Skeletal Editing of Pyrimidines to Pyrazoles by Formal Carbon Deletion

open access: yesJournal of the American Chemical Society, 2022
A method for the conversion of pyrimidines into pyrazoles by a formal carbon deletion has been achieved guided by computational analysis. The pyrimidine heterocycle is the most common diazine in FDA-approved drugs, and pyrazoles are the most common ...

Research developments in the syntheses, anti-inflammatory activities and structure–activity relationships of pyrimidines

open access: yesRSC Advances, 2021
Pyrimidines are aromatic heterocyclic compounds that contain two nitrogen atoms at positions 1 and 3 of the six-membered ring. Numerous natural and synthetic pyrimidines are known to exist.

Studies in pyrimidine metabolism [PDF]

open access: greenJournal of Biological Chemistry, 1920
By partial hydrolysis of yeast nucleic acid, preparations containing pyrimidines as the only nitrogenous constituents were prepared and administered to rabbits. Uracil nucleoside when administered per os, subcutaneously or intraperitoneally caused an increased excretion of urea often much more than enough to account for the nitrogen administered.

A Search for Interstellar Pyrimidine [PDF]

open access: yesMon.Not.Roy.Astron.Soc.345:650,2003, 2003
We have searched three hot molecular cores for submillimeter emission from the nucleic acid building-block pyrimidine. We obtain upper limits to the total pyrimidine (beam-averaged) column densities towards Sgr B2(N), Orion KL and W51 e1/e2 of 1.7E+14 cm^{-2}, 2.4E+14 cm^{-2} and 3.4E+14 cm^{-2}, respectively.
