Molecular Recognition of Arginine by Supramolecular Complexation with Calixarene Crown Ether Based on Surface Plasmon Resonance
Arginine plays an important role in cell division and the functioning of the immune system. We describe a novel method by which arginine can be identified using an artificial monolayer based on surface plasmon resonance (SPR). The affinity of arginine binding its recognition molecular was compared to that of lysine. In fabrication of an arginine sensing interface, a calix[4]crown ether monolaye...
متن کاملInvestigating Molecular Recognition by Mass Spectrometry: Characterization of Calixarene-Based Self-Assembling Capsule Hosts with Charged Guests
Capsules derived from the reversible assembly of calixarene tetraureas have been characterized by electrospray ionization mass spectrometry. Ion labeling was achieved through the encapsulation of ammonium ions as guest molecules. The gas-phase ion structure of the parent calixarene was determined by isotope pattern analysis, inclusion of labeled guests, and collision experiments. Competition ex...
متن کاملIncorporation of a calixarene-based glucose functionalised bolaamphiphile into lipid bilayers for multivalent lectin recognition.
The synthesis, characterization and inclusion in liposomes of a glucosylated bolaamphiphile built on a calix[4]arene scaffold are described. The new glucocalixarene bolaamphiphile destabilizes bilayers of saturated lipids whereas it rigidifies those of unsaturated lipids, thus reducing leakage of calcein from the liposome internal aqueous compartment. Moreover, from fluorescence and turbidimetr...
متن کاملStructural basis for molecular recognition at serotonin receptors.
Serotonin or 5-hydroxytryptamine (5-HT) regulates a wide spectrum of human physiology through the 5-HT receptor family. We report the crystal structures of the human 5-HT1B G protein-coupled receptor bound to the agonist antimigraine medications ergotamine and dihydroergotamine. The structures reveal similar binding modes for these ligands, which occupy the orthosteric pocket and an extended bi...
متن کاملExtended Calix[4]arene-Based Receptors for Molecular Recognition and Sensing
Recent advances in the area of recognition and sensing have shown that artificial receptors derived from extended calix[4]arenes bearing multiple π-conjugated fluorophoric or chromophoric systems have found useful to enhance binding affinity, selectivity and sensitivity for recognition and sensing of a targeted ion or molecule. A comprehensive review of various π-conjugation-extended calyx[4]ar...
