IUPAC Name: 3-((4-(1-((1-(6-(((S)-2,6-dioxopiperidin-3-yl)carbamoyl)pyridin-3-yl)piperidin-4-yl)methyl)piperidin-4-yl)phenyl)amino)-5-((R)-3-(3-methyl-2-oxoimidazolidin-1-yl)piperidin-1-yl)pyrazine-2-carboxamide
InChIKey: HPTPDBYCFHFWJG-CWTKIQHKSA-N
SMILES: NC(C1=C(N=C(N2C[C@H](N3C(N(CC3)C)=O)CCC2)C=N1)NC4=CC=C(C5CCN(CC5)CC6CCN(C7=CN=C(C(N[C@@H]8C(NC(CC8)=O)=O)=O)C=C7)CC6)C=C4)=O
Biological Activity: Bexobrutideg (NX-5948) is an orally active chimeric targeting molecule (CTM) that induces specific BTK protein degradation by the cereblon E3 ligase (CRBN) complex without degradation of other cereblon neo-substrates. Bexobrutideg mediates potent anti-inflammatory activity via BTK degradation with resultant inhibition of B cell activation. Bexobrutideg exhibits potent tumor growth inhibition in TMD8 xenograft models that contain either wild-type BTK or BTKi-resistant mutations. Bexobrutideg is efficacious in a mouse collageninduced arthritis (CIA) model. Bexobrutideg can cross the blood brain barrier (BBB). Bexobrutideg is a PROTAC composed of the ligand for target protein, a linker, and a cereblon E3 ligase (CRBN) complex (Red: BTK ligand (HY-170324); Blue: CRBN ligand (HY-171893); Black: linker)[1][2][3].
