The sequestering ability of polyamines and aminoacids of biological and environmental relevance (namely, ethylenediamine, putrescine, spermine, a polyallylamine, a branched polyethyleneimine, aspartate, glycinate, lysinate) toward dimethyltin(IV) cation was evaluated. The stability of various dimethyltin(IV) / ligand species was determined in NaCl(aq) at t = 25 degrees C and at different ionic ...

In the present study, the influence of chromium(III) complexes (acetate, chloride, glycinate, histidinate, lactate and propionate) on insulin binding and signal transduction [phosphorylation of tyrosine and serine in the insulin receptor substrate (IRS)-1] was investigated in vitro using three experimental models: isolated rat liver membranes and cultured mouse C2C12 myoblasts or 3T3-L1 preadip...

The addition of N-(diphenylmethylene)glycinate esters (Ph2C=NCH2CO2R) 3-6 to [60]fullerene under Bingel conditions gives, respectively, the methano[60]fullerenyl iminoesters 7-10. Upon treatment of 7-9 with sodium cyanoborohydride, in the presence of a protic or a Lewis acid, a novel reductive ring-opening reaction occurred to give the corresponding 1,2-dihydro[60]fullerenyl glycine derivatives...

In the title compound, [Cu(2)(C(2)H(4)NO(2))(2)(C(10)H(6)O(6)S(2))(H(2)O)(6)], the naphthalene-disulfonate group lies on a center of inversion and bridges two glycinate-chelated Cu(II) atoms. The Cu(II) atom exists in a CuNO(4) square-pyramidal geometry that is distorted towards an octa-hedron owing to a long Cu-O(sulfonate) bond [2.636 (2) Å]. In the crystal, extensive N-H⋯O and O-H⋯O hydrogen...

Cu]-N-(2-hydroxyacetophenone)glycinate ([Cu]NHAG) was prepared using in house-made NHAG ligand and [Cu]CuCl2 produced via the Zn(p,x)Cu (180μA proton irradiation, 22MeV, 3.2h) and purified by a ion chromatography method. [Cu]NHAG radiochemical purity was >98% and >99.9% by RTLC and HPLC methods respectively after purification by SPE. [Cu]NHAG was administered into normal and tumor bearing mice ...

The biological properties of Trichoderma Viride fungi allow them to be effectively used in the technologies crop waste disposal, production organic, environmentally friendly fertilisers, and prevention soil diseases plants. growth development these depend on a number trace elements that are found medium. Copper is great importance among elements. establishment ability use copper as stimulator b...
