CM112 is a selective degrader of protein arginine methyltransferase 1 (PRMT1), which connects a hydrophobic adamantane tag to MS023 via a 5-PEG linker. It induces the degradation of PRMT1 in various solid tumor cell lines. CM112 also targets the non-enzymatic functions of PRMT1 by reducing the stability of the orphan receptor TR3. This compound shows potential for cancer research.
