Molecular Conformation of Inosine

Nature, 1969
INOSINE is one of the rare nucleosides found in nucleic acids. It occurs especially in transfer ribonucleic acid where it appears to form part of a number of anticodons1,2. It can form a base pair with any one of the bases adenine, uracil or cytidine in the third codon1,2 position, and the possibility of atypical base pairs is part of the “wobble ...

Molecular Conformation of GABA

Nature New Biology, 1971
CURTIS et al.1,2 have described evidence suggesting that the alkaloid bicuculline is a specific antagonist to the action of γ-aminobutyric acid (GABA), a possible inhibitory transmitter in the mammalian brain3,4. By considering structural models, they suggested3 as a stereochemical basis for this antagonism a geometrical configuration in which the N ...

Molecular Conformation of Deoxyuridine

Nature, 1971
THE structure determination of deoxyuridine was undertaken as part of a series of conformational studies of nucleic acid components. Such studies give information about the preferred conformation of nucleosides and nucleotides1,2, and may clarify the conformational differences and changes that occur in nucleic acids.

Molecular Conformation and Crystallization: The Case of Ethenzamide

Crystal Growth & Design, 2012
Ethenzamide is a small, conformationally labile pharmaceutical molecule which crystallizes in an unusual conformation relative to both its co-crystals and to similar molecules found in the Cambridge Structural Database. Relative to its co-crystals, large ethenzamide crystals are challenging to grow, a property which may be linked to the crystal ...

Molecular Conformations of 5-Iodouridine

Nature, 1970
THE structure of unusual nucleic acid components is of importance in relation to conformational and model building studies on nucleic acids in general and those concerning tRNA in particular. In the case of 5-iodouridine (Fig. 1) it is particularly desirable to know the crystal structure in order to compare the effects of ionizing radiation on single ...

Molecular conformation of prostaglandin A1

Prostaglandins, 1973
Abstract The crystal and molecular structure of prostaglandin A1 (PGA1) has been determined by X-ray diffraction. (Space group P212121, a = 18.10 A A , b = 21.09 A A , c = 5.42, Z = 4) . Comparison of the structure of PGA1 with that of PGF1β (determined previously as the tribromobenzoate) indicates significant ...

Molecular Structure and Conformation of Dinitrosylheme

Journal of the American Chemical Society, 2003
DFT calculations indicate a surprisingly strong cis orientational preference of the two NO ligands of dinitrosylheme, a unique reactive species of potential biological relevance that has been recently generated and spectroscopically characterized at low temperature.
