Thin films based on photosensitive bis-crown-ether dye were prepared by Langmuir and “modified spreading” techniques. The maximal changes in the surface pressure – and surface potential-mol. area isotherms (the relative mol. area increase was about 16%), in the absorption (shifts of ¦Ë _max up to 9 nm) and fluorescence (shifts of ¦Ë _max up to 17 nm) spectra of these films in the presence of diaminoalkane dihydrochlorides in the aqueous subphase were found.

Association constants of organic cations and anions with different charge separations, rigidity, and shapes were determined and compared with association constants of inorganic cations with organic anions and of inorganic anions with inorganic cations. Bjerrum’s theory of ion-pair formation is applicable to spherical inorganic ions, but not to ions having anisotropic charge distributions and shapes. For the latter, charge matching is an important factor in the association and is most effective for rigid ions.

Four new complexes of Cu(II) of stoichiometry [Cu(ATP)(polyamine)] containing polyamines (PA) ethylenediamine, 1,3-diaminopropane, spermidine, or spermine and ATP were prepared from aqueous solution at pH 6. Synthesis, characterization, thermogravimetric, vibrational spectroscopy, and ESR analyses are described and show that these complexes have similar mol. structures. IR spectra and the thermal anal. are briefly discussed based on the peculiarities of the complexes. The IR spectra of the ligands and their copper complexes were used to assign the various groups and compare the shifts due to complexation. ESR parameters values for the complexes show that Cu(II) is complexed in a similar way in the four complexes. Similarity in the coordination mode of complexes in solid state has been determined and discussed. The data obtained suggest that the four complexes contain one water mol. of hydration and are complexed through two oxygen atoms from ATP and through two nitrogen atoms of each polyamine.

Matsuo, Kimiko published the artcileThe effects of polyamines on the melting of poly(inosinic acid) plus poly(cytidylic acid) complex in solution, Synthetic Route of 10517-44-9, the publication is Bulletin of the Chemical Society of Japan (1966), 39(2), 347-52, database is CAplus and MEDLINE.

The thermal transition profile (melting profile) of the double-helical complex of poly(inosinic acid) and poly(cytidylic acid), poly (I + C), into random coils in solution was examined by observation of the absorbance at 248 m¦Ì. Increased cation concentrations raised the transition temperature (Tm) and made the transition more rapidly reversible. CH₃NH₃⁺, Na⁺, NH₄⁺, and Mg⁺⁺ were increasingly effective in that order. Diamines of the type ⁺H₃N-(CH₂)_n-NH₃₊ also raised Tm, the most effective being that with n = 3. Spermidine was even more effective, and spermine the most effective compound tested. Actinomycin D had little effect on Tm. Poly-L-lysine formed a complex with poly (I + C) with a stoichiometric molar ratio of NH₂😛 = 0.5:1.

Higuchi, Shigesada published the artcileEffects of polyamines on the melting of poly(riboadenylic acid) plus poly(ribouridylic acid) complexes in a solution, SDS of cas: 10517-44-9, the publication is Bulletin of the Chemical Society of Japan (1966), 39(9), 1886-93, database is CAplus and MEDLINE.

The effects of polyamines on the melting of poly(riboadenylic acid) (I) and poly(ribouridylic acid) (II) were studied, where melting is defined as a transition in solution from the double (or triple) helical conformation into random coils. I was obtained com., and II was prepared from polynucleotide phosphorylase obtained from Azotobacter vinelandii; the organism was precipitated from cold EtOH, dissolved in water, deproteinized by CHCl₃, dialyzed against an aqueous solution of 0.01M ethylene diamine tetraacetate, a M NaCl solution, and distilled water, and was then lyophilized. Ultracentrifugal sedimentation measurements and uv absorption determinations indicated that a 1:1 complex is formed between I and II. The absorbance was measured at 259 m¦Ì for several mixtures at 18¡ã in several concentrations of NaCl and Na citrate, NaCl, glycylglycine, and ethylenediamine solutions Absorbance observations indicated that a 1:2 complex of I:II was present in 0.1M NaCl + 0.01M glycylglycine buffer. The melting of the polymer mixtures was followed as dependent on the Na⁺ concentration in the solvent. Also, the melting was followed at 259 m¦Ì and 280 m¦Ì for the 1:1 mixture in 0.01M NaCl + 0.001 M Na citrate buffer. A mechanism is suggested for the phenomenon observed The effects of ethylenediamine dihydrochloride, 1,3-diaminopropane-2HCl, 1,4-diaminobutane-2HCl, 1,6-diaminohexane-2HCl, 1,8-diaminooctane-2HCl, and spermine-4HCl on the melting process were studied. Actinomycin D has no effect.

A glycoluril-based mol. tweezer I (R = EtO₂C) was prepared; its binding to monoalkylammonium and alkyldiammonium salts was determined Both the hydrophobic cavity and the phosphate groups of I contribute to its binding of ammonium salts; bulkier mols. and mols. bearing neg. charged groups such as carboxylates in amino acids bind less tightly due to steric interference and Coulombic repulsion, resp. The narrow cavity of I and ionic interactions between the phosphate groups of I and ammonium guests favor the binding of aliphatic diamines.

Koculi, Eda published the artcileCounterion Charge Density Determines the Position and Plasticity of RNA Folding Transition States, Computed Properties of 10517-44-9, the publication is Journal of Molecular Biology (2006), 359(2), 446-454, database is CAplus and MEDLINE.

The self-assembly of RNA structure depends on the interactions of counterions with the RNA and with each other. Comparison of various polyamines showed that the tertiary structure of the Tetrahymena ribozyme is more stable when the counterions are small and highly charged. By monitoring the folding kinetics of the ribozyme as a function of polyamine concentration, we now find that the charge d. of the counterions determines the positions of the folding transition states. The transition state ensemble (TSE) between U and N moves away from the native state as the counterion valence and charge d. increase, as predicted by the Hammond postulate. The TSE is broader and less structured when the RNA is refolded in polyamines rather than Mg²⁺. That the charge d. of the counterions determines the plasticity of the TSE demonstrates the importance of interactions among condensed counterions for the self-assembly of RNA structures. We propose that the major barrier to RNA folding is dominated by entropy changes when counterion charge d. is low and enthalpy differences when it is high.

Fabre, C. published the artcileGem effects: basicity measurement.

Geminal disubstitution does not systematically involve a decrease in the distance between the ends of an aliphatic chain. Thus, the pK values of I (R = H, Me) are identical. On the other hand, basicity differences were observed for II (m = 1; R = H, Me); no basicity differences were observed for II (m = 2, 3; R = H, Me).
