Cyasterone
Based on 3 publication(s) in Google Scholar
Cyasterone, a natural EGFR inhibitor, mainly isolated from Ajuga decumbens Thunb (Labiatae). Cyasterone manifests anti-proliferation effect by induced apoptosis and cell cycle arrests. Cyasterone may serves as a therapeutic anti-tumor agent against human tumors.

生物活性
IC50: EGFR[1]
Cyasterone exerts cytotoxicity on multiple cell lines: HeLa (IC50=77.24 μg/ml); HepG-2 (IC50=52.03 μg/ml); MCF-7 (IC50=82.07 μg/ml) and MCF-7 (IC50=82.07 μg/ml). And It has none cytotoxicity (IC50>400 μg/ml) on 3 types of carcinoma (HT-29, Caco-2, T47D) and 1 type of normal (NIH 3T3) cell lines[1]. Cyasterone (0-60 μg/ml; 48 hours) causes a significantly decreasing of the cell proliferation. It inhibits cell growth as a dose-dependent manner, exhibits IC50 values of 38.50 μg/ml and 32.96 μg/ml, respectively[1]. Cyasterone (0-60 μg/ml; 24 hours) decreases p-EGFR, p-MEK, and p-mTOR as a dose-dependent manner in A549 cells, it affects the MAPK signaling pathway activities[1].

溶剤 & 溶解度
DMSO : 100 mg/mL (192.07 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

濃度 (開始) × 体積 (開始) = 濃度 (終了) × 体積 (終了)
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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.80 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
