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.

C82 acts as an inhibitor of Mycobacterium tuberculosis (Mtb) cyclic dinucleotide phosphodiesterase (CdnP), with an IC50 value of 17.5 µM. This particular enzyme is responsible for breaking down cyclic di-AMP (c-di-AMP) into adenosine 5'-monophosphate (AMP). Notably, C82 demonstrates selectivity for Mtb CdnP over other bacterial cyclic dinucleotide phosphodiesterases (CDN PDEs) such as Yybt, RocR, and Group B Streptococcus (GBS) CdnP, as well as the mammalian CDN PDE ENPP1, and the viral CDN PDE poxin, showing effectiveness at a concentration of 200 µM.
