The (S)-desferrithiocin (DFT) skeleton is shown to be a useful pharmacophore on which to design orally effective iron chelators. While the study clearly indicates that formal reduction of the desazadesmethyldesferrithiocin thiazoline to a thiazolidine (6), expansion of the desmethyldesferrithiocin thiazoline to a thiazine (7), or substitution of the thiazoline sulfur of desazadesmethyldesferrithiocin by an oxygen (8 and 9) lead to a substantial loss of activity, conversion of (S)-desmethyldesferrithiocin (1) to an N-methylhydroxamate (4) or to the hexacoordinate dihydroxamate ligand (5) results in active compounds. This investigation thus demonstrates which structural components of the siderophore are required for iron clearance after oral administration and suggests the use of the desferrithiocin platform as a vector for other chelators.

Les spectres RMN de 1 H a 300 MHz montrent que le coordinat existe sous forme de 3 conformeres separes tandis que le chelate ne forme exclusivement que la forme Λ-cis. Discussion

Disclosed herein are new compounds of desazadesferrothiocin polyether (DADFT-PE) analogues, as well as pharmaceutical compositions comprising them and their application as metal chelation agents for the treatment of disease. Methods of chelation of iron and other metals in a human or animal subject are also provided for the treatment of metal overload and toxicity.
A short, high-yield, flexible synthesis is described for accessing vulnibactin and related siderophores, e.g., vibriobactin analogues and homologues. The spectral properties of the synthetic vulnibactin are identical with those reported for the natural product, thus confirming the proposed structure of vulnibactin.
