Design and Synthesisof Gramicidin S Analogs with High Antibiotic Activity

N-(2,4-Dinitrophenyl)tetrapeptide p-nitroanilides (Dnp-tetra-peptide-pNA) exhibit characteristic CD spectra when they take on β-turn conformation. Exciton coupling of electric transition dipoles of the two chromophores is thought to be the origin of […]
