Substitution reactions of [CuI(PPh3)3X] (X = Cl, Br or I) with N,N-dimethyl-N′-phenylthiourea (dmptH), N,N-dibutyl-N′-phenylthiourea (dbptH) and 1,3-thiazolidine-2-thione (tzdtH)
摘要:
Reactions of [Cu(PPh3)3X] with the titled ligands yield [GRAPHICS] The complexes have been characterized on the basis of analytical, IR, electronic (UV-vis), H-1, P-31 and C-13 NMR, conductivity and magnetic measurements. In all cases there is a distorted tetrahedral environment around copper(I), and the ligands (LH) bind through the thione sulphur atom to copper(I).

ligand appears to influence the copper(I)-phosphine anticancer activities against the different cancer cell lines. The data suggested that complexes 2a and 2d show potential anticancer activity against prostate and breast cancers. The four copper complexes were docked against four different proteins associated with prostate or breast cancers activities, highlighting some of the structural-DNA interactions
摘要通过回流含至少四倍摩尔过量膦配体的CuBr2甲醇溶液,然后处理形成的CuBr(PR3)3配合物[ R =在DCM中具有1摩尔当量的1,10-菲咯啉的苯基(1a),4-氟苯基(1b),环己基(1c)或4-甲氧基苯基(1d)]}。三(4-甲氧基苯基)膦配体提供了[Cu(P [C6H4-4-OMe] 3)2(phen)] Br(2d)配合物,而其他膦则生成了通式为CuBr(PR3)( phen)[R =苯基(2a),4-氟苯基(2b)或环己基(2c)]。通过元素分析,31P NMR光谱和质谱法对新的配合物进行了表征。进一步确认1b,2b,通过单晶X射线衍射确定2c和2d。对配合物2a–2d与ct-DNA的DNA结合研究显示结合常数值对应于结合的嵌入模式。配合物结合常数的显着变化表明膦配体有一定的贡献。从理论上评估了复合物的亲脂性,计算出的复合物2d的log P值为正且高,处于相对较易穿透膜

atom; forming a distorted tetrahedral geometry around it. In general, Cu-L3 complex has shorter Cu-P bond lengths compared to the parent complex which suggest less steric hindrance in Cu-L3. None of the three ligands were able to use the nitrogen atoms as donating atoms due to their highly engagement in hydrogen-bonding as observed in the crystal structure of Cu-L3 as well as the theoretical calculations
茚并[1,2 - b ]喹喔啉-11-酮和肼的缩合反应衍生出一系列三个配体(L1来自肼,L2来自苯肼,L3来自硫代氨基脲)。将三种配体与CuBr(PPh 3)3在二氯甲烷中一起搅拌;没有观察到反应,只是在L3的情况下,提供了一个复杂的与式的CuBr(PPH 3)2(κ小号-L3)法(Cu-L3)。配合物的晶体结构表明,分子中的中心铜原子与两个三苯基膦基团,一个溴原子和经由[ S ]配位的茚并[1,2 - b ]喹喔啉-11-亚苄基碳硫代氨基酰肼(L3)配体配位。原子; 在其周围形成扭曲的四面体几何形状。通常,与母体复合物相比,Cu-L3复合物具有较短的Cu-P键长,这表明Cu-L3中的空间位阻较小。正如在Cu-L3的晶体结构中以及理论计算中所观察到的那样,这三个配体均不能使用氮原子作为供体原子,因为它们高度参与氢键结合。此外,理论计算表明,Cu-N相互作用弱,在超过典型键合距离的情况下,长

the different functional groups. Evaluation of the anticancer activities of the five copper compounds against two different cancer cell lines (M-14 and MCF-7) indicated the importance of the functional groups on the dppz ligand on the anticancer activities. Among the five coppercomplexes, the cyano-containing complex (Cu-3) has the best anticancer activities.
