CL121
CL121 is a Glutaminyl Cyclase inhibitor with an IC50 of 0.07 μM against human sQC and an IC50 of 0.54 μM against human gQC. CL121 reduces the level of pyroglutamate (pE)-modified CD47 on the surface of cancer cells. CL121 exhibits anti-tumor activity against triple-negative breast cancer.

Biological Activity
CL121 potently inhibits purified human sQC with an IC50 of 0.07 μM and human gQC with an IC50 of 0.54 μM[1].
CL121 (10-40 μM; 72 h) reduces surface pE-CD47 modification in a dose-dependent manner on MDA-MB-231 cells without affecting total CD47 expression[1].
CL121 (10-40 μM) enhances macrophage-mediated phagocytosis of KYSE30 cells, with the most potent effect at 20 μM, while higher concentrations (40 μM) show reduced activity[1].

Result:Reduced average tumor volume to 154 mm3 (from 227 mm3 in controls) and average tumor weight to 129.05 mg (from 191.49 mg in controls) at 10 mg/kg, with statistically significant tumor weight reduction (P < 0.01).
Reduced average tumor volume to 195 mm3 and average tumor weight to 173.69 mg at 20 mg/kg, with no statistically significant difference compared to controls.
Significantly reduced intratumoral pE-CD47 expression relative to controls at both doses, with 10 mg/kg showing statistically significant reduction (P < 0.05) and 20 mg/kg showing stronger statistically significant reduction (P < 0.01).
Showed no significant differences in body weight between treatment groups and controls, indicating low systemic toxicity.
