  • Synthesis and characterization of an O6-2′-deoxyguanosine-alkyl-O6-2′-deoxyguanosine interstrand cross-link in a 5′-GNC motif and repair by human O6-alkylguanine-DNA alkyltransferase

    O6-2′-Deoxyguanosine-alkyl-O6-2′-deoxyguanosine interstrand DNA cross-links (ICLs) with a four and seven methylene linkage in a 5′-GNC- motif have been synthesized and their repair by human O6-alkylguanine-DNA alkyltransferase (hAGT) investigated. Duplexes containing 11 base-pairs with the ICLs in the center were assembled by automated DNA solid-phase synthesis using a cross-linked 2′-deoxyguanosine dimer phosphoramidite, prepared via a seven step synthesis which employed the Mitsunobu reaction to introduce the alkyl lesion at the O6 atom of guanine. Introduction of the four and seven carbon ICLs resulted in no change in duplex stability based on UV thermal denaturation experiments compared to a non-cross-linked control. Circular dichroism spectra of these ICL duplexes exhibited features of a B-form duplex, similar to the control, suggesting that these lesions induce little overall change in structure. The efficiency of repair by hAGT was examined and it was shown that hAGT repairs both ICL containing duplexes, with the heptyl ICL repaired more efficiently relative to the butyl cross-link. These results were reproducible with various hAGT mutants including one that contains a novel V148L mutation. The ICL duplexes displayed similar binding affinities to a C145S hAGT mutant compared to the unmodified duplex with the seven carbon containing ICLs displaying slightly higher binding. Experiments with CHO cells to investigate the sensitivity of these cells to busulfan and hepsulfam demonstrate that hAGT reduces the cytotoxicity of hepsulfam suggesting that the O6-2′-deoxyguanosine-alkyl-O6-2′-deoxyguanosine interstrand DNA cross-link may account for at least part of the cytotoxicity of this agent.

    Oligonucleotides containing an alkylene intrastrand cross‐link (IaCL) between the O6‐atoms of two consecutive 2′‐deoxyguanosines (dG) were prepared by solid‐phase synthesis. UV thermal denaturation studies of duplexes containing butylene and heptylene IaCL revealed a 20 °C reduction in stability compared to the unmodified duplexes. Circular dichroism profiles of these IaCL DNA duplexes exhibited signatures
    通过固相合成制备了在两个连续的2'-脱氧鸟苷(dG)的O 6原子之间包含亚烷基链内交联(IaCL)的寡核苷酸。包含丁烯和庚烯IaCL的双链体的紫外热变性研究表明,与未修饰的双链体相比,稳定性降低了20°C。这些IaCL DNA双链体的圆二色性谱显示出与B型DNA一致的特征。人O 6-烷基鸟嘌呤DNA烷基转移酶(hAGT)能够修复含有IaCL的双链体,对庚烯类似物的修复效率略高。有趣的是,与O 6相比,hAGT对这些IaCL的修复效率较低亚烷基连接的IaCL在相连的2'-脱氧鸟苷残基之间缺乏5'-3'-磷酸二酯键。这些结果表明,在dG的O 6原子处,hAGT对IaCL的活性水平受交联残基之间的主链磷酸二酯键的影响。

    A methodology to synthesize oligonucleotides containing an alkyl interstrand cross-link between the two O6 atoms of deoxyguanosine has been developed. This cross-link is designed to serve as a stable structural mimic of the lesion formed in duplex DNA with the bifunctional alkylating agent hepsulfam. The O6-alkyl coupling is performed via a Mitsunobu reaction between a nucleoside and mono-protected
