival to 51.5 days[1].
| Animal Model: | NOD/SCID mice bearing OCI-AML3 xenografts[1] | | Dosage: | 1 mg/kg; 5 mg/kg; 10 mg/kg | | Administration: | Intravenously; 1 mg/kg daily 4 days per week or 5 mg/kg or 10 mg/kg of BC2059 twice per week (Tuesday and Thursday) for 3 weeks. | | Result: | Treatment significantly improved survival of NOD/SCID mice bearing OCI-AML3 xenografts. |
