Conformation of acetylaminofluorene and aminofluorene modified guanosine and guanosine derivatives

Biochemical and Biophysical Research Communications, 1980
Abstract Acetylaminofluorene and aminofluorene modified Guo, GMP, d(GpA) and d(ApG) have been studied by circular dichroism and 1H nuclear magnetic resonance. Aminofluorene modified Guo is preferentially in the anti conformation and acetylaminofluorene modified Guo in the syn conformation.

QUANTUM-CHEMICAL SIMULATION OF THE GUANOSINE - GUANOSINE INTERACTION IN HYDROGEL

SAKHAROV READINGS 2022: ENVIRONMENTAL PROBLEMS OF THE XXI CENTURY Part 1, 2022
Quantum-chemical simulation of interaction between guanosines molecules in water solution shows possibility of existing hydrogen bonds between NH2 and C=O groups of one molecule and atom O of 3'-ОН and atom H of 2'-ОН groups of other molecule, respectively. It was found that stability of hydrogel increased with the increasing of guanosine concentration

Penicillin interaction with guanosine

Biochemical and Biophysical Research Communications, 1972
Abstract Because of the widespread use of penicillins as antibacterial agents, the question of how penicillin affects the function and structure of nucleic acids becomes of biological importance. This communication reports a nuclear magnetic resonance study which shows that penicillin-G interacts with guanosine in dimethyl sulfoxide and can break the

CONDENSATION OF TRIFORMYLMETHANE WITH GUANOSINE

Nucleosides, Nucleotides and Nucleic Acids, 2001
Guanosine has been reacted with triformylmethane (TFM) in refluxing pyridine. Four different products, 4-7, were isolated by preparative RP-HPLC, and characterized by 1H and 13C NMR and UV spectroscopy and mass spectrometry. One of the products. the cyclic 1:1 adduct 4, is a stable cyclic carbinolamine formed probably by cyclization of the expected ...

UV‐Light‐Induced Hydrogen Transfer in Guanosine–Guanosine Aggregates

Chemistry – A European Journal, 2013
AbstractAggregates of a lipophilic guanine (G) derivative have been studied in n‐hexane by femtosecond‐to‐microsecond UV‐visible broadband transient absorption, stationary infrared and UV‐visible spectroscopy and by quantum chemical calculations. We report the first time‐resolved spectroscopic detection of hydrogen transfer in GG aggregates, which ...

Tautomerism and Protonation of Guanosine

Science, 1963
Guanosine has been demonstrated, by infrared and nuclear magnetic resonance spectroscopy, to have a keto-amino structure in neutral aqueous solution and to undergo protonation at N 7 in acid solution.

Reactions of formaldehyde with guanosine

Toxicology Letters, 1981
Formaldehyde reacted with guanosine and the products were assayed using fluorescence spectroscopy at different pHs. The reaction products were fluorescent in alkali only as was found with commercial N-2 methylguanosine. Thus, formaldehyde appeared to react with N-2 of guanosine. The reaction was completed with 30s both at 0 degrees C or at 21 degrees C.
