[Study on the structure activity relationship of a phytosiderophore, mugineic acid].
To study the structure-activity relationship of mugineic acid (MA), a phytosiderophore isolated from Hordeum velugare L. var. Minorimugi, several 2-deoxymugineic acid (DMA) analogues were synthesized. 1H-NMR spectra of DMA analogues and their Co(III) complexes were first measured and analyzed to elucidate the structures of metal complexes. CD spectra of the Co(III) and Fe(III) complexes of DMA analogues were then measured and compared with those of MA. Furthermore, the interaction between the Fe(III) complexes of DMA analogues and the phytosiderophore-Fe(III) complex transporter found in maize was examined.
