Application
6-Azauracil has been used as a transcriptional inhibitor to study its effects on the deletion of termination and polyadenylation protein (Tpa1) and Mag1 on cell viability. It has also been used as an orotidine-5′-monophosphate decarboxylase (OMPdecase) inhibitor in minimal media for determining the OMPdecase activity.
Biochem/physiol Actions
6-Azauracil (6-AU) is a pyrimidine analog of uracil and exhibits antitumor activity. It inhibits the growth of various microorganisms by depleting intracellular guanosine triphosphate (GTP) and uridine triphosphate (UTP) nucleotide pools.
