摘要

The siderophore myxochelin A is a potent inhibitor of human 5-lipoxygenase (5-LO). To clarify whether the iron-chelating properties of myxochelin A are responsible for this activity, several analogues of this compound were generated in the native producer Pyxidicoccus fallax by precursor-directed biosynthesis. Testing in a cell-free assay unveiled three derivatives with bioactivity comparable with that of myxochelin A. Furthermore, it became evident that inhibition of 5-LO by myxochelins does not correlate with their iron affinities. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
