Abstract Several derivatives of the coprogen and ferrichrysin classes of siderophores were synthesized as potential affinity labels of the iron uptake system inNeurospora crassa. While only one of these compounds has proved useful as an affinity label, all were recognized and transported byNeurospora crassa. One derivative, chloroacetyl-ferrichrysin, proved to be an unexpectedly potent reversible inhibitor (K 1=0.4 μM) of both ferrichrysin and coprogen uptake, similar to the natural siderophore, ferrirubin. The reported results provide further understanding of the steric and electronic requirements of siderophores for the iron uptake system inNeurospora crassa.
