A bioinspired approach toward efficient supramolecular catalysts for CO2 conversion
Elsevier (2022-12-21)Nature uses enzymes for affording astonishingly efficient chemical transformations with high chemo-, regio-, and stereoselectivity (e.g., carbonic anhydrase for CO2 conversion). Such sophisticated biomolecules lead to ... -
Bisferrocenyl-functionalized pseudopeptides: access to separated ionic and electronic contributions for electrochemical anion sensing
The Royal Society of Chemistry (2016-03)Pseudopeptidic receptors containing ferrocene fragments have been prepared and their response to a series of anions was measured by a voltammetry of microparticles methodology. Such water-insoluble compounds yield ... -
Doubly chiral pseudopeptidic macrobicyclic molecular cages: Water-assisted dynamic covalent self-assembly and chiral self-sorting
Elsevier (2022-06-27)Taking advantage of the dynamic covalent chemistry approach, four different cages were synthesized by condensation of tripodal pseudopeptides with 4,4′-biphenyldicarboxyaldehyde. Whereas undesired products of polymeric ... -
Macrocycle synthesis by chloride-templated amide bond formation
American Chemical Society (2016)A new family of pseudopeptidic macrocyclic compounds has been prepared involving an anion-templated amide bond formation reaction at the macrocyclization step. Chloride anion was found to be the most efficient template ... -
Open chain pseudopeptides as hydrogelators with reversible and dynamic responsiveness to pH, temperature and sonication as vehicles for controlled drug delivery
Elsevier (2022-01-25)A new family of open chain-pseudopeptidic compounds displaying a pendant carboxylic group have been prepared with excellent yields. Their self-assembly has been studied under different conditions and in different media. ... -
Pseudopeptidic fluorescent on-off pH sensor based on pyrene excimer emission: Imaging of acidic cellular organelles
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 ... -
Recognition of Free Tryptophan in Water by Synthetic Pseudopeptides: Fluorescence and Thermodynamic Studies
WILEY-VCH Verlag GmbH & Co. KGaA (2014-06)Pseudopeptidic receptors containing an acridine unit have been prepared and their fluorescence response to a series of amino acids was measured in water. Free amino acids, not protected either at the C or the N terminus, ... -
Tight and Selective Caging of Chloride Ions by a Pseudopeptidic Host
WILEY-VCH Verlag GmbH & Co. KGaA (2014-06)The selective molecular recognition of chloride versus similar anions is a continuous challenge in supramolecular chemistry. We have designed and prepared a simple pseudopeptidic cage (1 a) that defines a cavity suitable ... -
Unravelling the Supramolecular Driving Forces in the Formation of CO2-Responsive Pseudopeptidic Low-Molecular-Weight Hydrogelators
MDPI (2022): A new family of C2 -symmetric pseudopeptides with a high functional density for supramolecular interactions has been synthetized through the attachment of four amino acid subunits to a diamino aliphatic spacer. The ...
