conformationally switched by light. An amino acid analogue was designed and synthesized based on a reversibly photoisomerizable diarylethene scaffold. This analogue was incorporated into the cyclic backbone of the antimicrobial peptide gramicidin S at several sites. The biological activity of the resulting peptidomimetics could then be effectively controlled by ultraviolet/visible light within strictly defined
自然界中的光生物学过程通常由非肽发色团或修饰的侧链触发。提出了一种系统,其中多肽骨架本身可以通过光进行构象转换。基于可光异构化的二芳基乙烯支架,设计并合成了氨基酸类似物。将该类似物在几个位点掺入抗微生物肽短杆菌肽S的环状骨架中。然后,可以在严格定义的空间和时间范围内,通过紫外线/可见光有效控制所得拟肽的生物活性。
