Incorporation of 2'-deoxy-5-(trifluoromethyl)uridine and 5-cyano-2'-deoxyuridine into DNA.

چکیده
In an attempt to synthesize DNA containing 2'-deoxy-5-(trifluoromethyl)uridine (1) using previously published protocols, we found that the trifluoromethyl group converted into a cyano group, resulting in DNA containing 5-cyano-2'-deoxyuridine (3). We show that nucleoside 1 can be incorporated into DNA using phosphoramidite 2 in combination with acetyl-protected deoxycytidine and phenoxyacetyl-protected purine phosphoramidites. Replacing thymidine in DNA with 1 caused a slight decrease in DNA duplex stability at pH 6.9.

Biological effects of 5-carboxy-2'-deoxyuridine: hydrolysis product of 5-trifluoromethyl-2'-deoxyuridine.
5-Carboxy-2'-deoxyuridine (5-COOH-2'-dUrd) is a product of the base-catalyzed hydrolysis of 5-trifluoromethyl-2'-deoxyuridine. Hydrolysis of 5-trifluoromethyl-2'-deoxyuridine to 5-COOH-2'-dUrd in phosphate-buffered saline was kinetically first order and was pH dependent. At 37 degrees C and pH 7.0, 7.5, and 8.0, hydrolysis occurred with rate constants of 4.19 x 10(-5), 9.30 x 10(-5), and 1.61 x...
متن کاملUnexpected formation of 2 -deoxy-N3-(3,3,3-trifluoro-1-propenyl)uridine via a Michael-type addition to 3,3,3-trifluoropropyne
Reaction of 3,3,3-trifluoropropyne with 2 -deoxy-5-iodouridine under conditions that have previously been used to prepare 5-alkynyl-2 -deoxyuridine derivatives gave 2 -deoxy-N3-(3,3,3-trifluoro-1-propenyl)uridine. This unexpected alkylation is a result of a Michael-type addition of N3 on the pyrimidine base to the electron deficient trifluoropropyne. © 2003 Elsevier Ltd. All rights reserved. Th...
متن کاملStereospecific syntheses of 3'-deuterated pyrimidine nucleosides and their site-specific incorporation into DNA.
[reaction: see text] 2'-Deoxy-3'-deutero pyrimidines have been synthesized in high yields and incorporated into deoxyoligonucleotides using standard phosphoramidite chemistry. A key synthetic step is a stereospecific reduction of 3'-keto nucleosides using sodium triacetoxyborodeuteride to give 3'-deuterated thymidine and 2'-deoxy uridine nucleosides. Conversion of the corresponding phorphoramid...
متن کاملCytotoxicity and Mode of Action of 5-Azacytidine on LI 210 Leukemia1
This study attempts to determine the primary actions of 5-azacytidine (5-azaCR) on L1210 leukemia. This agent was cytotoxic toward L1210 cells growing in culture with 50 and 90% inhibition dose values of 0.019 and circa 0.15 jug/ml, respectively. 5-AzaCR inhibits the incorporation of tritiated thymidine or deoxyadenosine into DNA to a greater extent than it inhibits the incorporation of tritiat...
متن کاملSimultaneous Detection of FISH Signals and Bromo-Deoxyuridine Incorporation in Fixed Tissue Cultured Cells
FISH (Fluorescence in situ hybridization) is a powerful technique that detects and localises specific DNA sequences on metaphase chromosomes, interphase nuclei or chromatin fibres. When coupled to BrdU (5-Bromo 2-deoxy-uridine) labeling of newly replicated DNA, the replication properties of different DNA sequences can be analysed. However, the technique for the detection of BrdU incorporation i...
