Optically active 3-hetero analogues of isocarbacyclin (34a, 38, 39, 40 and 42) as well as ω-chain analogues have been synthesized from the bicyclic alcohol (1). Compound 34d had more potent anti-platelet aggregating activity than prostacyclin in human platelet-rich plasma.

Vasopressin 1b (V1b) antagonists have been postulated as possible treatments for depression and anxiety. A novel series of potent and selective V1b antagonists has been identified starting from an in-house screen hit. The incorporation of a sulfonamide linker between a tetrahydroisoquinoline core and amino piperidine lead to the identification of a V1b antagonist with similar affinity for human and rat receptors. Further optimization of the right hand portion afforded potent V1b antagonists that possessed moderate to high selectivity over other receptors. (C) 2009 Elsevier Ltd. All rights reserved.
