  Synthesis of uriedo and thiouriedo derivatives of peptide conjugated heterocycles – A new class of promising antimicrobials

  摘要：

  Forty five new derivatives of ureas and thioureas were synthesized by the reaction of peptide conjugated heterocycles with isocyanates and isothiocyanates respectively. All the compounds have been characterized by IR, H-1 NMR, mass and elemental analysis. The compounds were evaluated for their ability to inhibit the growth of a panel of microorganisms and all the synthesized compounds displayed an excellent antimicrobial activity. From structure-activity relationship studies, it was apparent that thioureas infact is slightly more active than ureas. Also, substituents on the phenyl ring of the title compounds play a key role in the activity. Further, compound 40 is nearly twenty times more potent than the standard used. These results present a platform for the further studies in this line. (C) 2011 Elsevier Masson SAS. All rights reserved.

  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.
