Zinc Protoporphyrin (Zn(II)-protoporphyrin IX) is an orally active and competitive heme oxygenase-1 (HO-1) inhibitor and markedly attenuates the protective effects of Phloroglucinol (PG) against H2O2. Zinc Protoporphyrin is used as a screening marker of iron deficiency in individual pregnant women and children, but also to assess population iron status in combination with haemoglobin concentration. Zinc Protoporphyrin has anti-cancer activity.

72 hours) causes the fraction of late apoptotic and necrotic cells increasing from 10.9% in controls to 30.4% after 72 h[3]. Zinc Protoporphyrin (1.25-40 μM
48 or 72 hours) exerts cytostatic/cytotoxic effects against tumor cells[3]. Zinc Protoporphyrin (2.5, 5 μM
48 or 72 hours) results in dose- and time-dependent reduction of cells in the G1 phase of the cell cycle[3]. Zinc Protoporphyrin (1.25-40 μM
48 hours) leads to the accumulation of cleaved (active) caspase-3[3].
Zinc Protoporphyrin (12.5, 25, 50 mg/kg for i.p.
12.5, 50 mg/kg for p.o.
from day 7 to 19) exerts dose-dependent antitumor effects manifested by the retardation of tumor growth[3].
