Unnatural Amino Acid: 4-Aminopyrazolonyl Amino Acid Comprising -Peptides Forms Organogel With Co-Solvent (EtOAc:Hexane).

Ampyrone is an amino-functionalized heterocyclic pyrazolone derivative that possesses therapeutic values such as analgesic, anti-inflammatory, and antipyretics. The chemical structure of ampyrone exhibits excellent hydrogen bonding sites and is considered as the potential scaffold of supramolecular self-assembly. Recently, this molecule has been derived into unnatural amino acids such as aminopyrazolone amino acid and its peptides.
