Forskolin 作用机制 工作浓度实验方法

Forskolin (Coleonol) 是一种有效的腺苷酸环化酶 (adenylate cyclase) 激活剂，对于 I 型腺苷酸环化酶，IC50 为 41 nM，EC50 为 0.5 μM。Forskolin 也是一种细胞内 cAMP 形成的诱导剂。Forskolin 诱导多种细胞类型的分化并激活孕烷 X 受体 (PXR) 和 FXR。Forskolin 对心脏产生正性肌力作用，并具有血小板抗凝集和降压作用。Forskolin 也可诱导细胞自噬 (autohagy)。

产品描述：    

Forskolin (Coleonol) is a potent adenylate cyclase activator with an IC50 of 41 nM and an EC50 of 0.5 μM for type I adenylyl cyclase[1]. Forskolin is also an inducer of intracellular cAMP formation[2]. Forskolin induces differentiation of various cell types and activates pregnane X receptor (PXR) and FXR[3]. Forskolin exerts a inotropic effect on the heart, and has platelet antiaggregatory and antihypertensive actions. Forskolin also induces autohagy[4][5].


靶点：IC50 & Target     ：

IC50: 41 nM (Adenylyl cyclase)[1]
EC50: 0.5 μM (Adenylyl cyclase)[1]


体外实验：

Forskolin (Coleonol) is also a potent exosome biogenesis and/or secretion activator in prostate cancer (PC) cells[8].
Forskolin (Fsk) is a naturally occurring diterpene isolated from Coleus forskholii, directly activates adenylyl cyclase (AC) through its catalytic subunit to increase intracellular levels of cyclic adenosine monophosphate (cAMP)[1].
Forskolin (Fsk) affects the proliferation of the human T-cell lines such as Kit 225 and MT-2. Forskolin treatment inhibits the proliferation of both Kit 225 and MT-2 cells in a dose-dependent manner with an IC50 equal to ~5 μM Fsk. Forskolin treatment (10-100 μM) increases cAMPi levels ~5- to 20-fold above basal levels, which reache maximum levels between 50-100 μM Forskolin[6].

体内实验:

The Forskolin (Coleonol)-treated Mrp4-/- mice shows an increased number of Ki67-positive and cleaved caspase 3-positive ECs, a significant decrease in the amount of pericyte coverage, and a reduced number of empty sleeves. In pups exposed to hyperoxia (75% oxygen) from P7 to 12, the Mrp4-/- mice shows a significant increase in the unvascularized retinal area[2].
The average blood glucose in the healthy rat group is 102.12±1.94 mg/dL, 101.25±3.56 for control group and 03±2.08 in forskolin group. The data shows that glucose levels at the end of the study are lower in forskolin group, with a significant difference according to the statistical tests applied (p=0.03)[7].
