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).

In kidney collecting duct cells, filamentous actin (F-actin) depolymerization is a critical step in vasopressin-induced trafficking of aquaporin-2 to the apical plasma membrane. However, the molecular components of this response are largely unknown. Using stable isotope-based quantitative protein mass spectrometry

Regulated urine concentration takes place in the renal collecting duct upon arginine vasopressin (AVP) stimulation, where subapical vesicles containing aquaporin-2 (AQP2) are inserted into the apical membrane instantly increasing water reabsorption and urine concentration. The reabsorped water exits via basolateral
