  Synthesis of elastin based peptides conjugated to benzisoxazole as a new class of potent antimicrobials – A novel approach to enhance biocompatibility

  摘要：

  The peptides of elastin sequences chosen for the present study included tetrapeptides, pentapeptides and tricosapeptides (30 amino acids), synthesized by classical solution phase method and conjugated to [3-(4-piperidyl)-6-fluoro-1,2-benzisoxazole]. The structures of the compounds were confirmed by physical and spectroscopic techniques followed by the antimicrobial evaluation by both agar well diffusion and microdilution methods. Here we wish to report the effect of conjugation of these moieties which enabled us to identify a novel set of peptides conjugated to heterocycle which have exhibited more potent antimicrobial activity than the conventional drugs used. Further, conjugates of tricosamers 34 and 35 were able to inhibit the growth of fungal species at 3-5 mu g/mL which is nearly 5 fold more potent than the reference drug. (C) 2010 Elsevier Masson SAS.

  Elastin protein-based polymers have their origin in repeating sequences of the mammalian elastic protein, elastin. The sequences of elastin peptides chosen are tetrapeptides, pentapeptides and tricosamers (30 amino acids) and also aromatic amino acids. These have been conjugated to 1-(2,3-dichlorophenyl)piperazine to study the effect of conjugation on the activity. The conjugates so obtained were characterized by physical and analytical techniques followed by the antimicrobial evaluation. The study revealed that all the conjugates have exhibited enhanced activity than the conventional drugs. Further, the conjugates of tricosamers have shown extraordinary activity against the fungal species with MIC value of 3–5 μg/ml which is five fold more potent than the antibiotic used.

  基于弹性蛋白（一种哺乳动物弹性蛋白）重复序列的弹性蛋白聚合物，所选择的弹性蛋白肽序列包括四肽、五肽和三十二肽（30个氨基酸），以及芳香族氨基酸。这些序列被偶联到1-(2,3-二氯苯基)哌嗪，以研究偶联对其活性的影响。所得偶联物通过物理和分析技术进行表征，随后进行抗菌评估。研究表明，所有偶联物的活性均比传统药物有所提高。此外，三十二肽的偶联物对真菌物种显示出非凡的活性，其最低抑菌浓度（MIC）值为3-5 μg/ml，比所用抗生素强五倍。

  The analogues of elastin sequences, glycyl-glycyl-alanyl-proline (GGAP), glycyl-glycyl-phenylalanyl-proline (GGFP), and glycyl-glycyl-isoleucyl-proline (GGIP) were synthesized by classical solution phase method and characterized. The kinetics of oxidation of these tetrapeptides (TETP) by Mn(III) has been studied in the presence of sulphate ions in acidic solution at 25°C. The reaction was followed
