Chelating agents action on rat prostate

Design of therapeutic chelating agents.

The successful design of orally active non-toxic selective metal chelators is a much sought-after goal. In order to identify an ideal chelator for clinical use, a range of specifications must be considered, such as metal selectivity and affinity, kinetic stability of the complex, bioavailability and toxicity. In this overview the comparative properties of ligands capable of endowing complexes w...

Chelating agents in biological systems.

Chelation enables metals to be transported to or from vulnerable target sites, and to hinder or facilitate their carcinogenic potential. In the reverse sense, metals are capable of ligand scavenging via complexation or mixed complex formation--the latter being the result of interaction with binary complexes. Consequently, metal complexes can be utilized for the transport of selected organic che...

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-...
