2-(((2-(4-Ethylphenyl)-5-methyl-1,3-oxazol-4-yl)methyl)sulfanyl)-N-(2-phenylethyl)acetamide, Inhibitor of β-Catenin Responsive Transcription, Wnt Pathway Inhibitor VIII, C3
A cell-permeable oxazole compound that acts as a selective CRT (β-catenin responsive transcription) inhibitor (IC50 = 8.2 nM against Wnt3a-dependent SuperTopFlash STF16-luc reporter activity in HEK293 cultures) by interfering with β-cat-TCF4 interaction via direct β-catenin (β-cat) binding, while exhibiting much reduced activity against Hedgehog, Jak/Stat, or Notch signaling pathway-dependent transcription activation. Effectively inhibits cellular expression of CRT target genes, including WISP1, AXN2, and CYCD1, in a dose-dependent manner (25 to 75 µM), and selectively inhibits the proliferation of HCT116 (75 µM), HT29 (75 µM), and several primary human colon cancer cultures (6.25 to 100 µg/ml; average IC50 ~36 µg/ml) that require sustained Wnt/CRT activity for survival.

(E)-1-(2,4-dihydroxy-6-methoxyphenyl)-3-phenylprop-2-en-1-one, Wnt Pathway Inhibitor VII, Cardamonin
Cardamonin, a known 2′,4′-dihydroxy-6′-methoxychalcone, was identified as an inhibitor of melanocyte differentiation, among many other pharmacology activities. Cardamonin promoted degradation of intracellular β-catenin while suppressing melanogenesis by down-regulating the expression of MITF and tyrosinase, resulting in decreased melanin content. Furthermore, it was found that cardamonin promoted the degradation of β-catenin through a GSK-3β-independent mechanism, which suggested that Siah-dependent pathway and/or a PKCα-dependent pathway, rather than a GSK-3β-dependent pathway, may mediate intracellularb-catenin degradation by cardamonin.

1,6-Dimethylpyrimido[5,6-e][1,2,4]triazine-5,7-dione, Wnt Pathway Inhibitor X
A synthetic cell-permeable actinobacteria pyrimidotriazine-dione that selectively disrupts β-catenin-Tcf4 interaction (IC50 = 0.8 µM in cell-free binding assays) and inhibits β-catenin-regulated cellular transcription activity (IC50 = 0.3 µM in HCT116-based reporter assays). PKF118-310 is demonstrated to reverse β-catenin, but not siamois, mRNA-induced ventral body axis formation in Xenopus embryos, while direct tumor site injection (1 mg/kg/0.5 wk) in HepG2 xenograph mice is shown to increase the number of apoptotic cells and decrease the expression of β-catenin target genes (cyclin D1, c-Myc, survivin) in the tumor mass, resulting in an effective tumor growth retardation (by ~60% after a 4-wk treatment period) in vivo.

Copper, di-µ-chlorobis[1-[(1-piperidinyl-κN)methyl]-2-naphthalenolato-κO]di-(9Cl), Wnt Pathway Inhibitor XV
A cell-permeable dimeric copper complex that competitively binds β-catenin and disrupts β-catenin/Tcf4 interaction reversibly (IC50 = 5.0 µM), and acts as a Wnt signaling inhibitor. Shown to induce preferential growth arrest in β-catenin overexpressing HCT116 colon cancer and HEK293 cells (≤ 10 µM), and downregulate mRNA expressions of c-Myc and cyclin D1. Reported to inhibit PP2C and proteasomal activities at higher concentrations (~50 µM).

Description
Antigen: human β-catenin amino acids 43-62 (APSLSGKGNPEEEDVDTSQV) · Host: rabbit · Application(s): WB and IHC · β-Catenin is a multifunctional protein known to be part of the Wnt pathway, playing essential roles in development and carcinogenesis.1↗,2↗,3↗ β-Catenin can act as a regulator of the cell cycle and apoptosis in a variety of different cell systems.4↗,5↗ The entire primary amino acid sequence is identical among human, rat, and mouse, indicating critical functions of this protein6↗,7↗,8↗. Cayman Chemical’s β-catenin polyclonal antibody can be used for Western blot and immunohistochemical (formalin-fixed paraffin-embedded tissue) analysis of β-catenin on samples of human, murine, rat, porcine and bovine origin. Use of this antibody for other species and applications has not yet been tested.
