with N-(acyl)-N′,N′-(disubstituted) thioureas and phosphine ligands were synthesized and characterized by FT-IR, multinuclear (1H, 13C & 31P) NMR spectroscopy and elemental analysis. The crystal structures of the Pd(II) complexes (1) & (5) of the type PdII(L-O,S)(Ĺ-P)Cl were determined by single crystal X-ray diffraction analysis. They adopted the square planar geometry, where the N-(acyl)-N′, N′-(disubstituted)
摘要合成了一系列具有N-(酰基)-N',N'-(二取代)硫脲和膦配体的钯(II)配合物(1-8),并通过FT-IR,多核(1H,13C和31P)进行了表征)NMR光谱和元素分析。通过单晶X射线衍射分析确定PdII(LO,S)(α-P)Cl型Pd(II)配合物(1)和(5)的晶体结构。他们采用正方形平面几何结构,其中N-(酰基)-N',N'-(二取代)硫脲通过螯合方式通过O和S供体原子显示二齿配位模式,并通过P原子在钯中心显示膦配体。测定了合成的钯(II)配合物(1-8)对肺鳞癌和乳腺癌细胞的体外细胞毒性谱。还测试了这些复合物是否为热带利什曼原虫的前鞭毛体形式,以评估其抗疟原虫活性。在筛选的复合物中,带有2,4-二氯苯基部分的复合物活性最高,分别针对目标MDA-MB-231,H-157和热带利什曼原虫的IC50值为1.72±0.27、2.12±0.44、1.57±0.16 µM。
