Notes: Guanosine-5'-O-(2-thiodiphosphate) is a non-hydrolyzable derivative of GDP (Item No. 31704) and an inhibitor of adenylyl cyclase (AC; Ki = 600 nM).{64906} It is also a partial activator of AC when GTP is absent in rat cerebral cortex membranes (EC50 = 400 nM).{64907} Guanosine-5'-O-(2-thiodiphosphate) (1 µM) prevents norepinephrine-induced nitric oxide (NO) release in cardiac ventricular myocytes.{64905} It reduces female opossum urine-induced firing frequency of olfactory mitral/tufted neuronal cells in male opossums when administered at a concentration of 100 µM.{64908}
