β-catenin/p300

ICG001 is a β-catenin TCF-mediated transcription inhibitor that selectively blocks β-catenin CBP interaction without interfering with β-catenin p300 interaction. It specifically binds to CREB protein with an IC50 of 3 μM.

Bisdemethoxycurcumin (Curcumin III) is a natural demethoxy derivative of curcumin. It is a potent activator of macrophage phagocytosis, interacting with 1α, 25-dihydroxy vitamin D3 to stimulate amyloid-β clearance by macrophages (optimal stimulation at 100 nM BDMC) [1]. More stable than curcumin in physiological media, BDMC suppresses proliferation of cancer cells [2]. It down-regulates the transcriptional coactivator p300, suppressing the Wnt β-catenin pathway, and inhibits LPS induction of iNOS expression [3].

ICG001 antagonizes Wnt β-catenin TCF-mediated transcription and specifically binds to element-binding protein (CREB)-binding protein (CBP) with IC50 of 3 μM, but is not the related transcriptional coactivator p300.

IQ 1 has multiple roles, such as maintaining the multifunctionality of mouse ESCs, decreasing Wnt-stimulated phosphorylation, blocking PP2A Nkd interactions, and so on.

C-82 is a specific CBP β-catenin antagonist. It inhibits the binding between β-catenin and CBP and increases the binding between β-catenin and p300.

YH249 is the first highly specific direct antagonist of p300 β-catenin.
