COA Handling Instructions

Tanespimycin (17-AAG) est un inhibiteur puissant de HSP90 avec un IC50 de 5 nM, ayant une affinité de liaison 100 fois plus élevée pour la tumeur HSP90 dérivé de cellule que HSP90 dérivé de cellule normale. Tanespimycin épuise les cellules STK38/NDR1 cellulaires et réduit l'activité des kinases STK38. Tanespimycin régule également à la baisse l'expression stk38 du gène.

Tanespimycin (17-AAG) is a potent HSP90 inhibitor with an IC50 of 5 nM, having a 100-fold higher binding affinity for tumour cell derived HSP90 than normal cell derived HSP90. Tanespimycin depletes cellular STK38/NDR1 and reduces STK38 kinase activity. Tanespimycin also downregulates the stk38 gene expression.

    Description

    Tanespimycin (17-AAG) is a potent HSP90 inhibitor with an IC50 of 5 nM, having a 100-fold higher binding affinity for tumour cell derived HSP90 than normal cell derived HSP90[1][5]. Tanespimycin depletes cellular STK38/NDR1 and reduces STK38 kinase activity. Tanespimycin also downregulates the stk38 gene expression[3].

    In Vitro

    Tanespimycin causes the degradation of HER2, Akt, and both mutant and wild-type AR and the retinoblastoma-dependent G1 growth arrest of prostate cancer cells. Tanespimycin inhibits prostate cancer cell lines with IC50s ranged from 25-45 nM (LNCaP, 25 nM; LAPC-4, 40 nM; DU-145, 45 nM; and PC-3, 25 nM)[1].
    Tanespimycin (0.1-1 μM) induces a nearly complete loss of ErbB2 on ErbB2-overexpressing breast cancer cells[2]. Tanespimycin inhibits cell growth and induces G2/M cell cycle arrest and apoptosis in CCA cells together with the down-regulation of Bcl-2, Survivin and Cyclin B1, and the up-regulation of cleaved PARP[3].

    In Vivo

    Tanespimycin (25-200 mg/kg, i.p.) causes a dose-dependent decline in AR, HER2, and Akt expression in prostate cancer xenografts. Tanespimycin treatment at doses sufficient to induce AR, HER2, and Akt degradation results in the dose-dependent inhibition of androgen-dependent and -independent prostate cancer xenograft growth without toxicity[1].
    Tanespimycin (60 mg/kg) with Rapamycin (30 mg/kg) inhibits A549 and MDA-MB-231 tumor growth and effects tumor cures in MDA-MB-231 tumor-bearing animals by tail vein injection[4].

    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

    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% Corn Oil

      Solubility: ≥ 5 mg/mL (8.54 mM); Clear solution

      This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Cell Assay
    [1]

    For the Alamar Blue proliferation assay, 2-4×103 cells are plated in 96-well plates. Later (48 h), cells are treated with Tanespimycin for 96 h or 0.01% DMSO as control. On day 4, Alamar Blue viability assay is performed as described elsewhere. IC50 and IC90s are calculated as the doses of Tanespimycin required to inhibit cell growth by 50 and 90%, respectively. Cell cycle distribution is assayed as described previously with a Becton Dickinson fluorescence-activated cell sorter and analyzed by the Cell Cycle Multicycle system.

    Animal Administration
    [1]

    Tanespimycin is dissolved in an EPL vehicle. To aid in the identification of an optimal dose and schedule, nontumor bearing mice are treated by i.p. injection with 25-200 mg/kg of Tanespimycin 5 days/week for 3 weeks or by the EPL vehicle alone. Serum samples are taken from each group, and equal volumes are pooled on days 5, 10, and 15 of treatment for serum chemistry and liver function analysis. At sacrifice, plasma samples are collected for complete blood count. A gross necropsy is performed on all of the mice, and a complete necropsy, including histopathology, is performed on 1 animal/group.

    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.
