Abstract
AbstractOxymaPure [ethyl 2-cyano-2-(hydroxyimino)acetate] is an exceptional reagent with which to suppress racemization and enhance coupling efficiency during amide bond formation. The tremendous popularity of OxymaPure has led to the development of several Oxyma-based reagents. OxymaPure and its derived reagents are widely used in solid- and solution-phase peptide chemistry. This review summarizes the recent developments and applications of OxymaPure and Oxyma-based reagents in peptide chemistry, in particular in solution-phase chemistry. Moreover, the side reaction associated with OxymaPure is also discussed.1 Introduction2 Oxyma-Based Coupling Reagents2.1 Aminium/Uronium Salts of OxymaPure2.2 Phosphonium Salts of OxymaPure2.3 Oxyma-Based Phosphates2.4 Sulfonate Esters of OxymaPure2.5 Benzoate Esters of OxymaPure2.6 Carbonates of OxymaPure Derivatives3 OxymaPure Derivatives4 Other Oxime-Based Additives and Coupling Reagents5 Side Reactions Using OxymaPure Derivatives6 Conclusion7 List of Abbreviations

An optimised series of substituted N-phenylpyrrolamides as DNA gyrase B inhibitors. Eur J Med Chem 2019; 167:269-290. [PMID: 30776691 DOI: 10.1016/j.ejmech.2019.02.004] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Revised: 01/18/2019] [Accepted: 02/01/2019] [Indexed: 10/27/2022]
Abstract
ATP competitive inhibitors of DNA gyrase and topoisomerase IV have great therapeutic potential, but none of the described synthetic compounds has so far reached the market. To optimise the activities and physicochemical properties of our previously reported N-phenylpyrrolamide inhibitors, we have synthesized an improved, chemically variegated selection of compounds and evaluated them against DNA gyrase and topoisomerase IV enzymes, and against selected Gram-positive and Gram-negative bacteria. The most potent compound displayed IC50 values of 6.9 nM against Escherichia coli DNA gyrase and 960 nM against Staphylococcus aureus topoisomerase IV. Several compounds displayed minimum inhibitory concentrations (MICs) against Gram-positive strains in the 1-50 μM range, one of which inhibited the growth of Enterococcus faecalis, Enterococcus faecium, S. aureus and Streptococcus pyogenes with MIC values of 1.56 μM, 1.56 μM, 0.78 μM and 0.72 μM, respectively. This compound has been investigated further on methicillin-resistant S. aureus (MRSA) and on ciprofloxacin non-susceptible and extremely drug resistant strain of S. aureus (MRSA VISA). It exhibited the MIC value of 2.5 μM on both strains, and MIC value of 32 μM against MRSA in the presence of inactivated human blood serum. Further studies are needed to confirm its mode of action.

Abstract
Taurine-containing water-soluble peptidomimetics were designed and synthesized. N-terminal taurine acylations allowed synthesis of a number of taurine-containing peptides. N-protection of taurine with Cbz and SO2-activation with benzotriazole followed by coupling with various amino esters, dipeptides and nucleophiles provided taurine N- and O-conjugates and sulfonopeptides.
