Anchoring of Aminophosphonates on Titanium Oxide for Biomolecular Coupling [PDF]

, 2019
Aminophosphonates were chosen for a first step functionalization of TiO2 grown on titanium, as they possess a phosphonate group on one end, that can be exploited for coupling with the oxide surface, and an amino group on the other end to enable further ...

Infrared spectra of aminophosphonic acids. II

Croatica Chemica Acta, 1972
Infrared spectra of diesters, monoesters and sodium salts of the monoesters of several new aminophosphonic acids containing benzeneazo group, e.g. derivatives of [a-(4-benzeneazoanilino)-N-benzyl] phosphonic acid, and [4-benzeneazo-a-(anilino)-benzyl]phosphonic acid, have been studied.

Mechanosynthesis of polymer α-aminophosphonates

Bulletin of the South Ural State University series "Chemistry"
Kabachnik–Fields reaction is widely used to obtain α-aminophosphonates, including polymeric ones. In addition, methods for the mechanosynthesis of α-aminophosphonates under mechanosyn-thesis conditions are being developed. The article examined methods for the preparation of aryl-substituted polymeric α-aminophosphonates by reacting isomeric ...

In vitro antitumour activity, safety testing and subcellular distribution of two poly[oxyethylene(aminophosphonate-co-H-phosphonate)]s in Ehrlich ascites carcinoma and BALB/c 3T3 cell culture systems

Biotechnology & Biotechnological Equipment, 2016
Two polyphosphoesters containing anthracene-derived aminophosphonate and hydrophilic H-phosphonate repeating units, poly[oxyethylene(aminophosphonate-co-H-phosphonate)]s (1 and 2), were tested for the in vitro antitumour activity on cell cultures derived

Microwave Synthesis and Antimicrobial Evaluation of Selected Aminophosphonates

Chemistry Proceedings
In the search for new bioactive molecules, a series of new molecules from the phosphonate family were synthesized via the Kabachnik–Fields reaction (phosphonate ester) and the Irani–Moedritzer reaction (phosphonic acids).

New aminophosphonates with antioxidative activity.

Cellular & molecular biology letters, 2002
The antioxidative activity of some newly synthesized aminomethanephosphonic acid derivatives was studied. The compounds studied differed in their polarity and the hydrophobicity of the electronic substituents at their nitrogen and phosphorus atoms.
