Antagonism of prostaglandin-induced cyclic AMP accumulation in the rat anterior pituitary in vitro by somatostatin analogues

Abstract
The PGE2-induced cyclic AMP accumulation in the rat anterior pituitary in vitro is inhibited by [desamino1]-, [desamino1] [descarboxy14] and [d-Lys4]-somatostatin similarly to somatostatin, while the [descarboxy14]-somatostatin exhibits reduced activity; [d-Lys9]-somatostatin is ineffective at a higher concentration.
