    Synthesis and Structure of the Group 12 Pyrimidinethiolate Complexes 3 [Zn(S‐2‐N 2 C 4 H 3 ) 2 ], 2 [Cd(S‐2‐N 2 C 4 H 3 ) 2 ], [Hg(S‐2‐N 2 C 4 H 3 ) 2 ] and[Cd(S‐2‐N 2 C 4 H 3 ) 2 (tmeda)]
    摘要:
    AbstractThe pyrimidinethiolate complexes 3[Zn(S‐2‐N2C4H3)2],2[Cd(S‐2‐N2C4H3)2] and [Hg(S‐2‐N2C4H3)2] have been prepared by reaction of MCl2 (M = Zn, Cd, Hg) with 2 equiv. of Me3SiS‐2‐N2C4H3 in organic solvents, whilst [Cd(S‐2‐N2C4H3)2(tmeda)] was obtained by recrystallisation of2[Cd(S‐2‐N2C4H3)2] in TMEDA at 40 °C. The structures of the complexes were determined by single‐crystal X‐ray crystallography, which shows that the different metal atoms each have different coordination environments. The zinc atom in 3[Zn(S‐2‐N2C4H3)2] exhibits a tetrahedral coordination with one sulfur and three nitrogen atoms from pyrimidinethiolate ligands, whereas the cadmium atoms in 2[Cd(S‐2‐N2C4H3)2] and [Cd(S‐2‐N2C4H3)2(tmeda)] are six‐coordinate with either three sulfur and three nitrogen atoms or two sulfur and four nitrogen atoms. In contrast, the mercury atoms in [Hg(S‐2‐N2C4H3)2] display a distorted square‐planar coordination to a pair of chelating S‐2‐N2C4H3 ligands with additional weak Hg–S interactions to adjacent molecules. While known cadmium and zinc pyrimidinethiolate complexes consist of one‐dimensional chains, 3[Zn(S‐2‐N2C4H3)2] and 2[Cd(S‐2‐N2C4H3)2] form either three‐ or two‐dimensional polymeric networks of metal atoms.

    2-Thiozebularine: base modified nucleoside fully constrained in C3′-endo conformation in solution
    摘要:
    2-硫代嘧啶核糖苷(2-thiozebularine,s2zeb)是通过采用硅基N-糖苷键形成的方法,并利用Lawesson试剂对保护的2-氧代核苷衍生物(zebularine,zeb)进行硫化而合成的。将s2zeb的X射线晶体结构和NMR测定的s2zeb和zeb在溶液中的构象与2-硫代尿苷(s2U)和尿苷(U)的结构进行了比较。在固态中,s2zeb分子采用核糖核苷酸的典型构象:C3'-内旋C2'-外旋的核糖环扭曲类型,N-糖苷键为反式,C4'-C5'之间为顺式。然而,在水溶液中,几乎100%的s2zeb呈现C3'-内旋的核糖环扭曲类型。s2zeb的N构象的种群比zeb高约20%(类似于s2U和U核苷的一对),表明巨大的硫原子对N型核糖构象的稳定具有类似的立体效应。有趣的是,zeb和s2zeb中缺少的4-羰基功能使C3'-内旋构象的种群比U和s2U高约30%,这是由于显著的异构效应。两种效应的加成使得2-硫代嘧啶核糖苷在水溶液中几乎完全限制在C3'-内旋构象中。s2zeb的细胞毒性性质比zebularine要稍弱,对HeLa和K562癌细胞以及HUVEC非癌细胞的IC50> 100 mM。
