Usage

General Description

3,3',3'',3'''-(ethylenedinitrilo)tetrapropionic acid, also known as EDTA, is a chelating agent that is frequently used in a variety of industrial and consumer applications. It is a polydentate ligand that forms stable complexes with metal ions, making it useful in the treatment of water and wastewater, as well as in the formulation of cleaning and personal care products. Its ability to sequester metal ions also makes it effective in controlling undesirable metal-catalyzed processes, such as the oxidation of oils and the degradation of dyes. EDTA is also used in the food industry as a preservative, as well as in the medical field as a chelating agent for the treatment of heavy metal poisoning and as a calcium chelator for the prevention of blood clotting. Despite its widespread use, there is ongoing concern about the environmental impact of EDTA and efforts are being made to develop more sustainable alternatives.

Synthesis of non-cytotoxic poly(ester-amine) dendrimers as potential solubility enhancers for drugs: Methotrexate as a case study

This study describes the synthesis of two new families of dendrimers based on the esterification of N-alkylated 3-amine-1-propanol with two different cores, adipic acid (1st and 2nd generations) and ethylenediamine (generation 1.5), both with carboxylic acid end groups, offering a wide variety of further modifications at the periphery. According to the cytotoxic evaluation of the dendrimers and their possible degradation products within cell lines, these materials could be considered as innocuous. In preliminary studies, the synthesized dendrimers proved to be potential enhancers of solubility of highly hydrophobic drugs, like methotrexate, widely used in chemotherapy.
