Uracil Photoproducts from Uracil Irradiated in Ice
Science, 1969Two new products were isolated from uracil irradiated with ultraviolet light in frozen aqueous solution. As judged by mass, nuclear magnetic resonance, and ultraviolet and infrared spectra, one is a photopolymer, U 3 , and the structure of the other is probably 6-4′-[pyrimidin-2′-one]-uracil.

Tegafur is a prodrug of the antineoplastic agent fluorouracil, and is administered in a 1:4 molar ratio with the fluorouracil modulator uracil. Oral tegafur/uracil 300 mg/m(2)/day plus calcium folinate 75 or 90 mg/day for 28 days every 35 days was as effective as intravenous (IV) fluorouracil 425 mg/m(2)/day plus folinic acid 20 mg/m(2)/day for 5 days ...

Uracil-DNA Glycosylases and DNA Uracil Repair
1989Publisher Summary This chapter reviews the DNA uracil repair and uracil–DNA glycosylases (UDG). The major source of DNA uracil in prokaryotic and eukaryotic cells is transient incorporation of dUMP during replication. This replicative uracil is quickly repaired by UDG, apyramidinic/apurinic (AP) endonucleases, and other enzymes of excision repair ...

Science, 1962
Explorations in the pyrimidine series have led to the discovery of highly active herbicides, of which 3-butyl-6-methyluracil and 5-bromo-3-isopropyl-6-methyluracil are examples.

We investigate the photochemistry and photodissociation dynamics of uracil by two-colour photofragment Doppler spectroscopy and by two-colour slice imaging at excitation wavelengths between 268 and 235 nm. We observe the loss of a hydrogen atom upon excitation into the pipi* state.
