The effect of inhibitors and intermediates of heme synthesis, inhibitor of globin synthesis, and some iron proteins on in vitro iron uptake and haemoglobin synthesis by reticulocytes of iron deficient subjects was investigated in this study. Lead, INH, ALA, mesoprophyrin, ferritin and albumin substantially increased iron uptake by iron deficient reticulocytes, while cycloheximide and glycine depressed it. The results showed that it is possible to stimulate iron uptake and Hb synthesis in iron deficiency by substances other than iron; the most effective and remarkable of them was ferritin.

A prochelator named BHAPI (N'-(1-(2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyloxy)phenyl)ethylidene)isonicotinohydrazide) based on the structure of experimental metal chelator HAPI (N'-[1-(2-hydroxyphenyl)ethyliden]isonicotinoylhydrazide) has been synthesized. The prochelator, which shows limited affinity for metal ions, is converted efficiently upon reaction with hydrogen peroxide into its chelator form, which binds di- and trivalent metal ions, including Zn(2+), Cu(2+) and Fe(3+). This work shows that the prochelator has a protective effect on cells under oxidative stress induced by either hydrogen peroxide or the cytotoxic herbicide paraquat. The effect of BHAPI and HAPI on cellular iron status was assessed by monitoring the mRNA level of the transferrin receptor. Whereas the chelator HAPI induces iron deficiency in cultured retinal pigment epithelial cells, the prochelator does not, providing evidence that the differential metal-binding capacity of these compounds observed in vitro is replicated in the cellular context.
