Quantification of cell turnover kinetics using 5-bromo-2'-deoxyuridine.
5-Bromo-2'-deoxyuridine (BrdU) is frequently used to measure the turnover of cell populations in vivo. However, due to a lack of detailed mathematical models that describe the uptake and loss of BrdU in dividing cell populations, assessments of cell turnover kinetics have been largely qualitative rather than quantitative. In this study, we develop a mathematical framework for the analysis of Br...
متن کاملEvaluation of (5R,6R)-5-Bromo-6-Ethoxy-5-Ethyl-5,6-Dihydro-2\'- Deoxyuridine as a Brain-Targeted Prodrug of 5-Ethyl-2\'- Deoxyuridine
(+)-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 homogena...
متن کاملDetection of S-phase cell cycle progression using 5-ethynyl-2'-deoxyuridine incorporation with click chemistry, an alternative to using 5-bromo-2'-deoxyuridine antibodies.
The 5-bromo-2'-deoxyuridine (BrdU) labeling of cells followed by antibody staining has been the standard method for direct measurement of cells in the S-phase. Described is an improved method for the detection of S-phase cell cycle progression based upon the application of click chemistry, the copper(I)-catalyzed variant of the Huisgen [3+2] cycloaddition between a terminal alkyne and an azide....

متن کاملTeratological evaluation of 5-fluorouracil and 5-bromo-2-deoxyuridine on hamster fetuses.
A single intraperitoneal injection of 5-bromo-2-deoxyuridine (BUDR) between days 9 and 11 and a single intramuscular injection of 5-fluorouracil (FU) between days 8 and 11 of gestation were teratogenic in hamster. The malformation frequencies were related to the dose and time of BUDR and FU treatment but the pattern and types of malformations and their frequencies were different. BUDR showed lo...
