The protected 5-(2-amino-2-deoxy-beta-D-glucopyranosyloxymethyl)-2'- deoxyuridine phosphoramidite 15 has been prepared from uridine in 12 steps. When incorporated into oligodeoxyribonucleotides the novel nucleoside analog 5 leads to decreased binding affinity. This decrease is larger with a complementary RNA-strand than with a DNA complement.

UI MeSH Term Description Entries
D009841 Oligonucleotides Polymers made up of a few (2-20) nucleotides. In molecular genetics, they refer to a short sequence synthesized to match a region where a mutation is known to occur, and then used as a probe (OLIGONUCLEOTIDE PROBES). (Dorland, 28th ed) Oligonucleotide
D003857 Deoxyuridine 2'-Deoxyuridine. An antimetabolite that is converted to deoxyuridine triphosphate during DNA synthesis. Laboratory suppression of deoxyuridine is used to diagnose megaloblastic anemias due to vitamin B12 and folate deficiencies. (beta 1-(2-Deoxyribopyranosyl))thymidine
D013696 Temperature The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms. Temperatures
