  摘要：

  Linear and cyclic hexapeptides composed of epsilon-(3-hydroxy-1,4-dihydro-2-methyl-4-oxo-1-pyridyl)-L,norleucine and glycine or P-alanine residue have been successfully synthesized. These hexapeptides formed 1:1 iron(III) complexes at neutral pH region. Glycine linear (8a)- and beta -alanine cyclic hexapeptide (10)-iron(III) complexes predominantly existed in Delta -configuration, while P-alanine linear hexapeptide (8b)-iron(III) complex existed in Lambda -one. The relative stability constants of 8a, 8b, and 10-iron(III) complexes were estimated to be 31.6, 33.4, and 31.7, respectively. From iron(III) removal from human transferrin, linear hexapeptides (8a,b) were found to efficiently remove iron(III) compared with desferrioxamine B. The growth-promotion activity was also discussed.
