产品描述 | Guanfacine hydrochloride (Intuniv) is a centrally acting antihypertensive agent with specificity towards ADRENERGIC ALPHA-2 RECEPTORS. |
靶点活性 | α2B-adrenoceptor:31 nM(Kd) |
细胞实验 | Cells (1 mL) are seeded into 24-well plates at a density of 1 × 105 cells/mL. Culture medium is replaced every two days until cells reached confluence. To investigate the potential influence of P-gp on guanfacine transport, intracellular accumulation of guanfacine is measured in LLC-PK1/MDR1 cells and P-gp-negative LLC-PK1 cells. Rhodamine6 g, a well-known P-gp substrate, is included as a positive control. After cells reach confluence, the culture medium is replaced by transport buffer for a 30-minute preincubation at 37°C. Transport buffer is then removed and the test compounds (5 μM rhodamine6 g, 5 μM guanfacine, or 50 μM guanfacine) are added, and an additional 60-minute incubation period commenced. Next, the solutions are discarded, and the cells are washed three times with ice-cold Dulbecco's phosphate-buffered saline and solubilized with 1% Triton X-100. Intracellular accumulation of rhodamine6 g is measured using a fluorescent microplate reader with a 530 nm excitation and a 580 nm emission wavelength, which is a well established method. Cellular retention of guanfacine is analyzed by the high-performance liquid chromatographic assay described below. The concentrations of rhodamine6 g and guanfacine are calculated from their respective standard curves, and standardized with the cellular protein content determined by a Pierce bicinchoninic acid protein kit.(Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
