complexation

Salcaprozate sodium (SNAC), an oral absorption promoter, enhances passive transcellular permeation through small intestinal epithelia, making it a potent delivery agent for oral heparin and insulin by increasing lipophilicity via non-covalent macromolecule complexation.

DL-Arginine is deployed in the study of amino acid complexation dynamics and the formation of crystal structures.

1-(2-Pyridylazo)-2-naphthol (PAN) is a complexation index agent.

Gramicidin S 2HCl, is an antibiotic. At concentrations of 40-80 μg mL, GS can reduce planktonic cell numbers within 20-40 minutes. For established biofilms, it effectively kills cells at concentrations of 100-200 μg mL without regrowth. This anti-biofilm effect results from peptide transmembrane transport and complexation with intracellular nucleotides (including the alarmone ppGpp). GS demonstrates wide-ranging activity against biofilm-forming, drug-resistant infections caused by E. faecalis, proving its efficacy in endodontic treatment. The successful treatment of persistent infections in two volunteer cases further confirms GS's potent therapeutic performance. These studies indicate that GS can be applied in certifying compounds used in endodontics.

Phytochelatin 4 (PC 4) a glutathione derived peptide and heavy metal detoxifier chelator consisting of 4 units of glu - cys and generated by PC synthase, is tolerant to Cd (cadmium) and is sequestered in vesicles after complexation with heavy metals.

3-Azidopropylamine, a click chemistry reagent characterized by its azide group, facilitates the complexation and transfection of plasmid DNA by reacting with the starch sugar present in potato starch [1].

2',3'-O-Isopropylidene-6-mercaptopurine riboside is a compound with excellent metal complexation activity. It is utilized in the study of mechanisms involving metal complexation.
