  • Synthesis of libraries of thiazole, oxazole and imidazole-based cyclic peptides from azole-based amino acids. A new synthetic approach to bistratamides and didmolamides
    作者:Anna Bertram、Nakia Maulucci、Olivia M. New、Siti Mariam Mohd Nor、Gerald Pattenden
    DOI:10.1039/b701999h
    日期:——
    Treatment of a 1 : 1 mixture of the thiazole-based amino acids 8a and 8b with FDPP–i-Pr2NEt in CH3CN gave a mixture of the cyclic trimers 14, 15, 16 and 17 and the cyclic tetramers 19 and 23 in the ratio 2 : 7 : 5 : 8 : 1 : 1 and in a combined yield of 70%. Separate coupling reactions between the bisimidazole amino acid 45 and the thiazole/oxazole amino acids 43a and 42a in the presence of FDPP–i-Pr2NEt led to the bisimidazole based cyclic trimers 55 and 57 respectively (54–57%) and to the cyclic tetramer 56 (8–11%). Similar coupling reactions involving the bisthiazole and bisoxazole amino acids 49 and 47 with the imidazole/oxazole/thiazole amino acids 41a, 42a and 43a gave rise to the library of oxazole, thiazole and imidazole-based cyclic peptides 58, 59, 60, 61, 62, 63, 64 and 65. A coupling reaction between the bisthiazole amino acid 49 and the oxazole amino acid 73 led to an efficient (36% overall) synthesis of bistratamide H (67) found in the ascidian Lissoclinum bistratum. Coupling reactions involving oxazolines with thiazole amino acids were less successful. Thus, a coupling reaction between the phenylalanine-based oxazoline amino acid 71a and either the thiazole amino acid 8a or the bisthiazole amino acid 74 gave only a 2% yield of the cyclic hexapeptide didmolamide A (4) found in the ascidian Didemnum molle. Didmolamide B (68) was obtained in 9% yield from a coupling reaction between 74 and the phenylalanine threonine amino acid 72, using either FDPP or DPPA.
    噻唑氨基酸8a和8b的1:1混合物与FDPP-i-Pr2NEt在CH3CN中处理,得到了环状三聚体14、15、16和17以及环状四聚体19和23的混合物,其比例为2:7:5:8:1:1,总产率为70%。在FDPP-i-Pr2NEt存在下,双咪唑氨基酸45与噻唑/噁唑氨基酸43a和42a分别进行的单独偶联反应,分别得到了双咪唑基环状三聚体55和57(产率54-57%)以及环状四聚体56(产率8-11%)。类似地,双噻唑和双噁唑氨基酸49和47与咪唑/噁唑/噻唑氨基酸41a、42a和43a进行的偶联反应,生成了噁唑噻唑咪唑基环状肽库58、59、60、61、62、63、64和65。双噻唑氨基酸49与噁唑氨基酸73之间的偶联反应,高效(总产率36%)合成了在海鞘Lissoclinum bistratum中发现的双层板H(67)。含有噻唑氨基酸噁唑啉的偶联反应效果较差。因此,苯丙酸基噁唑氨基酸71a与噻唑氨基酸8a或双噻唑氨基酸74之间的偶联反应,仅得到了在海鞘Didemnum molle中发现的环状六肽didmolamide A(4),产率仅为2%。使用FDPPDPPA,从74与苯丙酸苏氨基酸72的偶联反应中获得了产率为9%的didmolamide B(68)。
  • Late-Stage Macrocyclization of Bioactive Peptides with Internal Oxazole Motifs via Palladium-Catalyzed C–H Olefination

    the synthesis and direct functionalization of complex oxazole-containing peptides are in high demand. Herein, we report the late-stage site-selective functionalization of oxazole-containing peptides via palladium-catalyzed δ-C(sp2)–H olefination of phenylalanine, tryptophan, and tyrosine residues. This strategy utilizes oxazole motifs as internal directing groups and provides access to oxazole-containing
    恶唑是一种重要的药效团,存在于许多生物活性肽天然产物肽模拟物的骨架中。对复杂的含恶唑肽的合成和直接功能化的有效方法有很高的需求。在此,我们报告了通过催化的苯丙酸、色酸和酪氨酸残基的δ-C(sp 2 )-H 烯化作用对含恶唑肽进行后期位点选择性功能化。该策略利用恶唑基序作为内部导向基团,并提供了获得具有生物活性的含恶唑肽大环化合物的途径。
  • Thiopeptide Pyridine Synthase TbtD Catalyzes an Intermolecular Formal Aza-Diels–Alder Reaction
    作者:Jonathan W. Bogart、Albert A. Bowers
    DOI:10.1021/jacs.8b11852
    日期:2019.2.6
    Thiopeptide pyridine synthases catalyze a multistep reaction involving a unique and nonspontaneous intramolecular aza-[4 + 2] cycloaddition between two dehydroalanines to forge a trisubstituted pyridine core. We discovered that the in vitro activity of pyridine synthases from the thiocillin and thiomuracin pathways are significantly enhanced by general base catalysis and that this broadly expands the
    吡啶合酶催化多步反应,包括两个脱氢丙酸之间独特且非自发的分子内氮杂-[4 + 2] 环加成,以形成三取代的吡啶核心。我们发现来自西林和胞嘧啶途径的吡啶合酶的体外活性通过一般碱催化显着增强,并且这广泛地扩展了酶的底物耐受性。值得注意的是,除了其同源的分子内反应之外,TbtD 还能够进行分子间环化,这突显了其作为生物催化剂的多功能性。这些数据提供了吡啶合酶使用双位点底物识别模型来接合和处理其底物的证据。
  • Synthesis and preliminary antibacterial evaluation of hydroxamic acid and N-formyl hydroxylamine derivatives bearing oxazole ring
    作者:Datong Zhang、Lingyan Huo、Laichun Lu、Qiong Yu、Jianwu Wang、Yanyan Yang
    DOI:10.1007/s00044-012-0141-8
    日期:2013.3
    Three hydroxamic acids and seven N-formyl hydroxylamine derivatives containing oxazole ring have been designed and synthesized. The structures of target compounds were characterized on the basis of spectral (FT-IR, 1H NMR, and HRMS) analysis. All the final synthesized compounds were evaluated in vitro against Staphylococcus aureus, Streptococcus pneumonia, Escherichia coli, and Pseudomonas aeruginosa
