  Effective Methods for the Biotinylation of Azamacrocycles

  摘要：

  The biotin-(strept)avidin interaction remains a gold standard of model biological recognition events. The biotinylation of azarnacrocycles permits the investigation of signal transduction between this recognition event and the metal center of an azamacrocycle complex, of wide potential interest in biosensing. There are no generally applicable procedures in the literature for such functionalizations. We report here a comprehensive investigation into the attachment of biotin to TACN, cyclen, and cyclam.. Effective methods have been found for each ring. The efficacy of the functionalization is critically dependent on the nature of the azarnacrocycle.

• Responsive Metal Complexes: A Click-Based “Allosteric Scorpionate” Complex Permits the Detection of a Biological Recognition Event by EPR/ENDOR Spectroscopy

  Click to detect! Azamacrocyclic complexes with a triazole scorpion ligand may be easily assembled, as shown for a biotin‐functionalised cyclam derivative. Coordination of the triazole to the metal is perturbed by the binding of avidin to the pendant ligand (see scheme). This event can be sensitively detected with EPR and ENDOR spectroscopy, which confirm the loss of the axial triazole nitrogen donor

  点击检测！具有三唑蝎配体的氮杂大环配合物很容易组装，如生物素功能化的环蛋白衍生物所示。亲和素与侧基配体的结合会干扰三唑与金属的配位（请参见方案）。可以通过EPR和ENDOR光谱法灵敏地检测到此事件，这证实了抗生物素蛋白结合后轴向三唑氮供体的损失。该一般策略可能在成像和治疗中具有广泛的应用。
