• Chemische Eigenschaften

  White crystal

• Verwenden

  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.

• 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.

• Biologische Aktivität

  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].

• IC 50

  3.4 and 3.7 nm for granulocyte-macrophage cfu (cfu-gm) and erythroid burst-forming units (bfu-e), respectively
