In Vitro
mTOR inhibitor-8 (Compound 5e; 0.1-10 μM; 24 and 48 hours) suppresses the growth of A549 cells in a dose-dependent manner[1].
mTOR inhibitor-8 induces autophagy in an mTOR-dependent manner. mTOR inhibitor-8 (10 μM; 3-24 hours) induces autophagy in a time-dependent manner. The levels of LC3B-II are enhanced[1].
mTOR inhibitor-8 (10 μM; 3-24 hours) reduces the phosphorylation of RPS6KB1 (ribosomal protein S6 kinase) and EIF4EBP1 (eukaryotic translation initiation factor 4E-binding protein 1), two essential substrates of mTOR[1]

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.08 mg/mL (4.65 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.08 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 (20.8 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.

Autophagy
Autophagy is a process in which eukaryotic cells use lysosomes to degrade their own cytoplasmic proteins and damaged organelles under the regulation of autophagy related gene (Atg). Microtubule-associated proteins light chain 3 (LC3) is recognized as autophagy marker, which transfers from cytoplasmic LC3 (LC3-I) to membrane type (LC3-II). LC3-II/I ratio could be detected by Western Blot and fluorescence microscopy.

Lysosome and acidic-vesicle live-cell staining
Lysosome and acidic-vesicle live-cell staining detects acidic intracellular compartments by using membrane-permeant acidotropic probes that accumulate in low-pH vesicles, including lysosomes, late endosomes, autolysosomes, and acidic phagosomes. LysoTracker staining is commonly used as an intensity-based readout of acidic lysosomal compartment abundance or enlargement, while acridine orange produces green fluorescence in less concentrated compartments and red fluorescence after concentration-dependent accumulation in acidic vesicular organelles. Loss or reduction of acridine-orange red signal can be used as a readout of lysosomal membrane permeabilization or reduced acidic-vesicle integrity. This protocol is designed for live cultured cells and can be adapted for fluorescence microscopy, high-content imaging, plate-reader readout, or flow cytometry when the selected literature supports the readout. Because these dyes report acidotropic accumulation rather than lysosome identity alone,

Macroautophagy Solutions
Macroautophagy is a conserved lysosome-dependent degradation pathway in which cytoplasmic material is sequestered into double-membrane autophagosomes and delivered to lysosomes for degradation and recycling. The pathway supports cellular homeostasis during nutrient limitation, organelle stress, protein-aggregate accumulation, infection, differentiation, and tissue remodeling by coupling cargo sequestration, autophagosome maturation, lysosomal fusion, and degradation of cargo-derived macromolecules. The core molecular sequence includes initiation by nutrient- and stress-regulated autophagy machinery, autophagosome nucleation, LC3/ATG8-family conjugation to autophagosomal membranes, cargo selection through receptors such as SQSTM1/p62, autophagosome-lysosome fusion, and lysosomal degradation. LC3 was identified as a mammalian homolog of yeast Atg8 that localizes to autophagosomal membranes after processing, and p62/SQSTM1 was shown to connect ubiquitinated cargo with autophagic degradati
