A member of the class of thiazolidines that is (4R)-3-methyl-1,3-thiazolidine-4-carboxylic acid which is substituted at position 2 by a (4R)-2-(2-hydroxyphenyl)-4,5-dihydro-1,3-thiazol-4-yl group. A siderophore that is produced by Pseudomonas aeruginosa (via condensation of salicylic acid and two molecules of cysteine) as a mixture of two easily interconvertible diastereoisomers, pyochelin I (major) and pyochelin II (minor). The enantiomeric compounds, enant-pyochelin, are produced by Pseudomonas fluorescens.

| pyochelin-II | A pyochelin that has S-stereochemistry at the thioaminal centre; the diastereoisomer with R-stereochemistry at this centre is pyochelin I. Pseudomonas aeruginosa produces a mixture of pyochelin I (major) and pyochelin I (minor) via condensation of salicylic acid and two molecules of cysteine. The enantiomeric compounds, enant-pyochelin I and II, are produced by Pseudomonas fluorescens. | |

Synthesis and biological properties of thiazole-analogues of pyochelin, a siderophore of Pseudomonas aeruginosa.
Pyochelin is a siderophore common to all strains of Pseudomonas aeruginosa utilized by this Gram-negative bacterium to acquire iron(III). FptA is the outer membrane transporter responsible of ferric-pyochelin uptake in P. aeruginosa. We describe in this Letter the synthesis and the biological properties ((55)Fe uptake, binding to FptA) of several thiazole analogues of pyochelin. Among them we report in this Letter the two first pyochelin analogues able to bind FptA without promoting any iron uptake in P. aeruginosa. |
