MY-1B
- CAS No.: 2929308-79-0
- Formula:C22H18BrN3O2
- Molecular Weight:436.30
InChIKey: DXMLBCROCLGUDK-DYESRHJHSA-N
SMILES: O=C([C@H]1[C@@H](C2=CC=C(C=C2)Br)CN1C(C=C)=O)NC3=CC=CC4=C3N=CC=C4
Biological Activity: MY-1B is a covalent inhibitor of the RNA Methyltransferase NSUN2 (IC50: 1.3 μM). MY-1B stereoselectively ligands active-site cysteine residues (C271) of NSUN2. MY-1B can stereoselectively and covalently bind to PSME1, disrupting the proteasome regulatory complex and downregulating the presentation of specific MHC-I subtypes[1][2][3].
