Prostacyclin-dependent activation of adenylate cyclase in a neuronal somatic cell hybrid: prostanoid structure-activity relationships
Abstract
1 Prostacyclin activates adenylate cyclase of the NCB-20 neuronal hybrid cell line. 2 There is a guanosine 5'-triphosphate requirement for the activation of adenylate cyclase by 5,6 beta-dihydroprostacyclin (a stable analogue of prostacyclin). 3 Steady-state kinetic analysis of the activation of adenylate cyclase by 5,6 beta-dihydroprostacyclin suggests a simple non-cooperative bimolecular interaction between the ligand and single receptor population. 4 Structure-activity relationships of selected prostanoids elucidated certain functional requirements for activation of adenylate cyclase.
