  Polyaminoquinoline Iron Chelators for Vectorization of Antiproliferative Agents: Design, Synthesis, and Validation

  摘要：

  Iron chelation in tumoral cells has been reported as potentially useful during antitumoral treatment. Our aim was to develop new polyaminoquinoline iron chelators targeting tumoral cells. For this purpose, we designed, synthesized, and evaluated the biological activity of a new generation of iron chelators, which we named Quilamines, based on an 8-hydroxyquinoline (8-HQ) scaffold linked to linear polyamine vectors. These were designed to target tumor cells expressing an overactive polyamine transport system (PTS). A set of Quilamines bearing variable polyamine chains was designed and assessed for their ability to interact with iron. Quilamines were also screened for their cytostatic/cytotoxic effects and their selective uptake by the PTS in the CHO cell line. Our results show that both the 8-HQ moiety and the polyamine part participate in the iron coordination. HQ1-44, the most promising Quilamine identified, presents a homospermidine moiety and was shown to be highly taken up by the PTS and to display an efficient antiproliferative activity that occurred in the micromolar range. In addition, cytotoxicity was only observed at concentrations higher than 100 mu M. We also demonstrated the high complexation capacity of HQ1-44 with iron while much weaker complexes were formed with other cations, indicative of a high selectivity. We applied the density functional theory to study the binding energy and the electronic structure of prototypical iron(III)-Quilamine complexes. On the basis of these calculations, Quilamine HQ1-44 is a strong tridentate ligand for iron(III) especially in the form of a 1:2 complex.

  persistent cleavage complexes, and induction of a unique pattern of DNA cleavage sites. Molecular modeling has suggested that substituents on the indenoisoquinoline lactam nitrogen would protrude out of the DNA duplex in the ternary cleavage complex through the major groove. This indicates that relatively large substituents in that location would be tolerated without compromising biological activity. As a

  茚并异喹啉类是一类非喜树碱拓扑异构酶I抑制剂，在人类癌细胞培养中表现出明显的细胞毒性。与喜树碱相比，它们具有许多潜在的优势，包括更高的化学稳定性，更持久的裂解复合物的形成以及DNA裂解位点独特模式的诱导。分子模型表明，茚并异喹啉内酰胺氮上的取代基将从三元裂解复合物中的DNA双链体中穿过主沟突出。这表明在该位置上相对较大的取代基将被耐受而不损害生物活性。作为提高茚并异喹啉的效力和潜在治疗作用的策略，合成了一系列在内酰胺氮上含有多胺侧链的化合物。合成这些化合物的基本原理是，带正电荷的铵阳离子通过与带负电荷的DNA主链的静电结合，可以增加DNA亲和力，并且多胺还可以通过利用多胺转运蛋白来促进细胞摄取。合成中的关键步骤涉及将含有受保护胺侧链的席夫碱与取代的邻苯二甲酸酐缩合，生成顺式-3-芳基-4-羧基-1-异喹啉酮。然后将这些异喹诺酮与亚硫酰氯转化为茚并异喹啉。尽管单胺比先导化合物更有效，通过在侧
