Autophinib is a potent, selective autophagy inhibitor with IC50s of 90 nM and 40 nM for starvation- and Rapamycin-induced autophagy, respectively. Autophinib is also an ATP competitive Vacuolar Protein Sorting 34 (VPS34) inhibitor with an IC50 of 19 nM. Autophinib inhibits autophagy induced by starvation or Rapamycin by targeting VPS34.

    Autophinib purchased from MedChemExpress. Usage Cited in: Cancer Sci. 2020 May; 111(5): 1542-1554.  [Abstract]

    Western blotting shows that the decreased protein expression of P62 in Per1‐OE SCC15 cells is remarkably increased after the addition of Autophinib, while the increased LC3BII/LC3BI ratio and Beclin1 expression are remarkably decreased.

    Description

    Autophinib is a potent, selective autophagy inhibitor with IC50s of 90 nM and 40 nM for starvation- and Rapamycin-induced autophagy, respectively. Autophinib is also an ATP competitive Vacuolar Protein Sorting 34 (VPS34) inhibitor with an IC50 of 19 nM. Autophinib inhibits autophagy induced by starvation or Rapamycin by targeting VPS34[1].

    IC50 & Target[1]

    Vps34

    19 nM (IC50)

    In Vitro

    Autophinib (0.01-1 μM) inhibits LC3 lipidation to form LC3-II in a dose-dependent manner in starved MCF7-LC3 cells. Consistent with inhibition of autophagic flux, Autophinib also inhibits p62 degradation by autophagy dose-dependently in MCF7-LC3 cells[1].
    Autophinib enhances cell death (EC50 of 264 nM) of starved cells as compared to fed cells, which occurred via the induction of apoptosis (EC50 of 234 nM) in MCF7 cells[1].

    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    90% (20% SBE-β-CD in Saline)

      Solubility: 0.5 mg/mL (1.44 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 0.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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.
    • Protocol 2

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

      Solubility: ≥ 0.5 mg/mL (1.44 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    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.
