生物活性

β-catenin-IN-3 (Compound C2) is a selective β-catenin inhibitor. β-catenin-IN-3 binds to allosteric site on the surface of β-catenin with K D calculated at 54.96 nM. β-catenin-IN-3 selectively inhibits β-catenin via targeting a cryptic allosteric modulation site, lowers its cellular load. β-catenin-IN-3 significantly reduces viability of β-catenin driven cancer cells, and triggers β-catenin degradation via proteasome system in β-catenin-overexpressing cancer cells[1].

(In Vitro)

β-catenin-IN-3 (24 h)以剂量依赖性方式降低 DLD1,SW480,HCT116,SW48,MCF10A 和 H460 细胞的活力,IC50s为 0.85 μM、1.35 μM、5.35 μM、3.45 μM 和 20 μM 以上。[1]
β-catenin-IN-3 (1 μM,3 μM,7 天) 抑制 DLD1 和 SW48 细胞的集落形成能力。[1]
β-catenin-IN-3 (0,1,5 μM,24 h) 以剂量依赖的方式选择性抑制 DLD1 和 SW480 细胞中 β-catenin、 Axin1、 CyclinD1 和 TCF4 的水平[1]
β-catenin-IN-3 (1 μM,3 h) 在 DLD1 细胞中通过泛素-蛋白酶体机制触发 β-catenin 的降解,可能是通过募集 APC 介导的破坏复合物[1]
β-catenin-IN-3 (1 μM,1-24 h) 增加 DLD1 细胞中 β-catenin 的磷酸化[1]
β-catenin-IN-3 (1,5 μM,24 h) 分别降低了细胞核和细胞质中的
β-catenin 45%,40%,85% 和 55%[1]
β-catenin-IN-3 (3,5 μM, 4 天) 抑制 APC 缺陷类器官克隆形成能力约 70% 和 55%,相反,野生型类器官的存活率为90%[1]

Cell Viability Assay[1]

Cell Line: DLD1,SW4808, HCT116, SW48, MCF10A, H460 cells
Concentration: 10 nM-100 μM
Incubation Time: 24 h
Result: Reduced viability of DLD1 and SW480 cells in dose-dependent manner with IC50s of 0.85 μM and 1.35 μM.
Reduced viability of HCT116 and SW48 cells in dose-dependent manner with IC50s of 5.35 μM and 3.45 μM.
Impacted two WNT-independent cell lines, MCF10A and H460, with IC50 above 20μM.

Western Blot Analysis[1]

Cell Line: DLD1 cells
Concentration: 1μM
Incubation Time: 1,3,6,12,24 h
Result: Phosphorylated β-catenin starting at 1 hour point, which was further amplified to 2-2.5-fold at 12 and 24 hour points, and can be blocked by CHIR99021 (HY-10182).
Levels of active β-catenin markedly reduced at these time points, and can be arrested by MG132 (HY-13259).

Immunofluorescence[1]

Cell Line: DLD1 cells
Concentration: 1 μM
Incubation Time: 24 h
Result: Reduced β-catenin that co-localized with nucleic acids inside the nucleus by 55-60% (co-localization dropped from 0.62 to 0.25).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
