The synthesis of four new analogues of motexafin gadolinium (MGd), a gadolinium(III) texaphyrin complex in clinical trials for its anticancer properties, is described. These new derivatives contain either 1,2-diaminobenzene or 2,3-diaminonaphthalene subunits as the source of the imine nitrogens and bear multiple 2-[2-(2-methoxyethoxy)ethoxy]ethoxy (PEG) groups, on either meso aryl or beta-pyrrolic
描述了四种新的莫他沙芬III(MGd)类似物的合成,这是一种具有抗癌特性的clinical(Ⅲ)特沙弗林复合物。这些新的衍生物含有1,2-二氨基苯或2,3-二氨基萘亚单位作为亚胺氮的来源,并且在内消旋芳基或甲基上带有多个2- [2-(2-甲氧基乙氧基)乙氧基]乙氧基(PEG)。 β-吡咯取代基,以增加其水溶性。根据使用PC3和A549细胞系的细胞增殖分析判断,发现所有四个类似物在体外均比亲本系统MGd更具活性。
