  An unnatural amino acid based fluorescent probe for phenylalanine ammonia lyase

  摘要：

  一种基于非天然氨基酸（UAA）的荧光探针（2a-LP）被开发用于检测苯丙氨酸解氨酶（PAL）。在PAL的存在下，2a-LP被催化脱氨生成邻氨基反式肉桂酸（o-a-CA），后者表现出显著的“关闭-开启”荧光信号。因此，探针2a-LP能够在紫外光照射下直接观察番茄中PAL的活性，并具有体外检测的潜力。

  The conformationally restricted, spatially defined macrocyclic ring system of formula (I) is constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. Macrocycles described by this ring system I are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), inhibitory activity on enzymes or antimicrobial activity. In particular, these macrocycles show inhibitory activity on endothelin converting enzyme of subtype 1 (ECE-1) and/or the cysteine protease cathepsin S (CatS), and/or act as antagonists of the oxytocin (OT) receptor, thyrotropin-releasing hormone (TRH) receptor and/or leukotriene B4 (LTB4) receptor, and/or as agonists of the bombesin 3 (BB3) receptor, and/or show antimicrobial activity against at least one bacterial strain. Thus they are showing great potential as medicaments for a variety of diseases.

  公式（I）的构象受限、空间定义的大环环系统由三个不同的分子部分组成：模板A、构象调节剂B和桥C。由这种环系统I描述的大环可通过并行合成或溶液中或固相上的组合化学轻松制造。它们被设计用于与各种特定生物靶标类相互作用，例如在G蛋白偶联受体（GPCR）上的激动或拮抗活性，酶的抑制活性或抗菌活性。特别是，这些大环显示对亚型1的内皮素转化酶（ECE-1）和/或半胱氨酸蛋白酶卡特普辛S（CatS）的抑制活性，和/或作为催产素（OT）受体、促甲状腺释放激素（TRH）受体和/或白三烯B4（LTB4）受体的拮抗剂，和/或作为瘤胃素3（BB3）受体的激动剂，和/或对至少一种细菌菌株显示抗菌活性。因此，它们显示出作为各种疾病药物的巨大潜力。
