“…Red Salmon testes DNA is isolated from the sperm cells of Oncerhynchus keta , which is a good source of non‐mammalian DNA. This DNA suffices for DNA interaction studies performed in vitro and is commonly used to observe DNA interactions, such as this, via UV/Vis spectroscopy 49–55. A hyperchromic effect was observed as the absorbance of complex 7 at 303 nm increased upon addition of DNA.…”

Trinuclear and model mononuclear cationic monodentate Rh III , Ir III and Ru II complexes with alkylated 1,3,5-triaza-7-phosphaadamantane (PTA) moieties have been prepared and characterized using NMR and IR spectroscopy, HR-ESI mass spectrometry and elemental analysis. The metals coordinate to the ligands via the phosphorus of the PTA, and this was confirmed by shifts in the 31 P{ 1 H} NMR spectra. The cytotoxicities

Cyclodextrins are able to act as host molecules in supramolecular chemistry with applications ranging from pharmaceutics to detergency. Among guest molecules surfactants play an important role with both fundamental and practical applications. The formation of cyclodextrin/surfactant host-guest compounds leads to an increase in the critical micelle concentration and in the solubility of surfactants. The possibility of changing the balance between several intermolecular forces, and thus allowing the study of, e.g., dehydration and steric hindrance effects upon association, makes surfactants ideal guest molecules for fundamental studies. Therefore, these systems allow for obtaining a deep insight into the host-guest association mechanism. In this paper, we review the influence on the thermodynamic properties of CD-surfactant association by highlighting the effect of different surfactant architectures (single tail, double-tailed, gemini and bolaform), with special emphasis on cationic surfactants. This is complemented with an assessment of the most common analytical techniques used to follow the association process. The applied methods for computation of the association stoichiometry and stability constants are also reviewed and discussed; this is an important point since there are significant discrepancies and scattered data for similar systems in the literature.In general, the surfactant-cyclodextrin association is treated without reference to the kinetics of the process. However, there are several examples where the kinetics of the process can be investigated, in particular those where volumes of the CD cavity and surfactant (either the tail or in special cases the head group) are similar in magnitude.This will also be critically reviewed.

“…Salmon testes DNA sodium salt (DNA) has been employed to study various disease‐related cellular and biochemical studies with a strong potential of its deployment in separation applications as well. DNA binding to zwitterionic model membranes was investigated to ascertain the roles of metal ions in the mechanism as to how DNA intercalates the lamellae . DNA‐cationic surfactant interaction was studied to explore the mechanism with an eye to its application in gene therapy .…”

Polysaccharides of marine origin, for example, agarose (Ag) and alginic acid (Alg)-based new nano-size monoamido amino acid derivatives are synthesized and their protein-like characteristics are evaluated. Two new agarosebased nanosize amino acid derivatives are obtained by partial amidation of agarose succinate half-ester (Ag-SA; DS 0.95) employing aliphatic acyclic and cyclic diamines, for example, 1,6-hexamethylenediamine (HDA) and trans-1,4-cyclohexanediamine (CHDA), named Ag-SA-hexamethylenemonoamido (AEAm) and Ag-SA-cyclohexanemonoamido (AECAm) amines (DSs 0.47, 0.35), recording isoelectric points (pIs) 7.9 and 6.4, respectively. Alginic acid, extracted from the Indian seaweed species, Sargassum tenerrimum, is functionalized with ethylene diamine (EDA) affording a nanosize alginic-acid-based monoamido amino acid (Alg-EDA; DS 0.47; pI 3.40). All of these three nanosize monoamido amino acids (DLS; (nm) AEAm 0.65, 80.9; AECAm 0.65, 7.54, and 107.4; Alg-EDA 0.89, 2.0, 50, and 61.0) exhibit protein-mimicking functions interacting with Salman testes DNA and bovine serum albumin (BSA), displaying different complexation and decomplexation profiles in a varying pH regime. These nanobody polysaccharide-based protein-like large molecules may be of potential utility in the domains of pH-responsive drug delivery, separations as well as chiral sensing applications.
