2'-O-Methylguanosine Chemical Properties,Uses,Production

Description

2'-O-Methylguanosine is a nucleoside that contains a 2'-O-methyl group at the 2' position of the ribose. It is a component of many nucleic acids and is usually found as a minor component in RNA. 2'-O-Methylguanosine has been shown to be an inhibitor of DNA polymerase and an activator of RNA polymerase, which may be due to its ability to form hydrogen bonds with the phosphate backbone.

Chemical Properties

White Solid

Uses

Guanosine analog. Used for preparation of nucleoside derivatives as inhibitors of RNA-dependent RNA viral polymerase.

Definition

ChEBI: Guanosine with the hydrogen on the hydroxyl at position C-2' substituted with a methyl group.

Synthesis

8-Thio-2'-O-methylguanosine (1 mmole) is dissolved in water and the solution is heated at reflux with Raney nickel for 6 h. The product is isolated by passing the solution through a short pad of celite and is further crystallizing to afford 2'-O-methylguanosine.
2'-O-Methylguanosine

Physiological effects

2'-O-Methylguanosine is a modified nucleoside, it is thought to stabilize the structure of the tRNA.2'-O-Methylguanosine can also be found in rRNA. Normal and modified nucleosides, including 2'-O-methylguanosine, have been shown to be secreted by a natural suppressor cell line and induce apoptosis in K562/Molt4 target cells.
