Cation binding characteristics of tetrandrine studied by UV-Vis absorption and fluorescence spectroscopies

Removal of procainamide and lidocaine on Amberlite XAD7HP resin and of As(V), Pb(II) and Cd(II) on the impregnated resin for water treatment

“…The two anesthetic drugs have amide and amine groups that may interact with metal ions frequently found in water such as Cd(II), As(V) and Pb(II) involving the non-participating electrons pair of nitrogen and the carbonyl bond [20,[45][46][47][48][49][50][51][52].…”

Host-Guest Chemistry of Alkaloids

“…Unsubstitute tatrandrine binds alkaline earth cations in MeCN and THF with logK values in the range 3.5-5.5 depending on the solvent and counter-ion [53]. No interaction with alkali cations was detected.…”

Spectroscopic and nano-molecular modeling investigation on the binary and ternary bindings of colchicine and lomefloxacin to Human serum albumin with the viewpoint of multi-drug therapy

“…Its amino acid sequence contains a total of 17 disulfide bridges, one free thiol (Cys-34) and a single tryptophan (Trp-214). It is capable of binding a wide variety of drugs and xenobiotics [6][7][8][9][10][11]. Binding of drugs to plasma proteins is an important pharmacological parameter, since it frequently affects the distribution and elimination of a drug as well as the duration and intensity of its physiological action [12][13][14].…”
