  Structure−Activity Relationship Analysis of the Selective Inhibition of Transglutaminase 2 by Dihydroisoxazoles

  摘要：

  Human transglutaminase 2 (TG2) is believed to play an important role in the pathogenesis of various human disorders including celiac sprue, certain neurological diseases, and some types of cancer. Selective inhibition of TG2 should therefore enable further investigation of its role in physiology and disease and may lead to effective clinical treatment. Recently we showed that certain 3-halo-4-,5-dihydroisoxazole containing compounds are selective inhibitors of human TG2 with promising pharmacological activities. Here, we present definitive evidence that this class of compounds targets the active site of human TG2. Structure-activity relationship studies have provided insights into the structural prerequisites for selectivity and have led to the discovery of an inhibitor with about 50-fold higher activity than a prototypical dihydroisoxazole inhibitor with good in vivo activity. A method for preparing enantiomerically enriched analogues was also developed. Our studies show that the 5-(S)-dihydroisoxazole is a markedly better inhibitor of human TG2 than its 5-(R) stereoisomer.

  Single-module nonribosomal peptide synthetases (NRPSs) and NRPS-like enzymes activate and transform carboxylic acids in both primary and secondary metabolism; and are of great interest due to their biocatalytic potentials. The single-module NRPS IvoA is essential for fungal pigment biosynthesis. As disclosed herein, we show that IvoA catalyzes ATP-dependent unidirectional stereoinversion of L-tryptophan to D-tryptophan with complete conversion. While the stereoinversion is catalyzed by the epimerization (E) domain, the terminal condensation (C) domain stereoselectively hydrolyzes D-tryptophanyl-S-phosphopantetheine thioester and thus represents a noncanonical C domain function. Using IvoA, we demonstrate a biocatalytic stereoinversion/deracemization route to access a variety of substituted D-tryptophan analogs in high enantiomeric excess.

  单模块非核糖体肽合酶（NRPSs）和类NRPS酶在初级和次级代谢中激活和转化羧酸，由于其生物催化潜力，备受关注。单模块NRPS IvoA 对真菌色素生物合成至关重要。正如本文所披露的，我们展示了IvoA 催化ATP依赖的L-色氨酸向D-色氨酸的单向立体反转，实现了完全转化。虽然立体反转由外消旋（E）结构域催化，但末端缩合（C）结构域具有立体选择性地水解D-色氨酰-S-磷酰巯基丝氨酸酯，因此代表了非规范的C结构域功能。利用IvoA，我们展示了一种生物催化的立体反转/去消旋途径，以获得多种取代D-色氨酸类似物，其旋光异构体过量达到高水平。

  pure amino acid derivatives could be foundational compounds for peptide drugs. Deracemization of racemates to l-amino acid derivatives can be achieved through the reaction of evolved d-amino acid oxidase and chemical reductants, whereas deracemization to d-amino acid derivatives has not progressed due to the difficulty associated with the heterologous expression of l-amino acid oxidase (LAAO). In this

  对映体纯的氨基酸衍生物可能是肽类药物的基础化合物。外消旋物对1-氨基酸衍生物的脱硫可以通过进化出的d-氨基酸氧化酶和化学还原剂的反应来实现，而对d-氨基酸衍生物的脱硫则由于与1-氨基酸的异源表达有关的困难而没有进行。酸性氧化酶（LAAO）。在这项研究中，我们通过大肠杆菌表达系统（〜50.7 mg / L）成功开发了具有广泛的底物选择性（13 l-氨基酸）和高生产率的祖先LAAO（AncLAAO ）。AncLAAO可以应用于对d进行除权-氨基酸以类似于消旋为1-氨基酸的方式。实际上，对于16个外消旋体可以实现完全转化（＞ 99％ee，d-形式），包括九个d，1- Phe衍生物，六个d，1- Trp衍生物和d，1-苯基甘氨酸。综上所述，我们认为，AncLAAO可能是将来获得光学纯的d-氨基酸衍生物的关键酶。

  techniques to establish l‐4‐Cl‐Kyn biosynthesis, which is initiated by the flavin‐dependent tryptophan chlorinase Tar14 and its flavin reductase partner Tar15. This work revealed the first tryptophan 2,3‐dioxygenase (Tar13) and kynurenine formamidase (Tar16) enzymes that are selective for chlorinated substrates. The substrate scope of Tar13, Tar14, and Tar16 was examined and revealed intriguing promiscuity
