产品描述

佛司可林(Forskolin,CAS NO.:66575-29-9)是一种来源于印度彩叶植物毛喉鞘蕊花(Coleus forskohlii)的天然生成二萜。通过作用于催化亚基直接激活腺苷酸环化酶(AC),引起细胞内cAMP水平的提高[1-2]。在稳定转染且表达I型腺苷酸环化酶(AC1)的Sf9细胞,Forskolin与膜上的AC1结合(IC50=41nM)并活化其功能(EC50=0.5 μM,评估从ATP生成cAMP的激活实验)[3]。Forskolin以浓度依赖性的方式发挥平滑肌松弛剂和血管扩张剂的功能,同时影响细胞质钙离子水平和收缩成分的钙离子敏感性[4]。Forskolin能够与葡萄糖转运体和某些离子通道相互作用,可用来检测腺苷酸环化酶的表达、调控和G蛋白信号通路[5]。Forskolin用于几种分化方案中以增强神经元分化能力[6-7]。


我司提供两种形式的佛司可林(Forskolin):

一种是溶于DMSO的50mM储存液形式,对应货号是:MZ2301-50UL(~1mg),MZ2301-250UL(~5mg),直接用培养基稀释到所需工作浓度即可。操作简单方便。

一种是冻干粉形式,对应货号是:MZ2301-50MG,MZ2301-100MG。需要先用DMSO或无水乙醇配制成储存液,再用培养基稀释到所需工作浓度使用。


Forskolin通常用在各种类型的完整细胞或组织培养物中来提高cAMP水平,常用工作浓度为10-50μM。具体的最佳工作浓度请参考文献,或根据自身实验体系,培养细胞和组织类型,通过实验进行摸索和优化。

体外研究:

细胞类型(Cell type):Human leukemic cell line MT-2 cells

药物配制(Preparation):Forskolinwas dissolved in DMSO to make stock solution.

实验方法(Assay):MT-2 cells were seeded into 96-well plates at 5 × 104 cells per well. Cells were then pretreated for1 h with 1% DMSO (vehicle) or Fsk at 1, 5, 10, 25, 50, and 100 μM concentrations. The cells were stimulated with IL-2 as above and cultured for an additional 20 h at 37 °C. Control cells were treated with 1% DMSO for 20 h. During the final 4 h of incubation, the cells were pulsed with [3H]thymidine at a concentration of 0.5 μCi/200 μl. Cells were harvested onto fiberglass filters and analyzed using liquid scintillation counting.Fsk treatment inhibited the proliferation of MT-2 cells in a dose-dependent manner with an IC50 equal to∼5 μM Fsk.

体内研究:

动物模型(Animal Model):C57BL/6J mice and Mrp4-knockout mice

药物配制(Preparation):Forskolin was dissolved in dimethyl sulfoxide (DMSO) and then diluted.

注射剂量(Dosages):Forskolin was dissolved in DMSO and injected intraperitoneally into neonatal mice at postnatal days 4 (P4) (1.0 μg/50 μL (0.3 mg/kg))and 5 (P5)(1.5 μg/50 μL (0.5 mg/kg)). Mice injected with DMSO served as the controls. The treated mice were euthanized at P6, and their retinas were isolated for whole-mount immunohistochemistry (IHC)

给药途径(Administration):Intraperitoneally (i.p.) Injection
