Biological Activity for Forskolin

Forskolin, or coleonol, is a cell-permeable, potent, reversible and rapid activator of adenylyl cyclase, an enzyme that converts ATP to cAMP and pyrophosphate (EC50 = 0.5 μM). In combination with 5 other compounds, forskolin enables chemical reprogramming of mouse embryonic fibroblasts to pluripotent stem cells, without genetic factors: Valproic acid, sodium salt (Cat. No. 2815), RepSox (Cat. No. 3742), Tranylcypromine hydrochloride (Cat. No. 3852), CHIR 99021 (Cat. No. 4423) and 3-Deazaneplanocin A hydrochloride (Cat. No. 4703). In combination with IBMX (Cat. No. 2845), forskolin induces neural differentiation of mesenchymal stem cells by downregulating neuron restrictive silencer factor. In a rat model of Huntington's disease-like neurodegeneration, forskolin also exhibits neuroprotective effects. Hypotensive and vasodilatory agent.

Water-soluble analog, NKH 477 (Cat. No. 1603), and Forskolin synthesized to Ancillary Material Grade also available.

For more information about how Forskolin may be used, see our protocol: Transdifferentiating Fibroblasts into Neurons.

Forskolin increases intracellular cAMP levels.
By Niroj Shrestha on 07/08/2019
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: HEK293

HEK293 cells transfected with cAMP FRET sensor, Epac-S(H187) were perfused in normal tyrode solution and excited alternately at 430 nm and fluorescence was captured at 470 and 535 nm. Forskolin (10 µM) was added at 1 min to activate adenylyl cyclase and increase intracellular cAMP, which is detected as an increase in 470/535 fluorescence ratio.
