In this work we reported the synthesis and evaluation of Mycobacterium tuberculosis activities in vitro of a series of twenty five ferrocenyl derivatives: ferrocenyl amides derived from nicotinamide and pyrazinamide, ferrocenyl pyridinyl, quinolyl and acridinylhydrazones. In particular ferrocenyl acylhydrazones 7 and 8 and ferrocenylquinoxaline amide 57(More)
A method for the characterization of proteins separated by isoelectric focusing in carrier ampholytes (CA-IEF) or immobilized pH gradient (IPG) gels by in-gel digestion and mass spectrometry is described. Proteins are detected by an improved imidazole-Sodium dodecyl sulfate (SDS)-zinc staining adapted for IEF and IPG gels. Sensitivity is close to that of(More)
Peptide-protein conjugates are useful tools in different fields of research as, for instance, the development of vaccines and drugs or for studying biological mechanisms, to cite only few applications. N-Succinimidyl carbamate (NSC) chemistry has been scarcely used in this area. We show that unprotected peptides, featuring one lysine residue within their(More)
The design of novel methods giving access to peptide alkylthioesters, the key building blocks for protein synthesis using Native Chemical Ligation, is an important area of research. Bis(2-sulfanylethyl)amido peptides (SEA peptides) 1 equilibrate in aqueous solution with S-2-(2-mercaptoethylamino)ethyl thioester peptides 2 through an N,S-acyl shift(More)
In this report, we present the characterization of a humanized monoclonal antibody specific for the human epidermal growth factor receptor (hEGFR). Direct analysis by matrix assisted laser desorption ionization mass spectrometry (MALDI-MS) of peptide mixtures and chromatographically isolated fractions allowed identification of 94.0% and 85.4% of the amino(More)
Protein chemical synthesis by native peptide ligation of unprotected peptide segments is an interesting complement and potential alternative to the use of living systems for producing proteins. Actually, tremendous efforts are focused on the design of one-pot strategies allowing the assembly of three peptide segments. The goal is to get rapid access to(More)
