産品描述

佛司可林(Forskolin,CAS NO.:66575-29-9)是一(yī)種來源于印度彩葉植物(wù)毛喉鞘蕊花(Coleus forskohlii)的天然生(shēng)成二萜。通(tōng)過作用于催化亞基直接激活腺苷酸環化酶(AC),引起細胞内cAMP水(shuǐ)平的提高(gāo)[1-2]。在穩定轉染且表達I型腺苷酸環化酶(AC1)的Sf9細胞,Forskolin與膜上(shàng)的AC1結合(IC50=41nM)并活化其功能(néng)(EC50=0.5 μM,評估從(cóng)ATP生(shēng)成cAMP的激活實驗)[3]。Forskolin以濃度依賴性的方式發揮平滑肌松弛劑和血管擴張劑的功能(néng),同時影響細胞質鈣離子水(shuǐ)平和收縮成分的鈣離子敏感性[4]。Forskolin能(néng)夠與葡萄糖轉運體和某些離子通(tōng)道相(xiàng)互作用,可用來檢測腺苷酸環化酶的表達、調控和G蛋白(bái)信号通(tōng)路(lù)[5]。Forskolin用于幾種分化方案中以增強神經元分化能(néng)力[6-7]。


我司提供兩種形式的佛司可林(Forskolin):

一(yī)種是溶于DMSO的50mM儲存液形式,對應貨号是:MZ2301-50UL(~1mg),MZ2301-250UL(~5mg),直接用培養基稀釋到(dào)所需工(gōng)作濃度即可。操作簡單方便。

一(yī)種是凍幹粉形式,對應貨号是:MZ2301-50MG,MZ2301-100MG。需要先用DMSO或無水(shuǐ)乙醇配制成儲存液,再用培養基稀釋到(dào)所需工(gōng)作濃度使用。


Forskolin通(tōng)常用在各種類型的完整細胞或組織培養物(wù)中來提高(gāo)cAMP水(shuǐ)平,常用工(gōng)作濃度為(wèi)10-50μM。具體的最佳工(gōng)作濃度請參考文獻,或根據自(zì)身實驗體系,培養細胞和組織類型,通(tōng)過實驗進行摸索和優化。

體外研究:

細胞類型(Cell type):Human leukemic cell line MT-2 cells

藥物(wù)配制(Preparation):Forskolinwas dissolved in DMSO to make stock solution.

實驗方法(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.

體内研究:

動物(wù)模型(Animal Model):C57BL/6J mice and Mrp4-knockout mice

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

注射劑量(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)

給藥途徑(Administration):Intraperitoneally (i.p.) Injection
