Description

TFEB activator 1 is an orally effective, mTOR-independent activator of TFEB. TFEB activator 1 significantly promotes the nuclear translocation of Flag-TFEB with an EC50 of 2167 nM. TFEB activator 1 enhances autophagy without inhibiting the mTOR pathway and has the potential for neurodegenerative diseases treatment[1].

IC50 & Target

EC50: 2167 nM (Flag-TFEB nuclear translocation)[1]
In Vitro

TFEB activator 1 (Compound C1) activates TFEB (transcription factor EB) by directly binding to TFEB and promotes its entry into the nucleus, without affecting TFEB phosphorylation or inhibiting the activities of MTOR and MAPK1/ERK2-MAPK3/ERK1[1].
? TFEB activator 1 (1 μM; for 12 h) significantly increases the levels of LC3B-II, the lipidated and phagophore- or autophagosome-associated form of MAP1LC3B/LC3B (microtubule-associated protein 1 light chain 3 β) in N2a cells[1].
? TFEB activator 1 (0.2-1 μM) dose-dependently increases the levels of LC3-II and SQSTM1/p62 (sequestosome 1) in N2a cells[1].

Incubation Time: 12 hours
Result: Treatment dose-dependently increased the levels of LC3-II and SQSTM1/p62 (sequestosome 1).
In Vivo

The medium lethal dose (LD50) value of TFEB activator 1 (Compound C1) is 175 mg/kg in the acute toxicity assay (single-dose i.v. tail vein injection; in rats) [1].
? Short-term oral administration of TFEB activator 1 (low dosage 10 mg/kg and high dosage 25 mg/kg; for 24 h) dose-dependently increases the expression of LC3B-II and TFEB in the liver, frontal cortex and striatum of the brain[1].
? Chronic administration of TFEB activator 1 (10 mg/kg per day; orally administered by gavage) activates TFEB and enhances autophagy in rat brains[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% Corn Oil

    Solubility: ≥ 6.25 mg/mL (21.23 mM); Clear solution

    This protocol yields a clear solution of ≥ 6.25 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 (62.5 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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:  50% PEG300    50% Saline

    Solubility: 4 mg/mL (13.59 mM); Suspended solution; Need ultrasonic

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.
