Description:
Nonpeptide agonists of each of the five somatostatin receptors were identified in combinatorial libraries constructed on the basis of molecular modeling of known peptide agonists. In vitro experiments using these selective compounds demonstrated the role of the somatostatin subtype-2 receptor in inhibition of glucagon release from mouse pancreatic alpha cells and the somatostatin subtype-5 receptor as a mediator of insulin secretion from pancreatic beta cells. Both receptors regulated growth hormone release from the rat anterior pituitary gland. The availability of high-affinity, subtype-selective agonists for each of the somatostatin receptors provides a direct approach to defining their physiological functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rohrer, S P -- Birzin, E T -- Mosley, R T -- Berk, S C -- Hutchins, S M -- Shen, D M -- Xiong, Y -- Hayes, E C -- Parmar, R M -- Foor, F -- Mitra, S W -- Degrado, S J -- Shu, M -- Klopp, J M -- Cai, S J -- Blake, A -- Chan, W W -- Pasternak, A -- Yang, L -- Patchett, A A -- Smith, R G -- Chapman, K T -- Schaeffer, J M -- New York, N.Y. -- Science. 1998 Oct 23;282(5389):737-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biochemistry and Physiology, Merck Research Laboratories, Post Office Box 2000, Rahway, NJ 07065, USA. susanvrohrer@merck.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9784130" target="_blank"〉PubMed〈/a〉
