Lomozik, Lechoslaw published the artcileCopper(II) ions as a factor interfering in the interaction between bioligands in systems with adenosine and polyamines, Related Products of catalysis-chemistry, the publication is Journal of Inorganic Biochemistry (1996), 63(3), 191-206, database is CAplus.

Noncovalent interactions were found to occur in metal-free adenosine-polyamine systems. Overall stability constants and equilibrium constants of adduct formation were determined The ranges in which the adducts occur overlap with the ranges in which nucleoside is deprotonated while polyamine is protonated. Stability constants and complex distribution in the Cu/Ado/PA (PA = polyamine) systems were identified. The coordination mode of the complexes in solution was determined Unlike in 1,3-diaminopropane (tn), putrescine (Put) and 1,7-diamino-4-azaheptane (3,3-tri), in the systems containing spermidine (Spd), the coordination dichotomy between the N(1) and N(7) atoms of the nucleoside disappeared. In some complexes occurring in the systems with tn, 3,3-tri (but not with Put and Spd), coordination with nitrogen atoms at axial positions was detected in solution Generally, however, a tendency to form square-planar structures dominates. Differences in the coordination mode of complexes in solution and solid complexes were determined

Bregier-Jarzebowska, R. published the artcileInteractions of diamines with adenosine-5′-triphosphate (ATP) in the systems including copper(II) ions, Recommanded Product: Propane-1,3-diamine dihydrochloride, the publication is Journal of Inorganic Biochemistry (2016), 73-82, database is CAplus and MEDLINE.

Interactions were studied in the systems ATP/tn and ATP/Put (tn = 1,3-diaminopropane, Put = putrescine) whereas the complexation reactions in ternary systems Cu(II)/ATP/tn and Cu(II)/ATP/Put. Results of the potentiometric and spectroscopic studies evidenced the formation of adducts of the type (ATP)H_x(PA), where PA = diamine. The thermodn. stability of the complexes and the mode of interactions were determined The interaction products are (ATP)H₃(tn) (1), (ATP)H₂(tn) (2), (ATP)H₃(Put) (3), and (ATP)H₂(Put) (4). On the basis of anal. of changes in the positions of NMR signals, in the pH range of (ATP)H₃(Put) (3) formation, the preferred centers of the interaction between ATP and Put are the endocyclic nitrogen atoms from the nucleotide. However, the shorter diamine tn in the entire pH range reacts with the phosphate groups from ATP. The pos. centers of noncovalent interactions are the protonated -NH⁺_x groups from amines. In both complexes Cu(ATP)H₂(tn) (9) and Cu(ATP)H₃(Put) (11) formed in ternary systems at pH < 6.5, the amines are in the outer sphere of coordination with the noncovalent interaction with anchoring Cu(ATP). Only the phosphate groups from the nucleotide take part in metalation. At higher pH in the range of Cu(ATP)(PA) complex formation, significant differences in the reactions of the two amines appear. The shorter one (tn) binds Cu(II) ions with two nitrogen atoms, while putrescine coordinates in the monofunctional mode, which is undoubtedly related to the differences in lengths of methylene chain. This explains the considerable differences in the stability of Cu(ATP)(tn) (10) and Cu(ATP)(Put) (12). In both complexes the nucleotide is coordinated through phosphate groups. As a result of noncovalent interactions ATP forms mol. complexes with 1,3-diaminopropane and 1,4-diaminobutane (putrescine). Significant differences in the mode of interactions between the two diamines were observed in ATP/diamine binary systems and in ternary systems Cu(II)/ATP/diamine, at high pH.

A series of polyguanidinium salts [(H₂N)₂C⁺NH]_nQ nX^– [I, Q = a polyvalent group, e.g., CH₂CH₂, (CH₂)₃, 1,2-cyclohexylene, nitrilotriethylene; n = valence of Q; X = Br, Cl, picrate, etc.] were prepared by several methods, the best of which was via polynitroguanidine intermediates. Acidity constants for some I were determined and the ability of I to complex phosphate and carboxylate anions was determined by titration data. Stability constants were determined for the complexes and, with NMR data, indicated a chelate effect for the polydentate ligands.

Boulanouar, Omar published the artcileDissociative electron attachment to DNA-diamine thin films: Impact of the DNA close environment on the OH^– and O^– decay channels, HPLC of Formula: 10517-44-9, the publication is Journal of Chemical Physics (2013), 139(5), 055101/1-055101/9, database is CAplus and MEDLINE.

We measure the desorption of anions stimulated by the impact of 0-20 eV electrons on highly uniform thin films of plasmid DNA-diaminopropane. The results are accurately correlated with film thickness and composition by AFM and XPS measurements, resp. Resonant structures in the H^–, O^–, and OH^– yield functions are attributed to the decay of transient anions into the dissociative electron attachment (DEA) channel. The diamine induces ammonium-phosphate bridges along the DNA backbone, which suppresses the DEA O^– channel and in counter-part increases considerably the desorption of OH^–. The close environment of the phosphate groups may therefore play an important role in modulating the rate and type of DNA damages induced by low energy electrons.

From d. measurements (25¡ã) of aqueous solutions at various concentrations of solute, apparent molar volumes of some open-chain bifunctional primary, secondary and tertiary amines were determined; the compounds studied were X(CH2)nNH2 (X = HO, MeO, H2N; n = 2,3) and 2-XCH2CH2OH (X = MeNH, EtNH, Me2N, Et2N) and their mono- and dihydrochlorides, for which ¦¤V1¡ã and ¦¤V2¡ã for the 1st and 2nd steps of proton ionization were calculated from the limiting partial molar volumes Values ¦¤V1¡ã for the above bifunctional amines are compared with the corresponding values for monofunctional amines, and the difference in ¦¤V1¡ã caused by the introduction of the 2nd hydrophilic center is discussed. The volumes and entropies of ionization of the amines and carboxylic acids are compared, and the deviations of these functions from predictions based on simple electrostatic theories are considered.

[Co(edampda)]ClO₄ [H₂edampda = N,N‘-bis(2-pyridylmethyl)ethylenediamine-N,N‘-diacetic acid], [Co(tpa)(H₂O)Cl](ClO₄)₂ [tpa = tris(2-pyridylmethyl)amine], [Co(uns-penp)(H₂O)Cl](ClO₄)₂ [uns-penp = N,N-bis(2-pyridylmethyl)ethylenediamine], and [Cu(uns-Hpenp)Cl₂]ClO₄ were prepared and characterized. In addition, the previously reported [Co(tpen)](ClO₄)₃ [tpen = N,N,N‘,N‘-tetrakis(2-pyridylmethyl)ethylenediamine], [Co(tptn)](ClO₄)₃ [tptn = N,N,N‘,N‘-tetrakis(2-pyridylmethyl)-1,3-propanediamine], and ¦¤¦«¦¤-(-)₅₈₉-[Co(tppn)](ClO₄)₃ [tppn = N,N,N‘,N‘-tetrakis(2-pyridylmethyl)-1,2-propanediamine] were prepared and characterized by high-resolution ¹H NMR spectroscopy for the 1st time. Two-dimensional ¹H NMR spectroscopy was utilized to complete the pyridine H assignments in the 1-dimensional ¹H NMR spectra of the tpen and tptn complexes. The 300-MHz ¹H NMR spectra of all of these complexes show good resolution for all of the hydrogens. The AB patterns of the pyridyl hydrogens and ethylenediamine hydrogens are discussed and correlated to 1 another. The AB coupling constants of the pyridyl rings are ?16 and 20 Hz for the G (in the plane of the ethylenediamine ring) and R (out of the plane of the ethylenediamine ring) chelate rings, resp.; these results are consistent with the well-documented AB coupling constants of (amino polycarboxylato)cobalt complexes. All of the ¹H NMR spectra were interpreted completely, and the usefulness of using AB coupling constants to assign individual AB patterns to R, G, or E chelate rings in polypyridyl complexes is demonstrated. In addition, the partial resolution of [Co(tpen)](ClO₄)₃ is reported, and the visible spectra of all of the complexes are reported.
