Chemical Structure
Obexelimab
Synonym(s): XmAb5871
- CAS No.: 1690307-05-1
- Formula:N/A
- Molecular Weight:(147.24 kDa)
IUPAC Name: (2R,3R,4S,5R,6R)-5-hydroxy-6-(hydroxymethyl)-2-(1H-indol-1-yl)-4-(phosphonooxy)tetrahydro-2H-pyran-3-yl 3-methylbutanoate
SMILES: [Obexelimab]
Biological Activity: Obexelimab (XmAb5871) is a humanized anti-CD19 antibody. Obexelimab works by inhibiting B cell receptor (BCR) mediated calcium influx and promoting the phosphorylation of Fc γ receptor IIb (FcγRIIb), which reduces B cell activation and function, leading to B cell apoptosis. Obexelimab can be used in research for rheumatoid arthritis and systemic lupus erythematosus[1][2][3].
