Searching for new prospective antitrypanosomal agents, three novel Ru(II)-cyclopentadienyl compounds, [Ru(η5-C5H5)(PPh3)L], with HL = bioactive 5-nitrofuryl containing thiosemicarbazones were synthesized and characterized in the solid state and in solution. The compounds were evaluated in vitro on the blood circulating trypomastigote form of Trypanosoma cruzi (Dm28c strain), the infective form of Trypanosoma
在搜索新的预期抗锥体虫剂,三种新的Ru(II)环戊二烯基化合物中,的[Ru(η 5 -C 5 H ^ 5)(PPH 3)L],用HL =含生物活性5-硝基呋喃缩氨基硫脲的合成和表征在固态并处于溶液中。化合物进行了评价在体外对血液循环的锥鞭毛体形式克氏锥虫(Dm28c株)的感染形式布氏锥虫布氏(菌株427)和J774小鼠巨噬细胞和人衍生的将EA.hy926内皮细胞。该化合物对两种寄生虫均具有IC 50活性值在微摩尔或亚微摩尔范围内。有趣的是,它们比以前开发的具有相同生物活性配体的Ru(II)古典和有机金属化合物对克鲁维酵母具有更高的活性。新化合物对哺乳动物细胞显示出对寄生虫的中等至非常好的选择性。全球结果指向[RuCp(PPh 3)L2](L2 = 含5-硝基呋喃基的硫代半脲的N-甲基衍生物,Cp =环戊二烯基)是进一步发展的最有希望的化合物(IC 50 T. cruzi = 0.41μM;
