Forskolin is a diterpenoid isolated from Coleus forskohlii, interacts directly with the catalytic subunit of A cyclase (adenylate cyclase), activating the enzyme and raising intracellular levels of cAMP. Forskolin is cell permeable and active in vivo producing positive inotropic, platelet anti-aggregatory and anti-hypertensive effects in vitro. Has also been shown to exhibit smooth muscle relaxant activity, decrease in intraocular pressure and the promotion of hormonal release from the pituitary glands in vitro. Inhibits MAP kinase, induces phosphorylation of CREB, connexin 43, Bad, ATF-1 and PKB. Forskolin is an inhibitor of AChR.

Can Forskolin be filtered through a 0.2 micron filter?

Asked by: ChemSynth123
Thank you for your question. Forskolin (CAS 66575-29-9): sc-3562, is probably only about a nanometer across. If it is truly in solution, and not a suspension of particles (especially >0.2 µm, of course), it should pass through the 0.2 micron filter just fine.
