Searching for prospective agents against infectious diseases, four new ferrocenyl derivatives, [M(L)(dppf)4](PF6), with M = Pd(II) or Pt(II), dppf = 1,1′-bis(dipheny1phosphino) ferrocene and HL = tropolone (HTrop) or hinokitiol (HHino), were synthesized and characterized. Complexes and ligands were evaluated against the bloodstream form of T. brucei, L. infantum amastigotes, M. tuberculosis (MTB) sensitive
寻找抗传染病的前瞻性药物,四种新的二茂铁基衍生物[M(L)(dppf)4](PF 6),其中M = Pd(II)或Pt(II),dppf = 1,1'-bis(合成并表征了二苯基膦基二茂铁和HL =对苯二酚(HTrop)或扁柏酚(HHino)。复合物和配体对的血流形式进行评价布氏锥虫,婴儿利什曼原虫的无鞭毛体,结核分枝杆菌(MTB)敏感菌株和MTB临床分离株。相对于游离配体,复合物显示出抗布鲁氏杆菌的活性显着提高(分别与Pt-dppf和Pd-dppf配位的Trop的> 28-和> 46倍,Hino的6-和22-倍) ),产生IC 50值<5μM。事实证明,该复合物比抗锥虫药Nifurtimox更有效。新的二茂铁基衍生物对寄生虫的选择性高于游离配体。Pt化合物对J774鼠巨噬细胞(哺乳动物细胞模型)的毒性小于Pd化合物,显示高达23的选择性指数值(SI = IC 50鼠巨噬细胞/ IC 50
