Unnatural amino acids increase activity and specificity of synthetic substrates for human and malarial cathepsin C
Mammalian cathepsin C is primarily responsible for the removal of N-terminal dipeptides and activation of several serine proteases in inflammatory or immune cells, while its malarial parasite… Expand
alpha-Aminoalkylphosphonates as a tool in experimental optimisation of P1 side chain shape of potential inhibitors in S1 pocket of leucine- and neutral aminopeptidases.
The synthesis and biological activity studies of the series of structurally different alpha-aminoalkylphosphonates were performed in order to optimise the shape of the side chain of the potential… Expand
α‐Aminoalkylphosphonates as a Tool in Experimental Optimisation of P1 Side Chain Shape of Potential Inhibitors in S1 Pocket of Leucine‐ and Neutral Aminopeptidases.
A synthetic method for diversification of the P1' substituent in phosphinic dipeptides as a tool for exploration of the specificity of the S1' binding pockets of leucine aminopeptidases.
A novel, general, and versatile method of diversification of the P1' position in phosphinic pseudodipeptides, presumable inhibitors of proteolytic enzymes, was elaborated. The procedure was based on… Expand
Individual stereoisomers of phosphinic dipeptide inhibitor of leucine aminopeptidase.
Individual stereoisomers of the phosphinic pseudodipeptide hPhepsi[P(O)(OH)CH(2)]Phe were obtained by stereoselective liquid chromatographic separation as N- and C-terminally protected derivative on… Expand
Stereoselective synthesis of 1-aminoalkanephosphonic acids with two chiral centers and their activity towards leucine aminopeptidase.
The stereoselective synthesis of 1-amino-2-alkylalkanephosphonic acids, namely, compounds bearing two chiral centers, was achieved by the condensation of hypophosphorous acid salts of (R)(+) or… Expand
The influence of α-aminophosphonic acids on the activity of aminopeptidase from barley seeds—an approach to determine the enzyme specificity
Inhibitory potencies of 24 α-aminophosphonic acids against barley seeds (Hordeum vulgare L.) metallo-aminopeptidase have been determined to evaluate structural requirements of this enzyme. The enzyme… Expand
Structure-Guided, Single-Point Modifications in the Phosphinic Dipeptide Structure Yield Highly Potent and Selective Inhibitors of Neutral Aminopeptidases
Seven crystal structures of alanyl aminopeptidase from Neisseria meningitides (the etiological agent of meningitis, NmAPN) complexed with organophosphorus compounds were resolved to determine the… Expand
Pentapeptides containing two dehydrophenylalanine residues ‐ synthesis, structural studies and evaluation of their activity towards cathepsin C
Synthesis, structural and biological studies of pentapeptides containing two ΔPhe residues (Z and E isomers) in position 2 and 4 in peptide chain were performed. All the investigated peptides adopted… Expand
Peptide p-nitrophenylanilides containing (E)-dehydrophenylalanine—synthesis, structural studies and evaluation of their activity towards cathepsin C
Tetrapeptide p-nitroanilides containing (E)-dehydrophenylalanine were synthesized and evaluated as inhibitors and substrates of cathepsin C. Peptides containing a free, unblocked amino group appeared… Expand
