Anzurstobart
Based on 1 Customer Validation
Anzurstobart (CC-95251; BMS-986351) is a CD47/SIRPα inhibitor with human SIRPα Kd of 0.0541 nM and human SIRPα IC50 of 100 nM. Anzurstobart binds SIRPα at a CD47-overlapping site, blocks CD47-SIRPα interactions, inhibits CD47-SIRPα axis signaling, and binds across 6 prevalent human SIRPα haplotypes. Anzurstobart binds SIRPγ and inhibits CD47-SIRPγ interactions. Anzurstobart can be used for the research of non-Hodgkin's lymphoma, colorectal cancer, squamous cell carcinoma of the head and neck, diffuse large B-cell lymphoma, and advanced solid and hematologic malignancies.

Biological Activity
Human IgG1 kappa
Human
SIRPa/CD172a
Anzurstobart (CC-95251) potently blocks CD47-SIRPα binding in a dose-dependent manner, with near-complete inhibition at 100 nM[1].
Anzurstobart (50 nM; 180 seconds) demonstrates strong binding coverage across the six most prevalent human SIRPα haplotypes[1].
Anzurstobart (20 nmol/L; 10 minutes preincubation, 3-hour coculture) alone dose-dependently increases macrophage-mediated phagocytosis of GP2d, GP5d, and SW480 colorectal cancer cells[1].
Anzurstobart (20 nmol/L; 10 minutes preincubation, 3-hour coculture) in combination with Rituximab (HY-P9913) dose-dependently enhances macrophage-mediated phagocytosis of OCI-Ly3, RIVA, Pfeiffer, and Karpas 422 DLBCL cells, while Anzurstobart alone has limited phagocytic activity[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Anzurstobart (10-100 mg/kg; i.v.) is well-tolerated in healthy cynomolgus monkeys with no hematologic depletion observed[2].
