New compounds: N1,N8-bis(2,3-dihydroxybenzoyl)spermidine and analogs as potential iron-chelating drugs

N1,N8-bis(2,3-dihydroxybenzoyl)spermidine was synthesized and evaluated as an iron-chelating drug. Homologs were prepared and evaluated together with a series of N,N'-bis(2,3-dihydroxybenzoyl)-alpha,omega-diaminoalkanes. Analogous 2-hydroxbenzoyl compounds also were synthesized and evaluated.
