肽中酪氨酸残基的选择性识别是抑制其酪氨酸激酶(TK)介导的磷酸化的一种有吸引力的方法。在此,我们描述了假肽笼,有效地保护基板的Src TK酶的作用,排除相应的酪氨酸磷酸化。荧光发射滴定表明,最有效的笼抑制剂强烈结合的肽底物的结合常数和抑制效力之间有很好的相关性。结构的见解和额外的控制实验进一步支持所提出的机制的选择性超分子保护的基板。此外,该方法也适用于完全不同的激酶底物系统。这些结果说明了潜在的超分子复合物的TK信号的有效和选择性的调制。如何避免轮胎:假肽笼对酪氨酸残基的选择性识别保护底物免受Src激酶促进的磷酸化。笼的Tyr激酶抑制活性可以通过形成主客体复合物来令人满意地解释。这种超分子方法代表了通过底物识别调节Tyr激酶活性的一种有吸引力的替代方案。
The selective recognition of tyrosine residues in peptides is an appealing approach to inhibiting their tyrosine kinase (TK)‐mediated phosphorylation. Herein, we describe pseudopeptidic cages that efficiently protect substrates from the action of the Src TK enzyme, precluding the corresponding Tyr phosphorylation. Fluorescence emission titrations show that the most efficient cage inhibitors strongly bind the peptide substrates with a very good correlation between the binding constant and the inhibitory potency. Structural insights and additional control experiments further support the proposed mechanism of selective supramolecular protection of the substrates. Moreover, the approach also works in a completely different kinase‐substrate system. These results illustrate the potential of supramolecular complexes for the efficient and selective modulation of TK signaling. How to spare Tyr: The selective recognition of tyrosine residues by pseudopeptidic cages protects the substrates from Src kinase‐promoted phosphorylation. The Tyr kinase‐inhibiting activity of the cages can be satisfactorily explained by the formation of host‐guest complexes. This supramolecular approach represents an appealing alternative to modulating Tyr kinase activity by substrate recognition.
