Chiral Imidazolium Receptors for Citrate and Malate: The Importance of the Preorganization
Faggi, Enrico; Porcar Garcia, Raul; Bolte, Michael; Luis, Santiago V.; Garcia-Verdugo, Eduardo; Alfonso Rodríguez, Ignacio American Chemical Society (2014-09)A family of simple receptors formed by two or three cationic imidazolium arms attached to a central aromatic linkage and displaying different conformational flexibility has been synthesized from the enantiopure ... -
Minimalistic amino amides as models to study N–Hπ interactions and their implication in the side chain folding of pseudopeptidic molecules
Faggi, Enrico; Luis, Santiago V.; Alfonso Rodríguez, Ignacio Royal Society of Chemistry (2013)The structural study of simple amino amides derived from natural amino acids showed a unique conformational pattern for the aromatic residues, being clearly different from that for the aliphatic derivatives. The results ... -
Pseudopeptidic Cages as Receptors for N-Protected Dipeptides
Faggi, Enrico; Moure, Alejandra; Bolte, Michael; Vicent Barrera, Cristian; Luis, Santiago V.; Alfonso Rodríguez, Ignacio American Chemical Society (2014-04)The molecular recognition of short peptides is a challenge in supramolecular chemistry, and the use of peptide-like cage receptors represents a promising approach. Here we report the synthesis and characterization of a ... -
Pseudopeptidic fluorescent on-off pH sensor based on pyrene excimer emission: Imaging of acidic cellular organelles
Faggi, Enrico; Serra-Vinardell, Jenny; Pandey, Mrituanjay D.; Casas, Josefina; Fabriàs, Gemma; Luis, Santiago V.; Alfonso Rodríguez, Ignacio Elsevier (2016)A pseudopeptidic compound comprising a central C2 symmetric bis(aminoamide) moiety derived from the amino acid serine and two pyrene groups at the ends, Et(SerPyr)2, has been efficiently prepared. In aqueous solution, it ... -
Stereoselective recognition of the Ac-Glu-Tyr-OH dipeptide by pseudopeptidic cages
Faggi, Enrico; Vicent Barrera, Cristian; Luis, Santiago V.; Alfonso Rodríguez, Ignacio Royal Society of Chemistry (2015)Pseudopeptidic molecular cages are appealing receptors since they can display different polar and nonpolar interaction sites in a modular framework and a controlled disposition. Inspired by previous host– guest knowledge, ... -
Supramolecular protection from the enzymatic tyrosine phosphorylation in a polypeptide
Faggi, Enrico; Pérez, Yolanda; Luis, Santiago V.; Alfonso Rodríguez, Ignacio Royal Society of Chemistry (2016-05)Here we report two new artificial pseudopeptidic cages that bind the EYE peptide epitope in pure water at physiological pH (as studied by fluorescence and NMR spectroscopies). The supramolecular complexation of the Tyr ...
