Heterocyclic compounds and their metal complexes display a broad spectrum of pharmacological properties. This work reports the preparation and characterization of four novel gold(I) complexes containing tertiary phosphine and 3-benzyl-1,3-thiazolidine-2-thione, 5-phenyl-1,3,4-oxadiazole-2-thione as ligands. The reaction of chloro(triphenylphosphine)gold(I) and chloro(triethylphosphine)gold(I) with
杂环化合物及其金属络合物具有广泛的药理特性。这项工作报告了四种新型金(I)配合物的制备和表征,这些配合物包含叔膦和3-苄基-1,3-噻唑烷-2-硫酮,5-苯基-1,3,4-恶二唑-2-硫酮作为配体。氯(三苯基膦)金(I)和氯(三乙基膦)金(I)与硫代酰胺,3-苄基-1,3-噻唑烷-2-硫酮和5-苯基-1,3,4-恶二唑-2的反应-硫酮在二氯甲烷或二氯甲烷/丙酮中的形成导致形成以下通式的金(I)配合物:[SAuPR 3 ] Cl,S = 3-苄基-1,3-噻唑烷-2-硫酮,R = Ph或Et和[SAuPR 3 ] ,S = 5-苯基-1,3,4-恶二唑-2-硫酮,R = Ph或Et。光谱学证据表明,在所有情况下,金都与环外硫原子配位,这一点已通过对配合物(4)的X射线晶体学数据证实。与顺铂相比,在两种不同的肿瘤细胞系结肠癌(CT26WT)和转移性皮肤黑素瘤(B16F10)中,以及在肾正常细胞
