CBP p300 ligand 3, a specific target protein ligand of CBPD-268, modulates the function of CBP and p300. These two proteins, which possess histone acetyltransferase (HAT) activity, are crucial in the regulation of gene expression, cell proliferation, differentiation, and DNA repair by acetylating histones and other proteins. This ligand operates by binding to a particular domain within the CBP p300 proteins (the bromine domain or HAT domain), either inhibiting their enzymatic activity or altering their interactions with other proteins (transcription factors). CBP p300 ligand 3 is applicable in research on cancer, neurodegenerative diseases, and other conditions marked by abnormal CBP p300 activity.

EP300 CBP ligand 2 (compound S19) serves as a specific ligand for the bromodomain of CREB binding protein (CBP) and E1A-associated protein (EP300). It plays a critical role in PROTAC technology by acting as a target protein ligand. By linking to an E3 ubiquitin ligase ligand via the PROTAC Linker, it facilitates the synthesis of PROTAC molecules capable of targeted protein degradation. For instance, when EP300 CBP ligand 2 is connected to the conjugate (E3 ubiquitin enzyme ligand + Linker) Thalidomide-NH-C10-Boc, it results in the formation of the PROTAC molecule dCE-2.
