OBJECTIVE To evaluate the iron-chelating properties and free-radical scavenging activities of 1-(N-acetyl-6-aminohexyl)-3-hydroxy-2-methylpyridin-4-one (CM1) treatment in chronic iron-loaded β-thalassemic (BKO) mice. METHODS The BKO mice were fed with a ferrocene-rich diet and were orally administered with CM1 [50 mg/(kg.day)] for 6 months. Blood levels of non-transferrin bound iron, labile p...
In our report entitled “Treatment of Cooley’s Anemia” (Blood 76:435, 1990), we described a deferoxamine provocation test in which we measure serum iron and iron-binding capacity following an infusion of the chelator. In the report, we failed to state clearly that we do not use standard colorimetric tests to make these measurements. The mild reducing agents used in most colorimetric assays do no...
OBJECTIVES Increased bone marrow iron levels in patients with haematological malignancies is an independent risk factor for developing invasive pulmonary aspergillosis (IPA), suggesting an important role for iron uptake in the pathogenesis of IPA. We sought to determine the potential for combination therapy with the iron chelator deferasirox + liposomal amphotericin B (LAmB) to improve the outc...
To determine if the elevated transferrin saturations found in some patients with severe malaria are associated with an adverse outcome in cerebral malaria, we retrospectively measured baseline saturations in stored serum samples from 81 Zambian children with strictly defined cerebral malaria. The children had been treated with quinine, sulfadox-ine-pyrimethamine, and intravenous infusions of ei...
Strains of Pseudomonas putida, Pseudomonas sp., and Pseudomonas aeruginosa were examined for their ability to grow in the presence of the iron chelator, ethylenediamine-di-(o-hydroxyphenylacetic acid). In vitro fungal inhibition assays showed that the isolates varied in their ability to inhibit the growth of representative fungal plant pathogens. Fungal inhibition in vitro was superior to that ...
Phenanthroline, a strong iron chelator, prevents both the formation of DNA single-strand breaks and the killing of mouse cells produced by H2O2. These results, taken together with our previous findings, indicate that the DNA damage is produced by hydroxyl radicals formed when H2O2 reacts with chromatin-bound Fe2+ and that this damage is responsible for the killing effect.
All patients were treated topically with vitamin K to improve the resolution of laser-induced purpura. In the case of longlasting hyperpigmentation (more than six weeks), the patients were treated with hydroquinone (bleaching cream) and an iron chelator. Complete sun avoidance was recommended for six weeks. Posttreatment compression was unnecessary. Vbeam Pulsed Dye Laser Treatment of Leg Telan...

This study compares the biliary and urinary metabolic profiles of 1,2-diethyl-3-hydroxypyridin-4-one (CP94), an orally active iron chelator, in the normal rat. Surprisingly, CP94 was found to form two phase II metabolites, the 3-O- and 4-O-glucuronides. These glucuronides accounted for 38 and 28% of the administered CP94 dose, in bile and urine, respectively. Unchanged CP94 accounted for 5% of ...
