Solution stability constants of some metal complexes of derivatives of catechol

Polyacrylamide-Based Sorbents for the Removal of Hazardous Metals

“…Under the actual experimental conditions, the exchange capacity is in the following order: Pb(II) > Cu(II) > Cd(II). This finding is in line with the order of binding constants of metallic ions with catechol derivatives (Athavale et al 1966). This order in metallic uptake Pb(II) > Cd(II) was also observed when bentonite and clinoptilolite were used as clay adsorbent (Faghihian and Nejati-Yazdinejad 2009).…”

A computational study of CH4 storage in porous framework materials with metalated linkers: connecting the atomistic character of CH4 binding sites to usable capacity

“…MOFs containing catechol ligands were recently synthesized and metalated by Fe 3+ , Cr 3+ and Pd 2+ . 61 – 63 The specific metalations discussed here have yet to be attained, however, there is experimental evidence 64 for the preparation of catecholate complexes with Mg 2+ , and other studies, focused on the role of melamine in biological Ca 2+ regulation, indicate that both Ca 2+ and Mg 2+ form complexes with catechol even in aqueous solutions. 65 – 69 …”

Flavonoids: True or promiscuous inhibitors of enzyme? The case of deoxyxylulose phosphate reductoisomerase

“…Flavonoids containing a catechol group were accordingly selected to optimize the number of chelation sites. Indeed, catechols form stable complexes with the magnesium dication Mg 2+ , a hard metal ion [20]. In addition, flavonoids may act as potential efficient inhibitors as the DXR has hydrophobic pockets situated close to the active site where they might interact and interfere with the enzymatic activity [21].…”
