新型铁螯合剂N,N'-双(2-羟基苯基)乙二胺-N,N'-二乙酸(1),双内酯2,N,N'-双(2-羟基苄基)-2-羟基丙烯-1, 3-二胺-N,N'-二乙酸(3)及其甲酯内酯4和N,N'-双(2-羟基苄基)乙二胺-N,N'-二乙酸的一系列酯(5)用超输血的铁超负荷小鼠模型制备了它们的铁螯合功效和毒性。将生物学活性与使用高输血大鼠获得的结果进行比较。酯化增强了口服铁螯合活性,但也增加了毒性。5的二异丙酯表现出最高的治疗指数。体外测量表明,在pH 7时酯水解的速率。在5 X 10(-4)M铁离子存在下,5的含量增加10(4)倍,这可能解释了酯和内酯作为前药的效用。筛选了其他十七种螯合剂,但没有腹膜内或口服活性。

Complexes of archetypal compounds 2-(2-amino-ethylamino)-benzoic acid (1) and 2-[(pyridin-2-ylmethyl)-amino]-benzoic acid (2) have been prepared with Co, Ni, and Cu. These complexes have been examined by UV-Vis and IR spectroscopy. The structure of [(Co center dot 2)Cl] has been studied by X-ray crystallography.
