Biochem/physiol Actions

NKH 477 is a potent, orally active adenylyl cyclase activator. It is a water soluble derivative of forskolin, and dose dependentyl increases cAMP and blocks potassium-induced contraction concetrations in smooth muscle strips (IC50 = 80 nM). NKH 477 causes relaxation of histamine treated guinea pig smooth muscle (IC50 = 32 nM).
