合成和表征了一系列新型的氨/环己胺铂(II)配合物,它们带有1-(取代的苄基)氮杂环丁烷-3,3-二羧酸酯作为离去基团。通过元素分析,IR,1 H NMR和ESI-MS光谱对所有配合物进行表征。已经研究了铂基化合物对几种人类癌细胞系的体外抗增殖活性,表明复合物1和11对顺铂和奥沙利铂对四种细胞系的杀伤力均相当,优于卡铂。药物安全性评估结果(急性毒性研究)显示,复合物11毒性比顺铂和奥沙利铂低得多。流式细胞仪和琼脂糖凝胶电泳研究表明,复合物1和11均诱导肿瘤细胞凋亡,并证明了复合物与pET22b质粒DNA的结合亲和力。

The present invention is directed to an improved process for synthesizing azetidine-3-carboxylic acid, comprising triflating diethylbis(hydroxymethyl)malonate followed by azetidine ring-formation by intramolecular cyclization using an amine, decarboxylation to give the mono acid azetidine and hydrogenation to give the title compound. Azetidine-3-carboxylic acid is useful as an intermediate for making certain S1P?1#191/Edg1 receptor agonists, which are immunosupressive agents.
Synthesis, antiproliferative activity and DNA binding study of mixed ammine/cyclohexylamine platinum(II) complexes with 1-(substituted benzyl) azetidine-3, 3-dicarboxylates
A novel series of ammine/cyclohexylamine platinum(II) complexes with 1-(substitutedbenzyl) azetidine-3, 3-dicarboxylates as leaving groups have been synthesized and characterized. All complexes were characterized by elemental analysis, IR, 1H NMR, and ESI-MS spectra. The in vitro antiproliferative activities of the platinum-based compounds have been investigated against several human cancer cell lines
