BIOLOGICAL ACTIVITY OF AMINOPHOSPHONIC ACIDS

Phosphorus, Sulfur, and Silicon and the Related Elements, 1991
Abstract Aminophosphonates are analogues of amino acids in which a carboxylic moiety is replaced by phosphonic acid or related groups. Acting as antagonists of amino acids, they inhibit enzymes involved in amino acid metabolism and thus affect the physiological activity of the cell. These effects may be exerted as antibacterial, plant growth regulatory

Aminophosphonic Acids and Derivatives. Synthesis and Biological Applications

Current Medicinal Chemistry, 2010
In recent years, phosphonic acids and their derivatives have received increasing attention as analogues of a series of naturally occurring phosphates and as "bio-isosteric phosphorus analogues" of amino acids. Unlike a phosphate group, the phosphonate moiety is not readily hydrolyzed, in a biological environment, by the enzymes involved in the ...

Complexes of aminophosphonates 5. Interaction of copper(II) ion with aminophosphonic inhibitors of leucine aminopeptidase

Journal of Inorganic Biochemistry, 1990
Abstract Potentiometric and spectroscopic studies on the coordination of Cu(II) ion with aminophosphonic inhibitors of leucine aminopeptidase have shown that 1-amino-2-alkoxyalkylphosphonic acids and 1-amino-2-(N-alkylamino)alkylphosphonic acids are very effective chelating agents.

New synthesis of fluorinated 2-aminophosphonates

Journal of Fluorine Chemistry, 1995
Abstract The reaction of perfluoroalkylated α,β-unsaturated phosphorates with saturated methanolic ammonia solution afforded 2-amino-2-perfluoroalkylethylphosphonates, and with benzylamine gave 2-benzylamino-2-perfluoroalkylethylphosphonates which upon hydrogenation gave 2-amino-2-perfluoroalkylethylphosphonates.

Hydrogen Bonding in α-Aminophosphonic Acids

Phosphorus, Sulfur, and Silicon and the Related Elements, 2012
Abstract The molecular and crystal structures of two α-aminophosphonic acids with small substituents at the α-carbon atom—(1-aminoethyl)phosphonic acid 1 and (1-amino-2,2-dimethylpropyl)phosphonic acid monohydrate 4—were determined by single-crystal X-ray diffraction studies.

Aminophosphonates: Synthesis and practical application

2012
There is an increasing interest in amine derivatives of phosphonic acids. The α- aminophosphonates, organophosphorus analogs of natural amino acids are most studied and attracted for the specialists in various branches of chemistry - biochemists, pharmacologists and synthetic chemists.
