EPR和共振拉曼的差异与Fe 3 +BLM聚 d(CG)与poly d(AT)相比。 Fe3+ BLM的多种构象 在缓冲液中和药物结合poly d(AT)时观察到。 收窄 EPR吸收衍生物在结合到d(CG)或 DNA代表特定的相互作用,如共振所示 拉曼。 提出了一个模型,表明CG的药物识别 位点需要从氨基形成特定的氢键, 将BLM的嘧啶转化为碱基d(CG)。 写了一篇论文, 描述这项工作。
英文摘要
EPR and resonance Raman differences are seen with Fe3+BLM poly d(CG) as compared to poly d(AT). Multiple conformers of the Fe3+ BLM are seen in buffer and when the drug binds poly d(AT). Narrowing of features of the EPR absorption derivative upon binding to d(CG) or to DNA speak for specific interaction, as demonstrated by resonance Raman. A model is presented suggesting that drug recognition of CG sites entails the formation of a specific hydrogen bond from the amino pyrimidine of BLM to a base d(CG). A paper has been written and submitted describing this work.
