Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	3.3mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 66 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil	3.3mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 66 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

SRI-011381 (C381) is a novel agonist of the TGF-beta signaling pathway for treatment of Alzheimer's disease.C381 physically targets the lysosome, promotes lysosomal acidification, increases breakdown of lysosomal cargo, and improves lysosome resilience to damage.

Targets

TGF-β ^[1]

In vitro

SRI-011381 partially reverses the effect of sodium ferulate (SF) on the expression of fibrosis-related proteins, by increasing TGF-β1, NALP3, collagen-1, and α-SMA expression.^[2]

In vivo

SRI-011381, a small-molecule agonist of TGFβ signaling, has no effect on outflow tract (OFT) expansion in zebrafish, suggesting that hyperactivation of TGFβ signaling is not sufficient to induce aneurysm.^[3]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines pulmonary fibroblasts of silicosis mouse model Concentrations 10 µM Incubation Time -- Method The tissues are extracted in a sterile environment, rinsed in PBS 3 times, and then cut into 1-mm³ tissue blocks. After repeated digestion with 0.25% trypsin at 37 ℃, the histolysate is evenly spread in a 10-cm petri dish. A high-glucose medium containing 10% fetal bovine serum, penicillin, and streptomycin is added to the petri dish. The cells are cultured in an incubator, and the medium is exchanged every 2-3 days. When the cells reached 80-90% confluence, they are passaged according to the ratio of 1: 3, and the fifth passage cells are taken for experimental study. Pulmonary fibroblasts are identified using anti-vimentin antibody with fluorescent secondary antibodies under a fluorescence microscope. For in vitro experiments, a range of concentrations of SF solution (0.04, 0.1, 0.18 and 0.28 mg/mL) are prepared for the treatment of fibroblasts. A 10 μM SRI-011381 solution is used for the activation of TGF-β1 signaling.
