Preparation and characterization of a water-soluble peptide cyclophane as a cationic host for various hydrophobic guest molecules
摘要:
A novel water-soluble peptide cyclophane was prepared by condensation of N,N'N'',N'''-tetrakis(5-carboxynicotinoyl)-2,11,20,29-tetraaza[3.3.3.3]paracyclophane with L-valine methyl ester, followed by quaternization with methyl iodide, and its guest-binding behavior was examined by means of electronic absorption spectroscopy and electrospray ionization (ESI) mass spectrometry.
