CuL2) were prepared by reaction of Cu(CH3COO)2 with the corresponding derivatives of acylthioureas in a Cu:HL molar ratio of 1:2. Acylthiourea ligands, N,N-diethyl-N'-(R-benzoyl) thiourea (HL1-3) [R=H, o-Cl and p-NO2] were synthesized in high yield (78-83%) and characterized by elemental analysis, infrared spectroscopy, 1H and 13C NMR spectroscopy. The complexes CuL2 were characterized by elemental analysis, IR, FAB(+)-MS, magnetic susceptibility measurements, EPR and cyclic voltammetry. The crystal structure of the complex Cu(L2)2 shows a nearly square-planar geometry with two deprotonated ligands (L) coordinated to CuII through the oxygen and sulfur atoms in a cis arrangement. The antitumor activity of the copper(II) complexes with acylthiourea ligands was evaluated in vitro against the mouse mammary adenocarcinoma TA3 cell line. These complexes exhibited much higher cytotoxic activity (IC50 values in the range of 3.9-6.9 μM) than their corresponding ligands (40-240 μM), which indicates that the coordination of the chelate ligands around the CuII enhances the antitumor activity and, furthermore, this result confirmed that the participation of the nitro and chloro substituent groups in the complex activities is slightly relevant. The high accumulation of the complexes Cu(L2)2 and Cu(L3)2 in TA3 tumor cells and the much faster binding to cellular DNA than Cu(L1)2 are consistent with the in vitro cytotoxic activities found for these copper complexes."> 合成,表征和抗肿瘤活性铜(II)配合物,[CUL2] [HL1-3 = N,N-二乙基-N' - (R - 苯甲酰基)硫脲(R = H,邻Cl和P-NO 2)] - raybet雷竞app,雷竞技官网下载,雷电竞下载苹果

抽象

铜(II)配合物( CUL 2 )通过反应而制备 CH 3 COO 2 与在Cu acylthioureas的相应的衍生物:1 HL摩尔比:2。酰基硫脲配体,N,N-二乙基-N' - (R - 苯甲酰基)硫脲(HL1-3)[R = H,邻Cl和P-NO2]是在高的产率(78-83%)合成并表征通过元素分析,红外光谱,1H和13C NMR光谱学。该复合物CUL2通过元素分析进行​​表征,IR,FAB(+) - MS,磁化率测量,EPR和循环伏安法。复杂的Cu的晶体结构(L22示出了具有与Cu配位2个去质子化的配体(L)近正方形平面的几何形状II通过在一个氧原子和硫原子安排。铜的抗肿瘤活性(II)与酰基硫脲配体的络合物进行了评价体外对小鼠乳腺腺癌TA3细胞系。这些复合物表现出高得多的细胞毒性活性(IC50在3.9-6.9μM的范围比其相应的配体(40-240μM),其指示值)周围的铜的螯合配体的配位II增强的抗肿瘤活性,而且,该结果证实,硝基和氯的取代基中的复杂活动的参与是略微相关。配合物Cu的高积累(L22和Cu(L32在TA3肿瘤细胞和除了Cu快得多结合细胞DNA(L12与一致体外细胞毒活性的发现为这些铜配合物。
