  SAR of the arylpiperazine moiety of obeline somatostatin sst1 receptor antagonists

  摘要：

  The SAR of over 50 derivatives of octahydrobenzo[g]quinoline (obeline)-type somatostatin sst, receptor antagonist 1 is presented, focusing on the modification of its arylpiperazine moiety. sst(1) affinities in this series cover a range of five orders of magnitude with the best derivatives displaying subnanomolar sst, affinities and > 10,000-fold selectivities over the sst, receptor subtype as well as promising pharmacokinetic properties.

• Decahydroisoquinoline derivatives as novel non-peptidic, potent and subtype-selective somatostatin sst3 receptor antagonists

  Starting from non-peptidic sst(1)-selective somatostatin receptor antagonists, first compounds with mixed sst(1)/sst(3) affinity were identified by directed structural modifications. Systematic optimization of these initial leads afforded novel, enantiomerically pure, highly potent and sst(3)-subtype selective somatostatin antagonists based on a (4S,4aS,8aR)-decahydroisoquinoline-4-carboxylic acid core moiety. These compounds can efficiently be synthesized and show promising PK properties in rodents. (C) 2010 Elsevier Ltd. All rights reserved.
