Forskolin在各种各样细胞类型中，是一种普遍存在的真核细胞腺苷酸环化酶（AC）激活剂，在细胞生理学研究中，通常用来提高cAMP水平。

Forskolin可以使膜，细胞或组织制备液中cAMP含量上升。Forskolin 不仅可以活化AC 而且可以与某些其它蛋白相互作用，包括葡萄糖转运蛋白和离子通道。Forskolin在不与细胞表面受体相互作用前提下刺激腺苷酸环化酶活性。在脂肪细胞中Forskolin's促进 cAMP产生进而可以抑制嗜碱性粒细胞和肥大细胞脱颗粒作用以及组胺释放，降低血压、眼内压，抑制血小板聚集，促进血管舒张，支气管扩张和甲状腺激素分泌，刺激脂肪分解。Forskolin抑制血小板活化因子 (PAF)的结合, 这种抑制不依赖于cAMP形成可能是 Forskolin's直接作用于 PAF或者通过干扰PAF与它的受体结合实现的。Forskolin似乎对多种膜转运蛋白也有效果并且可以抑制脂肪细胞，红细胞，血小板，和其他细胞中的葡萄糖运输。Forskolin也被用于治疗青光眼。

Adenylyl cyclase (AC)

Forskolin increases cAMP levels in preparations of membranes, cells, or tissues. Forskolin not only activates AC but also interacts with certain other proteins, including glucose transporters and ion channels. Forskolin is able to promote activation of nine different transmembrane iso-forms of AC, albeit with somewhat less efficacy for AC9, which could be used to provides a means to identify and quantify high-affinity binding sites, i.e., G-proteins (Gs)–AC complexes. Activation of s by GPCRs contributes to Forskolin-stimulated cAMP generation in cells because of s-Forskolin potentiation of AC activity. Forskolin stimulates adenylate cyclase activity without interacting with cell surface receptors. Forskolin's potentiation of cAMP in turn inhibits basophil and mast cell degranulation and histamine release, lowers blood pressure and intraocular pressure, inhibits platelet aggregation, promotes vasodilation, bronchodilation, and thyroid hormone secretion, and stimulates lipolysis in fat cells. Forskolin inhibits the binding of platelet-activating factor (PAF), independently of cAMP formation, which may be a result of Forskolin's direct effect on PAF or via interference with PAF binding to receptor sites. Forskolin also appears to have an effect on several membrane transport proteins, and inhibits glucose transport in erythrocytes, adipocytes, platelets, and other cells. Forskolin is used to treat with glaucoma.

The Forskolin (Fsk)-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 P12, the Mrp4-/- mice shows a significant increase in the unvascularized retinal area. The average blood glucose in the healthy rat group is 102.12±1.94 mg/dL, 101.25±3.56 for control group and 103±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).
