Syntheses and Characterizations of Two New Cadmium Complexes Based on Oxalate
Ming-San Miao,Bo-Lin Cheng,Zhen Liang,Huai-Xia Yang,Xiang-Ru Meng 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.9
Two new Cd(II) complexes, {[Cd(COO)2]2·2H2O}n (1) and {[CdCl(COO)2(Hbmi)]·H2O} n (2), were obtained through the reactions of oxalic acid (H2ox) with CdCl2 ·2.5H2O in the presence of 1-[(benzoimidazol-yl)methyl]-1H-tetrazole (bmt) or 1-[(benzoimidazol-yl)methyl]-1H-imidazol (bmi). Single-crystal X-ray diffraction shows that complex 1 has a 3-D structure with the topological notation of (48 · 62)(46 · 66 · 83)(42 · 84), in which the oxalate displays two kinds of coordination modes: formation of the layers (μ6-ox) and linking the layers (μ4-ox). In complex 2, oxalates bridge Cd(II) ions, forming a 1-D chain, and (Hbmi)+ cations coordinate to the Cd(II) ions in monodentate mode and hang at two sides of the main chain. This indicates that subtle modification of the N-donor ligands can result in complexes with different compositions and architectures. Moreover, their IR spectra, PXRD (powder X-ray diffraction) patterns, thermogravimetric analyses, and fluorescence properties are also investigated.

Aim: To investigate whether XRCC1 and ADPRT polymorphisms might be associated with outcomes of breast cancer. Methods: A prospective study was conducted with a total of 335 breast cancer patients undergoing chemotherapy consecutively collected from Jan. 2005 to Jan. 2008. Genotyping of XRCC1 and ADPRT polymorphisms was conducted by PCR-RFLP assay. Results: All 335 patients were followed up until death or the end of Jan. 2012, with a median follow-up period of 38.8 (2-64) months. It was shown that the variant genotype of XRCC1 399Gln/Gln was strongly significantly associated with a decreased risk of death from breast cancer, with an HR (95% CI) of 0.52 (0.28-0.91). Similarly, individuals carrying the ADPRT 762Ala/Ala demonstrated longer survival compared to ADPRT 762 Val/Val, with an HR (95% CI) of 0.58 (0.31-0.97). Individuals with combination genotypes of XRCC1 399Gln allele and ADPRT 762Ala/Ala presented with a longer survival, the HR (95% CI) being 0.56 (0.32-0.97). Conclusion: We found a significant association between XRCC1399Gln/Gln and ADPRT 762Ala/Ala polymorphisms and clinical outcomes. These two genotypes could be used as a surrogate markers of clinical outcome in glioma cases receiving chemotherapy.
