Cirsiliol is a potent and selective 5-lipoxygenase inhibitor and a competitive low affinity benzodiazepine receptor ligand.
In concentrations from 0.01 to 300 μM, cirsiliol causes concentration-dependent relaxation of rat isolated ileum. Cirsiliol may inhibit Ca2+ influx but stimulates Ca2+ release from intracellular stores[1]. Treatment with rhamnetin or cirsiliol reduces the proliferation of NSCLC cells through the suppression of radiation-induced Notch-1 expression[2].
In xenograft mouse model, tumor volume is significantly reduced by combinational treatment with irradiation and rhamnetin or cirsiliol compared with irradiation alone[2].

Cell experiment: | NSCLC, NCI-H1299, NCI-H460, WI-26 VA4 and MRC-5 cell lines are exposed to a single dose of γ-rays. Cells are then treated with rhamnetin and cirsiliol (5, 10, 15, 20, 25 μM) dissolved in DMSO for 4 h[2]. |
Animal experiment: | Mice[1]BALB/c athymic nude mice are injected with 2×106 NCI-H1299 cells. When the tumor has acquired a minimal volume of 200 mm3, DMSO or Cirsiliol (200 μg/kg body weight) is administered intraperitoneally every day for 25 days. The animals are also irradiated with 10 Gy once a week for 3 weeks. On day 25, the tumors are excised and subjected to further analyses[1]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
