  • The Reaction of Alkyl Halides with Mercuric Thiocyanate in Tetrahydrofuran. The Solvent Incorporation and the Intermediacy of<i>O</i>-Alkyltetrahydrofuranram Ions.
    作者:Nanao Watanabe、Sakae Uemura、Masaya Okano
    DOI:10.1246/bcsj.48.3205
    日期:1975.11
    The reaction of alkyl halides with mercuric thiocyanate in tetrahydrofuran (THF) affords mainly the THF-incorporated products, R[O(CH2)4]nNCS and R[O(CH2)4]nSCN (mostly n=1 and 2), where the isomer ratios (N/S ratios) are nearly 1. The reaction of EtO(CH2)mBr (m=2–5) with mercuric thiocyanate in THF or n-Bu2O proceeds rapidly only in the case of m=4 to give EtO(CH2)4NCS and EtO(CH2)4SCN, the N/S ratio
    卤代烷与硫氰酸汞在四氢呋喃 (THF) 中的反应主要提供了包含 THF 的产物 R[O(CH2)4]nNCS 和 R[O(CH2)4]nSCN(主要是 n=1 和 2),其中异构体比率(N/S 比率)接近 1。 EtO(CH2)mBr (m=2–5) 与硫氰酸汞在 THF 或 n-Bu2O 中的反应仅在 m=4 的情况下快速进行,生成 EtO (CH2)4NCS 和 EtO(CH2)4SCN,N/S 比也接近 1,当 m=5 时得到 EtNCS 和 EtSCN,而硫氰酸钾在 DMF 中的反应提供了良好的 EtO(CH2)mSCN ( m=2–5) 几乎是唯一的产品。这表明标题反应涉及五元氧鎓离子、O-烷基四氢呋喃离子的初始形成,以及随后 XHg(SCN)2- 的攻击。
  • O4-Alkyl-2′-deoxythymidine cross-linked DNA to probe recognition and repair by O6-alkylguanine DNA alkyltransferases
    作者:Francis P. McManus、Derek K. O'Flaherty、Anne M. Noronha、Christopher J. Wilds

    DNA duplexes containing a directly opposed O4-2′-deoxythymidine-alkyl-O4-2′-deoxythymidine (O4-dT-alkyl-O4-dT) interstrand cross-link (ICL) have been prepared by the synthesis of cross-linked nucleoside dimers which were converted to phosphoramidites to produce site specific ICL. ICL duplexes containing alkyl chains of four and seven methylene groups were prepared and characterized by mass spectrometry and nuclease digests. Thermal denaturation experiments revealed four and seven methylene containing ICL increased the Tm of the duplex with respect to the non-cross-linked control with an observed decrease in enthalpy based on thermodynamic analysis of the denaturation curves. Circular dichroism experiments on the ICL duplexes indicated minimal difference from B-form DNA structure. These ICL were used for DNA repair studies with O6-alkylguanine DNA alkyltransferase (AGT) proteins from human (hAGT) and E. coli (Ada-C and OGT), whose purpose is to remove O6-alkylguanine and in some cases O4-alkylthymine lesions. It has been previously shown that hAGT can repair O6-2′-deoxyguanosine-alkyl-O6-2′-deoxyguanosine ICL. The O4-dT-alkyl-O4-dT ICL prepared in this study were found to evade repair by hAGT, OGT and Ada-C. Electromobility shift assay (EMSA) results indicated that the absence of any repair by hAGT was not a result of binding. OGT was the only AGT to show activity in the repair of oligonucleotides containing the mono-adducts O4-butyl-4-ol-2′-deoxythymidine and O4-heptyl-7-ol-2′-deoxythymidine. Binding experiments conducted with hAGT demonstrated that the protein bound O4-alkylthymine lesions with similar affinities to O6-methylguanine, which hAGT repairs efficiently, suggesting the lack of O4-alkylthymine repair by hAGT is not a function of recognition.
    通过合成交联核苷二聚体制备了含有直接对立的 O4-2â²-脱氧胸苷-烷基-O4-2â²-脱氧胸苷(O4-dT-烷基-O4-dT)链间交联(ICL)的 DNA 双链体。制备了含有四个和七个亚甲基的烷基链的 ICL 双链体,并通过质谱分析和核酸酶消化进行了表征。热变性实验表明,与未交联的对照组相比,含有四个和七个亚甲基的 ICL 提高了双链体的 Tm 值,根据变性曲线的热力学分析,焓值也有所降低。对 ICL 双链体进行的环二色性实验表明,它们与 B 型 DNA 结构的差异极小。这些 ICL 被用来与来自人类(hAGT)和大肠杆菌(Ada-C 和 OGT)的 O6-烷基鸟嘌呤 DNA 烷基转移酶(AGT)蛋白一起进行 DNA 修复研究。以前的研究表明,hAGT 可以修复 O6-2â²-脱氧鸟苷-烷基-O6-2â²-脱氧鸟苷 ICL。本研究中制备的 O4-dT-alkyl-O4-dT ICL 可逃避 hAGT、OGT 和 Ada-C 的修复。电迁移试验(EMSA)结果表明,hAGT 没有进行任何修复并不是因为结合的结果。在修复含有 O4-丁基-4-醇-2â²-脱氧胸苷和 O4-庚基-7-醇-2â²-脱氧胸苷的寡核苷酸时,OGT 是唯一显示出活性的 AGT。用 hAGT 进行的结合实验表明,该蛋白结合 O4-烷基胸腺嘧啶病变的亲和力与 hAGT 能有效修复的 O6-甲基鸟嘌呤相似,这表明 hAGT 缺乏对 O4-烷基胸腺嘧啶的修复功能并不是识别功能的问题。

    N-confused porphyrin, (NCPH)H2 (1), and N-fused porphyrin, (NFP)H (2). The reaction of dichlorophenylborane and 1 yields sigma-phenylboron N-confused porphyrin (4). The boron atom is bound by two pyrrolic nitrogen atoms and the sigma-phenyl ligand. The N-confused pyrrole ring is not involved in the direct coordination because the C(21)-H fragment remains intact. A reaction between PhBCl2 and N-fused porphyrin
    硼(III)已插入与N稠合的卟啉(NCPH)H2(1)和与N稠合的卟啉(NFP)H(2)中。二氯苯基硼烷与1的反应生成σ-苯基硼N稠合的卟啉(4)。硼原子由两个吡咯氮原子和sigma-苯基配体键合。N混淆的吡咯环不参与直接配位,因为C(21)-H片段保持完整。PhBCl2与N稠合的卟啉之间的反应产生sigma-苯基硼N稠合的卟啉(3+)。4在质子化下定量转化为3+。在σ-苯基硼N稠合的卟啉[(NFP)BPh] Cl中,硼(III)的配位环境类似于扭曲的三角锥,氮原子占据赤道位置,苯基配体位于独特的顶点。硼(III)与N3平面的距离为0.547(4)A。BN距离如下:BN(22),1.559(4)A; BN(23),1.552(4)A; BN(24),1.568(4)A; BC(ipsoPh),1.621(4)A.考虑到填充的八位字节和完整的配位域,3+可以归为硼阳离子。3+易于在内部C(9
