5-Ethyl-2'-deoxyuridine (EDU) is a potent and selective inhibitor of the replication of herpes simplex virus type 1 (HSV-1) and 2 (HSV-2), which is currently being pursued for the topical treatment of HSV-1 and HSV-2 infections in humans. Using [4-14C]EDU as the radiolabeled analogue of EDU, it was ascertained that, at antivirally active doses, EDU is phosphorylated to a much greater extent by ...

Whether you call it biochemistry, molecular pharmacology, or chemical biology, one thing we can agree on is that chemists have long sought to advance the biological sciences. Through development of reagents, instruments, algorithms, and technologies, chemistry brings to biology the ability to drill down to molecules, bonds and atoms—the scale of matter at which all living things converge on com...

Sodium hyaluronate-carboxymethylcellulose (HA/CMC) formulations are gels that effectively reduce postoperative adhesions in both animals and humans, when placed in the peritoneal or pelvic cavities concomitant with surgical manipulation. However, it has been suggested that the use of these products may increase the risk of peritoneal infection after contamination with intestinal contents during...

(+)-trans-(5r,6r)-5-bromo-6-ethoxy-5-ethyl-5,6-dihydro-2'-deoxyuridine [(5r,6r)-beedu], a po tential brain-targeted prodrug of 5-ethyl-2'-deoxyuridine (edu), was synthesized by the regiospecific addition of broet to the 5,6-olefinic bond of edu. (5r,6r)-beedu is more lipophilic (log p = 0.04) than edu (log p = -1.09). in vitro incubation of (5r,6r)-beedu with rat whole blood and brain...

(+)-Trans-(5R,6R)-5-bromo-6-ethoxy-5-ethyl-5,6-dihydro-2'-deoxyuridine [(5R,6R)-BEEDU], a potential brain-targeted prodrug of 5-ethyl-2'-deoxyuridine (EDU), was synthesized by the regiospecific addition of BrOEt to the 5,6-olefinic bond of EDU. (5R,6R)-BEEDU is more lipophilic (log P = 0.04) than EDU (log P = -1.09). In vitro incubation of (5R,6R)-BEEDU with rat whole blood and brain homogenate...

We previously defined macrophages harvested from the peritoneal cavity of nude mice with subcutaneous human pancreatic tumors as "tumor-educated-macrophages" (Edu) and macrophages harvested from mice without tumors as "naïve-macrophages" (Naïve), and demonstrated that Edu-macrophages promoted tumor growth and metastasis. In this study, Edu- and Naïve-macrophages were compared for their ability ...

Replication errors that are caused by mutagens are critical for living cells. The aim of the study was to analyze the distribution of a DNA replication pattern on chromosomes of the H. vulgare 'Start' variety using pulse 5-ethynyl-2'-deoxyuridine (EdU) labeling, as well as its relationship to the DNA damage that is induced by mutagenic treatment with maleic hydrazide (MH) and γ ray. To the best...

Correspondence Emergence of an Autochthonous and Community-Acquired NDM-1–Producing Klebsiella pneumoniae in Europe To the Editor—The recently identi-tified carbapenemase New Dehli metallo-b-lactamase (NDM-1) in-activates all b-lactams except az-treonam [1]. The corresponding gene that is usually plasmid-borne has spread mostly in Escherichia coli and Klebsiella pneumoniae [1, 2]. NDM-1 produce...

Legislative institutions structure and order the myriad topics addressed by legislators. Jointly considering both roll call votes and floor speech, we show that the contemporary US Senate is ordered around but two dimensions: one ideological and another capturing leadership. We characterize both word and vote choice in terms of the exact same ideal points and policy dimensions. These findings e...

We have developed a method to detect DNA synthesis in proliferating cells, based on the incorporation of 5-ethynyl-2'-deoxyuridine (EdU) and its subsequent detection by a fluorescent azide through a Cu(I)-catalyzed [3 + 2] cycloaddition reaction ("click" chemistry). Detection of the EdU label is highly sensitive and can be accomplished in minutes. The small size of the fluorescent azides used f...
