  Asymmetric Syntheses of Protected Derivatives of Carnosadine and Its Stereoisomers as Conformationally Constrained Surrogates for Arginine

  摘要：

  All four stereoisomers of carnosadine were shown to be accessible from the lactone 1 or the diester 10 (or their enantiomers). Members of the cis series (Z-cyclo-Arg') were obtained via a sequence involving opening lactone 1 with ammonia, Hofmann rearrangement, and incorporation of the guanidine group via an azide (3). The trans series (i.e. The E-cyclo-Arg' series) was prepared via a route which is similar, except that it begins with hydrolysis of the less hindered ester functionality of diester 10. Products from both series were manipulated into protected forms for peptide synthesis using the BOC or the FMOC approach.

  A novel lipopeptide antibiotic, stalobacin I (1), was discovered from a culture broth of an unidentified Gram-negative bacterium. Stalobacin I (1) had a unique chemical architecture composed of an upper and a lower half peptide sequence, which were linked via a hemiaminal methylene moiety. The sequence of 1 contained an unusual amino acid, carnosadine, 3,4-dihydroxyariginine, 3-hydroxyisoleucine, and

  从未知革兰氏阴性细菌的培养液中发现了一种新的脂肽抗生素司他巴星I（1）。Stalobacin I（1）具有独特的化学结构，该结构由上半部分和下半部分肽序列组成，它们通过半胱氨酸亚甲基部分相连。1的序列包含一个不寻常的氨基酸，卡诺萨丁，3,4-二羟基精氨酸，3-羟基异亮氨酸和3-羟基天冬氨酸，以及一种新型的环丙基脂肪酸。1对多种耐药革兰氏阳性细菌的抗菌活性比万古霉素，利奈唑胺和特拉万星（MIC 0.004-0.016μg/ mL）等“最后使用”的抗生素要强得多。此外，化合物1通过膨胀细菌细胞体诱导革兰氏阳性和革兰氏阴性菌株的特征形态变化。通过对其立体异构体的合成研究，确定了环丙基氨基酸卡诺沙丁的绝对构型，这是1的强活性必不可少的组成部分。
