Customer Review

Based on 1 Customer Validation

Scoulerine ((-)-Scoulerine; Discretamine) hydrochloride is a multi-target inhibitor with anti-tumor and antioxidant activities. Scoulerine mainly targets the PI3K/Akt/mTOR signaling axis and α1D-adrenergic receptor, disrupts microtubule structure, and induces cell cycle arrest and apoptosis. Scoulerine effectively inhibits mitochondrial dehydrogenase activity, targets GABA receptors and BACE1, and suppresses the proliferation, migration, invasion, epithelial-mesenchymal transition and stem cell properties of cancer cells. Scoulerine also exhibits multiple pharmacological activities including anti-Plasmodium falciparum, antibacterial, antiemetic and antitussive effects, and regulates endoplasmic reticulum stress and mitochondrial function (modulates Bax, Bcl-2 and cytochrome c). Scoulerine is applicable to research related to leukemia, ovarian cancer, and colorectal cancer.

In Vitro

Scoulerine (1-50 μM; 72 h) exhibits antiproliferative activity against human lung cancer A549 cells, ovarian cancer A2780 cells, breast cancer SK-BR-3 cells, and MCF-7 cells. Low concentrations (1 μM, 5 μM) exert little effect or cause slight delay on cell proliferation, while high concentrations (10 μM, 20 μM, 50 μM) significantly inhibit cell proliferation^[2].
Scoulerine (2.5-20 μM; 24 h) induces apoptosis in Jurkat and MOLT-4 leukemia cells, with dose-dependent increases in both early and late apoptosis rates, and DNA fragmentation can be detected via TUNEL assay^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Stock Solution Working Solution

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 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.08 mg/mL (6.35 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.08 mg/mL (6.35 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
