Zinc protoporphyrin IX (Synonyms: ZnPPIX) |
Catalog No.GC11208 |
Le zinc protoporphyrine IX (ZnPP) est un membre des métalloporphyrines dans lequel le fer de l'hème est remplacé par du zinc, devenant ainsi un inhibiteur compétitif de l'hème oxygénase 1 (HO-1).

Zinc protoporphyrin IX (ZnPP) is a member of metalloporphyrins in which the heme iron is replaced by zinc, which becomes a competitive inhibitor of heme oxygenase 1 (HO-1) [1].
Zinc protoporphyrin IX tested presented anti-vesicular stomatitis virus (VSV) activity without photoactivation, with the reduction in viral titer being about 10-fold for 1 µM Zinc protoporphyrin. At 5 µM, Zinc protoporphyrin IX tested were able to completely abolish VSV infectivity. Photoactivation of the porphyrins significantly enhanced their antiviral activities, with 0.1 µM ZnPPIX completely abolishing VSV infectivity [2]. Zinc protoporphyrin IX (ZnPP) (5 µM; 72 hours) causes the fraction of late apoptotic and necrotic cells increasing from 10.9% in controls to 30.4% after 72 h in C-26 cells[3]. Zinc protoporphyrin IX (1.25-40 µM; 48 or 72 hours) exerts cystostatic/cytotoxic effects against human ovarian carcinoma (MDAH2774), human pancreatic adenocarcinoma (Mia PaCa2), human breast carcinoma (MDA-MB231), murine breast carcinoma (EMT6) cell lines [3].
Zinc Protoporphyrin IX (12.5, 25, 50 mg/kg for i.p.; 12.5, 50 mg/kg for p.o. for 7days) exerts dose-dependent antitumor effects manifested by the retardation of tumor growth in BALB/c mice inoculated with C-26 cells [3]. Zinc Protoporphyrin IX (5 and 20 µg/mouse) dose-dependently inhibited tumor growth in LL/2-tumor model mice. Vascular endothealial growth factor concentration in tumors was reduced by Zinc Protoporphyrin IX [4].
