WebAdenylyl cyclase (AC) isoforms 1 to 9 are differentially expressed in tissues and constitute an interesting drug target. ACs 1 to 8 are activated by the diterpene, forskolin (FS). It is unfortunate that there is a paucity of AC isoform-selective activators. WebSomatostatin was equally effective at inhibiting basal adenylyl cyclase activity in the presence of GTP, forskolin-stimulated activity, and hormone-stimulated activity. G protein /3r was more effective at inhibiting basal activity than was somatostatin, and these effects were partially additive.

"WebDownload high quality TIFF image. Adenylyl cyclase is a signal amplifier. It acts at the center of the signaling cascade that transduces binding of hormones into cellular responses. When hormones such as adrenaline or glucagon bind to G-protein coupled receptors, they activate G-proteins, which in turn activate adenylyl cyclase. " - Forskolin adenylyl cyclase activation
