Studies on Inhibition of Iron Corrosion by Chelating Agents

Inhibition of Naegleria fowleri by microbial iron-chelating agents: ecological implications.

Deferrioxamine B and rhodotorulic acid, iron-chelating agents of microbial origin, exerted a pronounced inhibitory effect on pathogenic Naegleria fowleri at microgram levels. This inhibition was diminished by adding iron to the chelators before incubation with Naegleria isolates. These and related microbial iron chelators occur naturally in the environment. This could be of considerable ecologi...

The Transfer of Iron to Reticulocytes by Synthetic Chelating Agents.

The effect of chelating agents on cellular iron metabolism.

1. The effect of iron chelators on iron uptake, ferritin and total protein synthesis was studied in cultured Chang cells. Desferrioxamine depressed ferritin synthesis and completely inhibited iron uptake by ferritin protein. Rhodotorulic acid reduced iron uptake by the cells but had little effect on ferritin synthesis. Diethylenetriamine pentaacetic acid produced complete inhibition of iron upt...

Iron chelating agents for treating malaria.

BACKGROUND Researchers are exploring the effects of adding treatments to the main antimalarial regimens in an attempt to reduce mortality from Plasmodium falciparum. Iron chelation is one potential chemotherapeutic adjuvant treatment. Before advocating adjunctive therapy, the effects of iron chelators in improving patient outcomes need to be examined. OBJECTIVES To assess the effects of iron-...

Synthetic chelating agents in iron metabolism.

Iron in man is held within the cells incorporated in organic complex molecules, either as functional iron, i.e., hemoglobin and tissue enzymes, or as storage iron, i.e., ferritin and hemosiderin. Owing to the requirements of the erythroid marrow in particular, large amounts of iron must constantly pass from one cell to another through the plasma. This plasma transport is brought about by a #3gl...
