Biological Activity for NKH 477

NKH 477 is a water-soluble analog of forskolin (Cat. No. 1099) that is a potent activator of adenylyl cyclase; shows some selectivity for cardiac (type V) adenylyl cyclase. Stimulates bronchodilation (EC50 = 32.6 nM) and is an orally active potent positive chronotrope and hypotensive agent in vivo.
