  The thiopeptide (or thiostrepton) antibiotics are a class of sulfur containing highly modified cyclic peptides with interesting biological properties, including reported activity against MRSA and malaria. Described herein is the total synthesis of the thiopeptide natural product amythiamicin D, which utilizes a biosynthesis-inspired hetero-Diels-Alder route to the pyridine core of the antibiotic as

  硫肽（或硫链丝菌素）抗生素是一类含硫高度修饰的环肽，具有有趣的生物学特性，包括据报道的抗 MRSA 和疟疾活性。本文描述的是硫肽天然产物菊霉素 D 的全合成，其利用生物合成启发的杂-Diels-Alder 途径到抗生素的吡啶核心作为关键步骤。使用一系列丝氨酸衍生的 1-乙氧基-2-氮杂二烯的初步研究表明，在微波辐射下，杂-Diels-Alder 与 N-乙炔胺的反应可有效进行，得到 2,3,6-三取代的吡啶。抗生素的噻唑结构单元是通过经典的 Hantzsch 反应或通过二铑 (II) 催化的化学选择性卡宾 NH 插入，然后进行硫化而获得的，并结合得到双噻唑，形成抗生素的左侧片段。三噻唑基氮杂二烯与 2-(1-乙酰氨基乙烯基)噻唑-4-羧酸苄酯的关键 Diels-Alder 反应得到核心四噻唑基吡啶，通过连续掺入甘氨酸和双噻唑片段将其加工成天然产物通过大环化。

• RITA Mimics: Synthesis and Mechanistic Evaluation of Asymmetric Linked Trithiazoles

  The established cytotoxic agent RITA contains a thiophene-furan-thiophene backbone and two terminal alcohol groups. Herein we investigate the effect of using thiazoles as the backbone in RITA-like molecules and modifying the terminal groups of these trithiazoles, thereby generating 41 unique structures. Incorporating side chains with varied steric bulk allowed us to investigate how size and a stereocenter impacted biological activity. Subjecting compounds to growth inhibition assays on HCT-116 cells showed that the most potent compounds 7d, 7e, and 7h had GI₅₀ values of 4.4, 4.4, and 3.4 μM, respectively, versus RITA (GI₅₀ of 800 nM). Analysis of these compounds in apoptosis assays proved that 7d, 7e, and 7h were as effective as RITA at inducing apoptosis. Evaluating the impact of 7h on proteins targeted by RITA (p53, c-Myc, and Mcl-1) indicated that it acts via a different mechanism of action to that of RITA. RITA suppressed Mcl-1 protein via p53, whereas compound 7h suppressed Mcl-1 expression via an alternative mechanism independent of p53.

  DOI：10.1002/(sici)1521-4184(19999)332:9<297::aid-ardp297>3.0.co;2-#

  日期：1999.9

  2-(Pyrrolidinyl)thiazole-4-carboxylic acid 5d, 2-(1-aminoalkyl)thiazole-4-carboxamides and hydrazides 8, 10 have been synthesized using alanine, valine, and proline as educts. In addition oxazole amino acids derived from leucine 20a and alanine 20b and some peptides 13, 14, 16 containing the 5-ring heterocyclic backbone modifications have been prepared. The thiazole and oxazole containing amino acids and peptides showed moderate antibacterial activity in vitro against various Gram-positive (Staphylococcus aureus, Bacillus cereus, etc.) and Gram-negative (Escherichia coli, Proteus vulgar is, etc.) bacteria, fungi (Candida albicans), and yeast (Saccharomyces cerevisae, etc.).
