The synthesis of complexes PtCl2(L2) of some bidentate ligands (L2) containing pyridyl rings connected by a carbon atom, di-2-pyridylmethane (py2CH2) and py2SEt2, and containing both pyridyl and imidazolyl rings, (2,2’-pyridyl)imidazole (pyIm) and py-NMeIm. Preliminary screening of the complexes, including the 2,2’-bipyridyl complex and cis-PtL2Cl2 (L = NH3, pyridine), on cultures of L1210 mouse leukemia
某些二齿配体(L2)的配合物PtCl2(L2)的合成,该配体含有通过碳原子连接的吡啶基环,二-2-吡啶基甲烷(py2CH2)和py2SEt2,并且同时具有吡啶基和咪唑基环,(2,2'-吡啶基咪唑(pyIm)和py-NMeIm。已经对L1210小鼠白血病细胞培养物中的复合物进行了初步筛选,包括2,2'-联吡啶复合物和顺式-PtL2Cl2(L = NH3,吡啶)。在给出低至90%的生长抑制所需的浓度范围内获得结果,并获得了预期的S形曲线(生长百分比与浓度的关系)。顺式-Pt(吡啶)2Cl2复合物的ID50值高于顺式-Pt(NH3)2C12,与早期研究一致,该研究表明该复合物对小鼠的艾氏腹水和肉瘤180肿瘤具有比顺式-Pt(NH3)2Cl2更低的活性。复数Pt(pyIm)C12。H 2 O的ID 50值类似于顺式Pt(NH 3)2 Cl 2,并且低于其他配合物的ID 50值。这些结果表明,对携带
