Non-covalent interactions in clathrate complexes
Journal of Coordination Chemistry, 2021Intermolecular interactions in clathrates are compared to those in supramolecular complexes in solution, with an emphasis on van der Waals, or dispersive contributions.

Studying non-covalent drug–DNA interactions
Archives of Biochemistry and Biophysics, 2015Drug-DNA interactions have been extensively studied in the recent past. Various techniques have been employed to decipher these interactions. DNA is a major target for a wide range of drugs that may specifically or non-specifically interact with DNA and affect its functions.

Genotoxicity of non-covalent interactions: DNA intercalators
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2007This review provides an update on the mutagenicity of intercalating chemicals, as carried out over the last 17 years. The most extensively studied DNA intercalating agents are acridine and its derivatives, that bind reversibly but non-covalently to DNA. These are frameshift mutagens, especially in bacteria and bacteriophage, but do not otherwise show a

Nanopore Stochastic Sensing Based on Non-covalent Interactions
Analytical Chemistry, 2021A variety of species could be detected by using nanopores engineered with various recognition sites based upon non-covalent interactions, including electrostatic, aromatic, and hydrophobic interactions. The existence of these engineered non-covalent bonding sites was supported by the single-channel recording technique. The advantage of the non-covalent

Non-covalent interactions in the monohydrated complexes of 1,2,3,4–tetrahydroisoquinoline
Journal of Molecular Modeling, 2023The eleven monohydrates of 1, 2, 3, 4-tetrahydroisoquinoline (THIQ) are analyzed through natural bond orbital (NBO) analysis and QTAIM methods employing M06-2X functional in DFT and MP2 methods. Here, the role of OH bonds as an acceptor and donor is critically analyzed.

Non-Covalent Interactions: Complexes of Guanidinium with DNA and RNA Nucleobases
The Journal of Physical Chemistry B, 2013Considering that guanidine-based derivatives are good DNA minor groove binders, we have theoretically studied, using the Polarizable Continuum model mimicking water solvation, the complexes formed by the biologically relevant guanidinium cation and the DNA and RNA nucleobases (adenine, guanine, cytosine, thymine, and uracil).

Non Covalent Interactions In Protein Complexes
2007While the electrostatic interactions between the complementary charged proteins increase their interaction, desolvation of the charged and polar amino acid residues destabilizes the protein - protein complex. We studied influence of the electrostatic interactions on formation of the protein complexes between Ras and Rap and their effectors Raf and ...

Non-covalent interactions – QTAIM and NBO analysis
Journal of Molecular Modeling, 2012MP2(full)/6-311++G(3df,3pd) calculations were carried out on complexes linked through various non-covalent Lewis acid - Lewis base interactions. These are: hydrogen bond, dihydrogen bond, hydride bond and halogen bond. The quantum theory of ´atoms in molecules´ (QTAIM) as well as the natural bond orbitals (NBO) method were applied to analyze properties

Non-covalent interactions between proteins and polysaccharides
Biotechnology Advances, 2006Foods with novel or improved properties can be created by utilizing non-covalent interactions between proteins and polysaccharides. In solution, either attractive or repulsive interactions between proteins and polysaccharides can be used to create microstructures that give foods novel textural and sensory properties.
