Interactions of N-acetyl-l-cysteine with metals (Ni2+, Cu2+ and Zn2+): an experimental and theoretical study

Amino acid-type interactions of L-3,4-dihydroxyphenylalanine with transition metal ions: An experimental and theoretical investigation

“…In our previous works [15,20,21] we have noted that metal-coordination can inflict significant changes in the a-carbon geometry and the backbone structural features of the genetically encoded amino acids as well as their derivatives. Table S8 lists some of the structurally significant bond length values for the two L-dopa conformers and their metal complexes calculated using B3LYP/6e311þþG(d,p) level in both vacuum and solvent phase.…”

“…Presented herein are the solid-phase synthesis and characterization of the bivalent nickel, copper and zinc complexes of L-dopa employing a solvent-free mechanochemical (hand-grinding) procedure [15,20,21]. Chemical synthesis in the absence of solvent is a pollution-free environmentally affable approach [22], and has often been effectively utilized to achieve the desired reaction products that are otherwise difficult to obtain by means of the conventional solvent-phase methods [21].…”

Synthesis, Characterization and DNA Cleavage of Copper(II) Complex with D,L-Dithiothreitol

“…DNA shearing is an important phenomenon owing to its applications in the field of biology IR spectrum of DTT and its complex as shown in Figure 1 indicates the disappearance of the thiol(-SH) stretching peak at 2545 cm [16,17].…”

A combined experimental and quantum mechanical investigation on some selected metal complexes of l-serine with first row transition metal cations

“…Solid state chemistry is an interdisciplinary melding of chemistry, physics, engineering, and materials science that focuses on designing, synthesis as well as characterization of structural and physicochemical properties of new chemical compounds. Solvent-free solid state syntheses have been successfully employed in synthesis and characterization of several biologically significant metal complexes which are, otherwise, difficult to achieve by following the traditional synthetic methods or in presence of solvents [24,25]. On the other hand, computational chemistry employing high-level computing has been regarded as the third most heavily explored field of modern scientific research, standing alongside the conventional methods of theory and experiment.…”
