Herpes simplex virus type 1 uracil-DNA glycosylase: isolation and selective inhibition by novel uracil derivatives.
We have purified Herpes simplex type 1 (HSV1) uracil-DNA glycosylase from the nuclei of HSV1-infected HeLa cells harvested 8 h post-infection, at which time the induction of the enzyme is a maximum. The enzyme has been shown to be distinct from the host enzyme, isolated from HeLa cells, by its lack of sensitivity to a monoclonal antibody to human uracil-DNA glycosylase. Furthermore, several ura...
متن کاملNew Boron-Nitrogen Analogues of Uracil Derivatives [1]
The reaction o f N.N'-dim ethylurea with l,5-dim ethyl-2,4-bis-(dim ethylam ino)-l,5-diaza-2,4-dibora-3-oxacyclohexan-6-one (2) in the melt proceeds with condensation of the urea to yield two major products: the acid l,3,5-trim ethyl-2-hydroxy-l,3,5-triaza-2-boracyclohexa-4,5-dione (la); and a mixture of the methylammonium (4a) and dimethylammonium salt (4b) of the anion [{C H 3N («-C O N C H 3...
متن کاملSynthesis and carbonic anhydrase inhibitory properties of novel uracil derivatives.
Carbonic anhydrase (CA) inhibitors are valuable molecules based on several therapeutic applications, including antiglaucoma activity. In the present study, inhibition of two human cytosolic carbonic anhydrase isozymes I and II with some uracil derivatives (3-9) were investigated. Compounds 3-9 showed KI values in the range of 10.83-464 μM for hCA I and of 28.88-778.5 μM against hCA II, respecti...
متن کاملIncrease in the photoreactivity of uracil derivatives by doubling thionation.
The ability of 4-thiouracil to strongly absorb UVA radiation and to populate a reactive triplet state in high yield has enabled its use as a versatile photocrosslinker for nearly 50 years. In this contribution, we present a detailed spectroscopic and photochemical investigation of the 2-thiouracil, 4-thiouracil, and 2,4-dithiouracil series in an effort to further advance this chemistry and to s...
