Imidazole derivatives differentially destabilize the low pH conformation of lysozyme through weak electrostatic interactions

The structure-stability-function paradigm of proteins is highly governed by the pre-existence of repulsive and attractive non-covalent interactions. Electrostatic interactions with charged solvent molecules at the protein surface can contribute significantly to their stability. In order to unravel the electrostatic contributions of the positively charged species on a protein, we have studied the interactions of the imidazole derivatives (imidazole, histidine and histamine) with Hen Egg Lysozyme (HEL) in the pH range 4-2. At acidic pH, these compounds are reported to form charge transfer complexes (CTCs) with HEL through their protonated imidazole moiety with indole ring of protein’s tryptophan. Although literature is available on the molecular geometry and functional roles of CTCs, no knowledge is available on the electrostatic interactions and stability attenuation features of these complexes. To unravel the stability aspects of HEL upon binding to imidazole derivatives, we have performed pH dependent stability and structural studies using various biophysical techniques. Our results evidenced a stability attenuation of HEL in the pH range 4-2, both in its apo conformations and also in complex with imidazole derivatives. Moreover, at pH values 4 and 3 all these positive charged compounds destabilized HEL by a Tm of 57 degrees C, leaving the pH 2 conformation untouched. Structural analysis suggested that interactive networks of negatively charged Glu/Asp residues of the protein with CTC forming compounds is responsible for such differential stability attenuation. We believe that our results are handy to the researchers in deciphering the contributions of weak non-covalent interactions in biomolecular recognition processes.

Iodine-Catalyzed C-H Functionalization of Cyclopentenedione with Benzamidine: A Double Dehydrogenative Oxidative Cyclization to Access Fused Imidazoles

A double C-H functionalization of cyclopentenedione with benzamidine hydrochloride catalyzed by iodine has been disclosed for synthesizing fused imidazole derivatives. This methodology leads to a variety of fused imidazole derivatives and requires a sub-stoichiometric amount of iodine as a catalyst and aqueous tert-butyl hydroperoxide (TBHP) as an oxidant. This reaction involves a double-cross dehydrogenative coupling (CDC) of 1,3-cyclopentenedione and benzamidine hydrochloride to form two C-N bonds in a consecutive manner within short reaction time. A plausible mechanism has been proposed based on the mass spectrometric analysis.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 144689-94-1. Recommanded Product: 144689-94-1.

Synthesis, crystal structure and luminescent properties of transition metals complexes based on imidazole derivatives

In this paper, we synthesized complexes of imidazole derivatives. The structures of complexes Ni(L1)(2)(CNS)(2) (complex 1), Zn(L2)(2)(CNS)(2) (complex 2) and MnL3Cl2 (complex 3) were determined by X-ray diffraction in those complexes. The space groups of complex 1,2 and 3 are C2c/c, P-1 and P21/n, respectively. Ni (II), Zn (II) ions are coordinated by four nitrogen atoms of ligands and two nitrogen atoms of thiocyanate. Mn(II) ion is coordinated by three nitrogen atoms of ligand and two chlorine atoms. Single crystal X-ray studies on complex 2 and complex 3 indicate that the molecules of the complexes 2 and 3 link together through intermolecular N-H center dot center dot center dot S hydrogen bonds and N-H center dot center dot center dot Cl hydrogen bonds, respectively. The DFT (Density Functional Theory) and luminescent properties of these complexes are discussed. The calculated results are in good agreement with the experimental data.
