MS182 (compound 11), an acetylation targeting chimera (AceTAC), incorporates p53 Y220C stabilizers with p300/CBP binders, connected via a linker. This design enables MS182 to selectively form a ternary complex with p300/CBP acetyltransferase and the mutant p53 Y220C, subsequently catalyzing specific acetylation of lysine at position 382 in a time- and concentration-dependent manner, achieving an ACE 50 of 1.52 µM. Additionally, MS182 demonstrated significant bioavailability in mice, with GI 50 values recorded at 2.16 µM for BxPC3 (p53 Y220C/-) and 1.83 µM for NUGC (p53 Y220C/+).
