A series of mono-, di- and triorganotin compounds with general formulae [RSnL2Cl], R = Bu (compound 3), [R2SnL2], where R = Me, Et, Bu, Oct (compounds 1, 2, 4 and 6) and [R3SnL], where R = Bu, Cy and Ph (compounds 5, 7 and 8) and where L = 3,4-methylenedioxy-6-nitrophenylpropenoic acid have been prepared and characterized by elemental analysis, multinuclear (1H-, 13C- and 119Sn-) NMR and mass spectrometry. The ligand and its respective organotin complexes were screened for cytotoxicity using the brine shrimp lethality assay and for antitumor activity using the crown gall tumor inhibition (potato disc) assay. The bioassay results support the conclusion that the biological activities of these synthetic compounds are in the following order: [RSnL2Cl] < [R2SnL2] < [R3SnL].
一系列通式为[RSnL2Cl](R = Bu)(化合物 3)、[R2SnL2](其中 R = Me、Et、Bu、Oct)(化合物 1、2、4 和 6)和[R3SnL](其中 R = Bu、Cy 和 Ph)(化合物 5、7 和 8)以及 L = 3,4-亚甲基二氧-6-硝基苯丙烯酸的单有机锡、二有机锡和三有机锡化合物,已通过元素分析、多核(1,1-二氧-6-硝基苯丙烯酸)分析和表征制备得到、L=3,4-亚甲二氧基-6-硝基苯丙烯酸),并通过元素分析、多核(1H-、13C- 和 119Sn-)核磁共振和质谱分析进行了表征。利用盐水虾致死试验对配体及其各自的有机锡配合物进行了细胞毒性筛选,并利用冠瘿肿瘤抑制(马铃薯花盘)试验对其抗肿瘤活性进行了筛选。生物测定结果支持以下结论,即这些合成化合物的生物活性按以下顺序排列:[RSnL2Cl] < [R2SnL2] < [R3SnL]。
