Chemical Structure
Cinrebafusp alfa
Synonym(s): PRS 343
- CAS No.: 2218515-90-1
- Formula:N/A
- Molecular Weight:(187.87 kDa)
IUPAC Name: (S)-8-hydroxy-7-methoxy-2-(4-methoxyphenyl)-10-((2-(trimethylsilyl)ethoxy)methyl)-1,11a-dihydro-5H-benzo[e]pyrrolo[1,2-a][1,4]diazepine-5,11(10H)-dione
SMILES: [Cinrebafusp alfa]
Biological Activity: Cinrebafusp alfa (PRS 343) is a high affinity CD137/HER2 bispecfic anticalin-based drug. Cinrebafusp alfa binds to recombinant human HER2 (Kd=0.3 nM) and human monomeric CD137 (4-1BB; Kd=5 nM). Cinrebafusp alfa facilitates T-cell costimulation by tumor-localized, HER2-dependent 4-1BB clustering and activation, further enhancing T-cell receptor-mediated activity and leading to tumor destruction. Cinrebafusp alfa has the potential for HER2+ solid tumors research[1][2].
