COA Handling Instructions

Tuberculine (7-déazadénosine) est un antibiotique obtenu à partir de Streptomyces tubercidicus. Tuberculine inhibe la croissance de Streptococcus faecalis (8043) avec un IC50 de 0,02 μM. Tuberculine inhibe les polymérases en incorporant l'ADN ou l'ARN, inhibant ainsi la réplication de l'ADN, la synthèse d'ARN et de protéines.Tuberculine est un inhibiteur faible de l'adénosine phosphorylase et interfère avec la phosphorylation de l'adénosine et de l'AMP.

Tubercidin (7-Deazaadenosin) ist ein Antibiotikum, das aus Streptomyces tubercidicus gewonnen wird. Tubercidin hemmt das Wachstum von Streptococcus faecalis 8043 mit einem IC50 von 0,02 μM. Tubercidin hemmt Polymerasen durch Einbau von DNA oder RNA, wodurch die DNA-Replikation, RNA- und Proteinsynthese gehemmt wird. Tubercidin ist ein schwacher Inhibitor der Adenosinphosphorylase und stört die Phosphorylierung von Adenosin und AMP.

Description

Tubercidin (7-Deazaadenosine) is an antibiotic obtained from Streptomyces tubercidicus. Tubercidin inhibits the growth of Streptococcus faecalis (8043) with an IC50 of 0.02 μM[1]. Tubercidin inhibits polymerases by incorporating DNA or RNA, thereby inhibiting DNA replication, RNA and protein synthesis[2]. Tubercidin is a weak inhibitor of adenosine phosphorylase, and interferes with the phosphorylation of adenosine and AMP[1]. Tubercidin has antiviral activity[2].

In Vitro

Tubercidin (7-Deazaadenosine) (0-10 nM; 14 days) has a dose-dependent inhibitory effect on myeloid and erythroid human bone marrow progenitor cells, and the IC50s of tubercidin are 3.4 nM and 3.7 nM for CFU-GM and BFU-E, respectively[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (9.39 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (9.39 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
