Safety and pharmacokinetics of the oral iron chelator SP-420 in β-thalassemia.
Our phase I, open-label, multi-center, dose-escalation study evaluated the pharmacokinetics (PK) of SP-420, a tridentate oral iron chelating agent of the desferrithiocin class, in patients with transfusion dependent β-thalassemia. SP-420 was administered as a single dose of 1.5 (n = 3), 3 (n = 3), 6 (n = 3), 12 (n = 3), and 24 (n = 6) mg/kg or as a twice-daily dose of 9 mg/kg (n = 6) over 14-28 days. There was a near dose-linear increase in the mean plasma SP-420 concentrations and in the mean values for C Topics: Adolescent; Adult; beta-Thalassemia; Blood Transfusion; Cyclohexanones; Dihydropyridines; Dose-Response Relationship, Drug; Humans; Iron Chelating Agents; Kidney Diseases; Middle Aged; Siderophores; Thiazoles; Young Adult | 2017 |

Desferrithiocin analogues and nephrotoxicity.
The syntheses of a series of 4'-O-alkylated ( S)-4,5-dihydro-2-(2,4-dihydroxyphenyl)-4-methyl-4-thiazole-carboxylic acid and 5'-O-alkylated ( S)-4,5-dihydro-2-(2,5-dihydroxyphenyl)-4-methyl-4-thiazolecarboxylic acid ligands are described. Their partition between octanol and water, log P(app), is determined, along with their iron-clearing efficiency (ICE) in both non-iron-overloaded, bile duct-cannulated rodents and in iron-overloaded primates. The ligand-promoted biliary ferrokinetics in rats are described for each of the chelators. Plots of log P(app) versus ICE in a rodent model for both the 4'-O-alkylated 2,4-dihydroxy and 5'-O-alkylated 2,5-dihydroxy series produced an inverse parabola plot with r(2) values of 0.97 and 0.81, respectively. The plots indicate an optimum log P(app)/ICE relationship. Because of the nature of the data spread in the 4'-O-alkylated 2,4-dihydroxy series, it will be used to help assess the origin of nephrotoxicity in desferrithiocin analogues: is toxicity simply related to lipophilicity, ICE, or a combination of these properties?

A comparative study of the iron-clearing properties of desferrithiocin analogues with desferrioxamine B in a Cebus monkey model.
A comparative study of the iron-clearing properties of subcutaneously administered desferrioxamine B (DFO) with those of orally administered desferrithiocin sodium salt (1), desmethyl desferrithiocin (2), desazadesmethyl desferrithiocin sodium salt (3), desazadesmethyl desferrithiocin pivaloyloxymethyl ester (4), and desazadesmethyl-5,5-dimethyl desferrithiocin (5) in an iron-loaded Cebus monkey model and a non-iron overloaded bile duct-cannulated rat model is presented. All six drugs, which performed well in rodent studies, demonstrated increased efficiency in the Cebus monkey model. When administered to rodents at a daily dosage of 384 mumol/kg over a period of 10 days, drug 1 demonstrated severe renal toxicity. whereas drugs 3, 4, and 5 exhibited severe gastrointestinal (GI) toxicity. Under the same experimental protocol, drug 2 did not show significant toxic side effects. In addition, to further evaluate the iron-clearing properties of analogue 2, a dose-response study was performed in the primates that showed that iron excretion increased in a dose-dependent fashion.
