Certepetide
Based on 1 Customer Validation
Certepetide (CEND-1) is a bifunctional cyclic peptide (a.k.a. iRGD). Certepetide is a tumor-penetrating enhancer via RGD motif interaction with alphav-integrins and via activating NRP-1, and transforms the solid tumor microenvironment into a temporary agent conduit. Certepetide accumulates in tumors, and is used in the research of pancreatic cancer and other solid tumors.

Activité biologique
Alphav-integrins, NRP-1[3].
CEND-1 enhances the penetration of anticancer therapeutics specifically into tumours, but not into normal tissues, it also holds the potential for dose reductions, which can attenuate side effects[4].
CEND-1 (intravenously injected) increases the levels of co-administered Evans blue approximately threefold[5].
