5-Pentafluorobenzyl-3-o-tolylhydantoin (2) was synthesized for reducing this π-electron density, and NMR studies have shown that we have succeeded in changing the conformation of 2 into an extended system instead of the folded conformation for the non-fluorinated compound, 5-benzyl-3-o-tolylhydantoin (1). Molecular modeling has also confirmed the extended structure for 2. An approach has been found for possibly modulating the physiological activity of peptides containing aromatic amino acids.
osteoblast adhesion. These data could lead to the development of new agents to improve cellular osseointegration and bone regeneration. Molecular modeling studies on prototypic compounds and αvβ3 or α5β1integrin supported the notion that ligand carboxylate fixing to the metal ion-dependent adhesion site in the β-subunit can be sufficient for binding the receptors, while the aryl side chains play a role in
