The folding of a metallopeptide

We have applied solid-phase synthesis methods for the construction of tris(bipyridyl) peptidic ligands that coordinate Fe(ii) ions with high affinity and fold into stable mononuclear metallopeptides. The main factors influencing the folding pathway and chiral control of the peptidic ligands around the metal ions have been studied both by experimental techniques (CD, UV-vis and NMR) and molecular modeling tools. Amongst the numerous molecular variables that have been studied, this study clearly illustrates how the chirality of a given set of aminoacids (proline in this case) of the peptide dictates the chirality of the metal center of the resulting metallopeptide. Moreover, the relatively hydrophobic peptidic models used in this work show that the most stable structures present reduced solvent contacts and, in counterpart, stabilize the cis configuration of the proline residues.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Application In Synthesis of Diethyl [2,2′-bipyridine]-5,5′-dicarboxylate

Synthesis, characterization and anticancer activity of gold(III) complexes with (1R,2R)-(-)-1,2-diaminocyclohexane

Two gold(III) complexes, [(DACH)AuCl2]Cl (1) and [(DACH)2Au]Cl3 (2), derived from (1R,2R)-(-)-1,2-diaminocyclohexane and sodium tetrachloroaurate dihydrate, NaAuCl4¡¤2H2O, were synthesized and fully characterized using elemental analysis and different physical methods, such as FTIR, 1H NMR, 13C NMR, solid-state NMR and X-ray crystallography. The data confirm the coordination of the DACH ligand to the gold(III) metal centre through its nitrogen atoms. According to in vitro cytotoxic studies, complex 2 was more effective against the three human tumor cell lines evaluated (the ovarian cancer cell line A2780, its cisplatin-resistant clone A2780cis and the classical Hodgkin lymphoma cell line L-540). The fold-resistance of the A2780 and A2780cis cells to cisplatin was about twofold lower for both gold(III) complexes.

Influence of the backbone of N5-pentadentate ligands on the catalytic performance of Ni(II) complexes for electrochemical water oxidation in neutral aqueous solutions

Two N5-chelated nickel complexes displayed decent catalytic activity and good stability for electrochemical water oxidation in phosphate buffer solutions at pH 7, with observed rate constants of 3.06 and 4.62 s-1, which are higher than those reported so far for molecular nickel catalysts in neutral solutions. The results revealed that the rigid backbone of N5-chelating ligands has a positive influence on the activity of the nickel catalysts.

Layered iron(II) spin crossover complex constructed by NH?Br – hydrogen bonds with 2 K wide thermal hysteresis, [Fe IIH3LMe]Br¡¤CF3SO3 (H3LMe = tris[2-(((2-methylimidazol-4-yl)methylidene) amino)ethyl]amine)

A series of compounds [FeIIH3LMe] Br¡¤Y¡¤nMeOH (Y=PF6- (1), AsF6- (2), SbF6- (3), CF3SO3- (4); n = 0 or 1) were synthesized, where H3LMe is a hexadentate N6 tripodal ligand of the neutral form, tris[2-(((2-methylimidazol-4- yl)methylidene)amino)ethyl]amine, and their structures and magnetic properties were investigated. The compounds 1-3 with counter anions Y=PF6-, AsF6-, and SbF6- contain methanol as a crystal solvent, and show no SCO behaviors, while the corresponding Cl- compounds have no crystal solvent and show a variety of SCO behaviors. The compound [FeIIH3L Me]Br¡¤CF3SO3 (4) has no crystal solvent and has isomorphous structure to the Cl- compounds, and shows an abrupt spin transition between the HS (S = 2) and LS (S = 0) states with a hysteresis about 2 K and large frozen-in effect below 72 K. The T 1/2? and T1/2? values are 98 and 96 K, whose values are higher than those of corresponding Cl- compound about 15 K and the width of hysteresis is narrower than that of corresponding Cl – compound about 2 K. The crystal structures of 4 were determined at 296 and 93 K, where the crystal system and space group showed no change between these temperatures. The structures at both temperatures have a same 2D layered structure, which is composed of NH?Br- hydrogen bonds between the Br- ion and the imidazole NH groups of three neighboring cations [FeIIH3LMe]2+. This network structure is the same as that of corresponding Cl- compound. The 600 nm light irradiation at 5 K induced the LIESST effect.
