Forskolin is a cell-permeable activator of adenylyl cyclase [1].

Adenylate cyclase is an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to 3',5'-cyclic AMP (cAMP) and pyrophosphate.

Forskolin is a cell-permeable activator of adenylyl cyclase. In rat cerebral cortical membranes, forskolin reversibly and rapidly activated adenylate cyclase with EC50 value of 5-10 μM. GTP and GDP increased the responses to forskolin. In rat cerebral cortical slices, forskolin rapidly increased cAMP by 35-fold with IC50 values of 25 μM [1]. Forskolin inhibited the inactivation of adenylate cyclases induced by N-ethylmaleimide with Kd values of 7.6 and 6.3 μM for the platelet and brain adenylate cyclases, respectively. Also, forskolin protected adenylate cyclases against thermal inactivation. Forskolin activated the platelet adenylate cyclase with IC50 and Kd values of 3-10 μM and 9-11 μM, respectively [2]. In pig epidermal cells, forskolin activated epidermal adenylate cyclase with Ka value of 2-3×10-5 M and induced cAMP accumulations, which then inhibited mitotic in a dose-dependent way [3].

Shipping Condition	Small Molecules with Blue Ice, Modified Nucleotides with Dry Ice.
General tips	We do not recommend long-term storage for the solution, please use it up soon.

Cell experiment [1, 2]:
Cell lines	Human mesenchymal stem cells
Preparation method	The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.
Reacting condition	0.075-0.2 mM for 4 days or 7 days; or 10 μM
Applications	Forskolin concentration-dependently decreased human mesenchymal stem cells proliferation after 4 days. Moreover, Forskolin increased alkaline phosphatase (ALP) expression of human mesenchymal stem cells in a dose-dependent manner. Additionally, Forskolin (10 μM) significantly stimulated both vasopressin and oxytocin release from the rat hypothalamo-neurohypophysial (H-NH) system.
Animal experiment [1]:
Animal models	Particles were implanted in subcutaneous pockets of nude male mice model
Dosage form	0.10 or 0.15mM Forskolin
Applications	Treatment with 0.10 mM Forskolin enhanced bone formation by human mesenchymal stromal cells in vivo.
Other notes	Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
