Tubercidin

Tubercidin (7-Deazaadenosine) is an adenosine analog, is an antibiotic obtained from Streptomyces tubercidicus.Target: AntibacterialTubercidin inhibits the growth of Streptococcus faecalis by 50 % at a concentration of 20 nM. Tubercidin is not subject to cleavage by adenosine phosphorylase or to deamination by adenosine deaminase. The antibiotic served as a substrate for numerous enzymes involved in the anabolism of adenosine, as demonstrated by its incorporation into RNA and DNA, and by
Tubercidin is an N-glycosylpyrrolopyrimidine that is adenosine in which the in the 5-membered ring that is not attached to the ribose moiety is replaced by a carbon. Tubercidin is produced in the culture broth of Streptomyces tubericidus. It has a role as an antineoplastic agent, a bacterial metabolite and an antimetabolite. It is a N-glycosylpyrrolopyrimidine, a ribonucleoside and an antibiotic antifungal agent.|An antibiotic purine ribonucleoside that readily substitutes for adenosine in the biological system, but its incorporation into DNA and RNA has an inhibitory effect on the metabolism of these nucleic acids.|Tubercidin is an antibiotic and adenosine analog isolated from the bacterium Streptomyces tubercidicus with potential antineoplastic activity. Tubercidin is incorporated into DNA and inhibits polymerases, thereby inhibiting DNA replication and RNA and protein synthesis. This agent also exhibits antifungal and antiviral activities. (NCI04)
