The Uses of TUBERCIDIN
Tubercidin is a nucleoside metabolite first isolated from Streptomyces tubericidus. Tubercidin, like other nucleosides, is a broad spectrum, potent chemotherapeutic agent active against viruses, bacteria, fungi, protozoans and tumours. Tubercidin acts at a diverse range of sites, such as RNA processing, nucleic acid and protein synthesis, and acts as a nucleoside mimic of adenosine.
What are the applications of Application
Tubercidin is an inhibitor of multiple metabolic processes such as RNA processing, nucleic acid synthesis, & protein synthesis
Definition
ChEBI: 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.
Biological Activity
tubercidin is an adenosine analog antibiotic agent.nucleoside antibiotics are a family of natural products with various biological functions. their biosynthesis is a complex process via multistep enzymatic reactions.
in vitro
previous study showed that tubercidin alone had a dose-dependent inhibitory effect on myeloid and erythroid human bone marrow progenitor cells. bfu-e were more sensitive at higher doses of tubercidin than cfu-gm. the 99% complete inhibition of bfu-e colonies was observed at 10 nm tubercidin, whereas complete inhibition of cfu-gm occurred at 100 nm [1].
in vivo
animal toxicity study showed that four successive daily injections of tubercidin at 5 mg/kg per day could produce 100% mouse mortality within 3 to 5 days, with massive peritonitis and intestinal obstruction. in addition, coadministration of nbmpr-p at 25 mg/kg per day could protect the mice from the tubercidin lethality and allow the repetition of the regimen for a second time with 100% survival [1].
Purification Methods
7-Deazaadenosine forms needles from hot H2O. It is soluble in H2O (0.33%), MeOH (0.5%) and EtOH (0.05%). It has UV max at 270nm ( 12,100) in 0.001N NaOH. The picrate has m 229-231o(dec).
