Six organotin(IV) carboxylates of the type R2SnL2 [R=CH3 (1), n-C4H9 (2), n-C8H17 (3)] and R3SnL [R=CH3 (4), n-C4H9 (5), C6H5 (6), where L=2-(4-ethoxybenzylidene) butanoic acid, have been synthesized and characterized by elemental analysis, FT-IR and NMR ((1)H, (13)C). The complex (1) was also analyzed by single crystal X-ray analysis. The complexes were screened for antimicrobial, cytotoxic and anti-tumor
R2SnL2类型的六种有机锡(IV)羧酸盐[R = CH3(1),n-C4H9(2),n-C8H17(3)]和R3SnL [R = CH3(4),n-C4H9(5),C6H5 (6),其中L = 2-(4-乙氧基亚苄基)丁酸已经合成,并通过元素分析,FT-IR和NMR((1)H,(13)C)表征。还通过单晶X射线分析法分析了配合物(1)。筛选复合物的抗微生物,细胞毒性和抗肿瘤活性。结果显示活动的每个区域都有重要活动,只有少数例外。通过UV-可见吸收光谱法和粘度测量研究了配体HL和代表性配合物2的DNA相互作用研究。结果表明,配体HL和复合物2均通过嵌入以及微小的凹槽结合而与SS-DNA相互作用。
