Tegatrabetan (BC-2059、BC2059、Tegavivint) 是一种口服生物可利用的 β-连环蛋白拮抗剂。

Tegatrabetan (BC-2059, BC2059, Tegavivint) is an orally bioavailable β-catenin antagonist that disrupts the binding of β-catenin to TBL1 and promotes β-catenin degradation, attenuates nuclear and cytoplasmic levels of β-catenin; reduces transcriptional activity of TCF4 and expression of its target genes, cyclin D1, c-MYC and survivin. BC treatment dose-dependently induced apoptosis of cultured and primary AML BPCs; significantly improves the median survival of immune-depleted mice engrafted with either cultured or primary AML BPCs.Blood Cancer Phase 1 Clinical(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.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.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.(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.

Cell Proliferation Assay 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 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 Cell Line:OCI-AML3, HL-60 and MV4-11 cells Concentration:100 nM Incubation Time:24 hours Result:Treatment depleted β-Catenin expression levels.

Treatment with Tegatrabetan (10 mg/kg/day; intravenously) alone further improves the median survival to 51.5 days. Animal Model:NOD/SCID mice bearing OCI-AML3 xenografts 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.
