Purines and pyrimidines are complementary bases of the genetic code. The roles of purines and their derivatives in cellular signal transduction and energy metabolism are well-known. In contrast, the roles of pyrimidines and their derivatives in cellular function remain poorly understood. In this study, the roles of uridine, a pyrimidine nucleoside, in liver metabolism are examined in mice. We r...
UNLABELLED BACKGROUND Imidazo[1,2-a]pyridines and pyrimidines are important organic fluorophores which have been investigated as biomarkers and photochemical sensors. The effect on the luminescent property by substituents in the heterocycle and phenyl rings, have been studied as well. In this investigation, series of 3-hydroxymethyl imidazo[1,2-a]pyridines and pyrimidines were synthesized an...
Early stud& with pyrimidines administered t.o animals established the fact that, these compounds arc metabolized (3, 4). Present concepts of the pathways of pyrimidine metabolism stem largely from the work of Cerecedo (4), in which he measured the changes in the urinary excretion of urea after feeding pyrimidines and related subst.ances. On the basis of these studies, he proposed an init.ial ox...
