We have synthesized 2'-5' linked oligomers from 8-substituted adenosine-5'-phosphorimidazolides using uranyl ion catalyst. 8-amino derivative, as highly susceptible to hydrolysis, gave short chained oligomers in a low yield, while the rest of 8-substituted or unsubstituted derivatives gave the corresponding oligomers in high yields. Properties of 8-substituted 2'-5' oligomers were studied applying spectrometer and through enzymatic digestion.

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
D009843 Oligoribonucleotides A group of ribonucleotides (up to 12) in which the phosphate residues of each ribonucleotide act as bridges in forming diester linkages between the ribose moieties.
D011108 Polymers Compounds formed by the joining of smaller, usually repeating, units linked by covalent bonds. These compounds often form large macromolecules (e.g., BIOPOLYMERS; PLASTICS). Polymer

D000241 Adenosine A nucleoside that is composed of ADENINE and D-RIBOSE. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. Adenocard,Adenoscan
D014501 Uranium A radioactive element of the actinide series of metals. It has an atomic symbol U, atomic number 92, and atomic weight 238.03. U-235 is used as the fissionable fuel in nuclear weapons and as fuel in nuclear power reactors.
