Non-peptidic compounds containing the octahydro-indolo[4,3-fg]quinoline (ergoline) structural element have been optimized into derivatives with high affinity (pK(d) r sst(1) > 9) and selectivity (> 1000-fold for h sst(1) over h sst(2)-h sst(5)) for the somatostatin sst(1) receptor. In functional assays, these ergolines act as antagonists at human recombinant sst(1) receptors. Pharmacokinetic studies in rodents reveal good oral bioavailability and brain penetration for some of these compounds. (C) 2007 Elsevier Ltd. All rights reserved.
