Deferoxamine, deferiprone, and deferasirox are used for the treatment of systemic iron overload, although they possess limitations due to lack of oral activity, lower efficacy, and side effects. These limitations led to a search for an orally active iron chelator with an improved therapeutic index. The lower efficacy of deferiprone is due to rapid glucuronidation, leading to the formation of a nonchelating
去铁胺,去铁酮和地拉罗司用于治疗全身性铁超负荷,尽管由于缺乏口服活性,疗效较低和副作用而存在局限性。这些限制导致寻找具有改善的治疗指数的口服活性铁螯合剂。去铁酮的功效较低是由于快速的葡萄糖醛酸化作用,导致形成非螯合的代谢产物。在这里,我们证明可以通过引入牺牲部位进行葡萄糖醛酸化来减少新陈代谢的影响。在对数P指导下对20个羟基吡啶并酮的研究导致CN128的鉴定。CN128的Fe(III)亲和力和金属选择性与去铁酮相似,log P值更具亲脂性,并且其铁清除能力优越。总体,
