In continuation with our studies concerning the synthesis, characterization and biological evaluation of nucleolipidic Ru(III) complexes, a novel design for this family of potential anticancer agents is presented here. As a model compound, a new uridine-based nucleolipid has been prepared, named HoUrRu, following a simple and versatile synthetic procedure, and converted into a Ru(III) salt. Stable formulations of this highly functionalized Ru(III) complex have been obtained by co-aggregation with either the zwitterionic lipid POPC or the cationic DOTAP, which have been subjected to an in-depth microstructural characterization, including DLS, SANS and EPR measurements. The in vitro bioactivity profile of HoUrRu, as a pure compound or in formulation with POPC or DOTAP, reveals high antiproliferative activity against MCF-7 and WiDr human cancer cell lines.
为了继续研究核脂类 Ru(III)配合物的合成、表征和生物学评价,本文介绍了这一潜在抗癌剂家族的新设计。作为一种模型化合物,我们采用一种简单而多用途的合成方法制备了一种新的尿苷核脂,命名为 HoUrRu,并将其转化为 Ru(III)盐。这种高度功能化的 Ru(III) 复合物通过与齐聚离子脂质 POPC 或阳离子 DOTAP 共同聚集而获得了稳定的制剂,并对其进行了深入的微观结构表征,包括 DLS、SANS 和 EPR 测量。纯化合物或与 POPC 或 DOTAP 配制的 HoUrRu 的体外生物活性图谱显示,它对 MCF-7 和 WiDr 人类癌细胞株具有很高的抗增殖活性。
