A series of 3-hydroxypyridin-4-one derivatives (HPOs) were synthesized and their partition coefficient values (K(part)) were determined. The cytotoxic effects of these iron chelators against Hela cancer cells were also evaluated. The IC(50) of HPOs was determined using MTT assay. Among these ligands, compound 4e (K(part)=5.02) with an IC(50) of 30 μM and 4f (K(part)=0.1) with an IC(50) of 700 μ...

A simple and rapid method with low radiation exposure risk was developed for the determination of neodymium in spent nuclear fuel by capillary electrophoresis with laser-induced fluorescence detection using a fluorescent probe having a macrocyclic hexadentate polyaminocarboxylate structure. The concentration of Nd(III) in a spent nuclear fuel sample was determined with no interference from vari...

The antimalaria effect of iron chelators is attributed to their interaction with a labile iron pool within parasitised erythrocytes, and it was postulated that increased affinity to iron as well as increased lipophilicity may improve antimalarial activity. In the present study we have examined the antimalarial effect of 3-hydroxypyridin-4-ones, a family of bidentate orally effective iron chelat...
