CBP Tag Inhibitors

CBP Tag Inhibitors comprise a range of compounds that indirectly inhibit the functional dynamics of CBP, a transcriptional coactivator involved in gene expression regulation and chromatin remodeling. These inhibitors operate through diverse mechanisms, influencing pathways and processes crucial for CBP's activation and function. They do not directly target the CBP Tag but affect the cellular environment or signaling cascades that indirectly modulate CBP's role in transcriptional coactivation. Chemicals such as Indirubin-3'-monoxime, Kenpaullone, and K-252a target kinases like CDKs and GSK-3, which are integral to various signaling pathways that ultimately influence transcription regulation, potentially impacting CBP's activity. Compounds like C646, Garcinol, and Anacardic Acid specifically inhibit CBP/p300 histone acetyltransferase (HAT) activity. This inhibition leads to reduced histone acetylation, a key process in chromatin remodeling that facilitates transcriptional activation. By inhibiting HAT activity, these compounds can decrease the transcriptional coactivation capability of CBP.
