The 13C-NMR signals were found to be at 191.97 (benzoyl, C=O), 164.10 (pyrimidine
, C=O), 160.38-114.08 (aromatic C), 56.09-55.65 (2CH3O-), 11.73 ppm (CH3-).
Such correlations (Figure 2) correspond to the protons of the phenyl group in position 2 of the pyrimidine
However, the synthesis of chromophore c was performed using Chromophore a and 2-amino pyrimidine
through a diazo coupling reaction with a prime aim to improve the high optical transparency, good thermal stability and good planarity.
(10) reported 62% of mucosal toxicity, similar to the 51.2% found in our series with use of pyrimidine
Pathway enrichment and topology analysis identified enrichment in purine, pyrimidine
, inositol phosphate, and branched-chain amino acid metabolism in addition to lysine degradation in both BMM and MDM.
Dihydropyrimidinase is a key enzyme for pyrimidine
catabolism [1, 2].
Decitabine is a pyrimidine
analogue of the nucleoside cytidine .
derivatives Uracil and Thymine are an integral part of RNA and DNA, respectively.
UVB light passing through keratinocytes can cause DNA damage by inducing adjacent pyrimidine
bases to form pyrimidine
Specifically, nucleic acids or their constituent purine or pyrimidine
bases act as internal microbial markers of microbial protein synthesis .
The imine proton is observed at 8.27 ppm and the pyrimidine
(C7) proton is found at 6.99 ppm.
Nucleosides including purine and pyrimidine
nucleosides are reported to possess many interesting forms of biological and pharmacological activity, such as anti-infective activity , antiviral activity , anticancer activity , antioxidation activity , and immunological stimulation , which implies a need for large-scale production of nucleosides.
