| Description | |

| Overview | The racemic mixture of a cell-permeable (4-methoxyphenyl)chloroacrylaldehyde compound whose (Z)-isomer (isomer content 12-15%) acts as a p300-selective histone acetytransferase (HAT) inhibitor (IC50 = 4.2 µM using racemic mixture with 13% Z-isomer) and selectively disrupts β-catenin association with p300, but not CBP or LEF1/TCF4, exhibiting much reduced potency against KAT5, CBP, MYST4, MYST2 (IC50 ≥38 µM) and little or no inhibitory efficacy toward GCN5 and PCAF HAT activity (IC50 >100 µM). Shown to selectively prevents human & mouse β-catenin-, zebrafish β-catenin-1-, but not zebrafish β-catenin-2-, mediated transcription activity without affecting β-catenin activation or nuclear translocation. Induces apoptosis in Wnt signaling-dependent cancer cultures (IC50 15 to 22 µM; 72 h) in vitro without affecting the viability of Wnt-independent H460 (up to 200 µM & 72 h) and selectively abrogates Wnt signaling in ventral & lateral regions, but not within dorsal organizer, in 5.3 hpf epiboly stage zebrafish embryos in vivo. A great complement to the selective β-catenin-CBP interaction blocker ICG-001 (Cat. no. 504712). (E)-isomer is available separately (Cat. no. 509166) as negative control. |
