일반 설명

1-Methyluracil is of special importance in biochemistry, since uracil attaches ribose in ribonucleic acid (RNA) just precisely at the N1 atom. H-bond complex formation between 1-methyluracil and glycine has been investigated by theoretical calculations and FT-IR spectroscopy in Ar matrices. It forms 1:1 complexes with 9-ethyl-8-bromo-2,6-diaminopurine and the complex structure has been determined by three-dimensional X-ray diffraction methods.

Theoretical simulation of the band shape and fine structure of the N-H(D) stretching band is presented for 1-methyluracil and its deuterated derivative taking into account anharmonic coupling between the high-frequency N-H(D) stretching and the low-frequency N...O stretching vibrations, resonance interaction

The hydration of nucleotide bases of m9Ade(A), m1Ura(U) and a complementary pair A.U was studied by field ionization mass-spectrometry at room and low (170 K) temperatures in vacuum. Enthalpies of A.U-pair formation and its monohydrate A.U(H2O) were measured using temperature

As far as fundamental knowledge is concerned, the methyl derivatives of uracil can be considered as the simplest objects for studying the structural effects due to the substitution in the pyrimidyne nucleobases. From this point of view, 1-methyluracil is of
