Brassinolide, a plant growth modulator and a plant hormone, is a sterol compound first isolated from pollen of rape (Brassica napus L.). It might facilitate cell division and stem cell elongation. Brassinolide may also have anticancer properties. It might cause PC-3 cells to exhibit a time- and concentration-dependent cytotoxicity. The predominant mode of cell death seemed to be apoptosis. Treatment with brassinolide may boost Caspase-3 activity. According to Western blot analyses, treatment with brassinolide led to a time-dependent reduction in the expression of the anti-apoptotic protein Bcl-2. Therefore, brassinolide might cause cytotoxicity in PC-3 cells by inducing apoptosis. Therefore, brassinolide may be a promising candidate for the treatment of prostate cancer.

A naturally occurring plant hormone called brassinolide encourages growth, boosts crop yields for grains and fruits, and makes plants more resilient to drought and cold temperatures. In PC-3 cells, brassinolide may cause a cytotoxicity that is dependent on both time and concentration. A time-dependent reduction in the expression of the anti-apoptotic protein Bcl-2 and a significant accumulation in the G2/M phase of the cell cycle are brought on by brassinolide treatment[1]. The level of protein expression of p53 in resistant cells is higher than that of sensitive cells. After Brassinolide treatment, the expression of p53 in CCRF-VCR cells restored to the level of sensitive cells. Brassinolide can effectively reverse the resistance of CCRF-VCR cells by inhibiting the effusion of drug transported by P-glucoprotein. To down regulate the abnormal expression of p53 maybe one of the mechanisms of reversing MDR for Brassinolide. MTT method is used to detect the resistant factor of resistant cell line and the reversing fold after addition of Brassinolide. The intracellular accumulation of rhodamine 123, a fluorescent dye transported by P-glycoprotein is detected by flow cytometry, the catalytic activity of topoisomerase II is assessed by Sulliven method to find the effect of Brassinolide on resistance. The protein expression of p53 is measured using Western blotting in the sensitive cells and resistant cells to explore the effect of Brassinolide. |

MTT method is used to detect the resistant factor of resistant cell line and the reversing fold after addition of Brassinolide. The effect of Brassinolide on resistance is determined by flow cytometry, which measures the intracellular accumulation of rhodamine 123, a fluorescent dye transported by P-glycoprotein. To investigate the impact of brassinolide, Western blotting is used to quantify the protein expression of p53 in both resistant and sensitive cells.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
