Wood, Thomas M.;Slingerland, Cornelis J.;Martin, Nathaniel I. research published 《 A convenient chemoenzymatic preparation of chimeric macrocyclic peptide antibiotics with potent activity against gram-negative pathogens》, the research content is summarized as follows. The continuing rise of antibiotic resistance, particularly among Gram-neg. pathogens, threatens to undermine many aspects of modern medical practice. To address this threat, novel antibiotics that utilize unexploited bacterial targets are urgently needed. Over the past decade, a number of studies have highlighted the antibacterial potential of macrocyclic peptides that target Gram-neg. outer membrane proteins (OMPs). Recently, it was reported that the antibacterial activities of OMP-targeting macrocyclic peptidomimetics of the antimicrobial peptide protegrin-1 are dramatically enhanced upon linking to polymyxin E nonapeptide (PMEN). In this study, we describe a convergent, chemoenzymic route for the convenient preparation of such conjugates. Specifically, we investigated the use of both amide bond formation and azide-alkyne ligation for connecting an OMP-targeting macrocyclic peptide to a PMEN building block (obtained by enzymic degradation of polymyxin E). The conjugates obtained via both approaches display potent antibacterial activity against a range of Gram-neg. pathogens including multi-drug-resistant isolates.
73724-45-5, Fmoc-Ser-OH, also known as Fmoc-Ser-OH, is a useful research compound. Its molecular formula is C18H17NO5 and its molecular weight is 327.3 g/mol. The purity is usually 95%.
Fmoc-L-Ser-OH is a synthetic peptide that belongs to the group of glycopeptides. It is used as a model for such compounds and has been shown to have antimicrobial activity in vitro against gram-positive bacteria, especially Staphylococcus epidermidis. This compound was synthesized from 3-mercaptopropionic acid and chloride in the presence of hydroxyl groups and epidermal growth factor. The synthetic pathway can be divided into three steps: (1) condensation of 3-mercaptopropionic acid with hydrochloric acid to yield 3-mercaptoacrylic acid; (2) esterification of 3-mercaptoacrylic acid with glycine to form Fmoc-L-Ser; and (3) deprotection of Fmoc protecting group., Formula: C18H17NO5
