  Orally bioavailable, indole-based nonpeptide GnRH receptor antagonists with high potency and functional activity

  摘要：

  Stereospecific introduction of a methyl group to the indole-3-side chain enhanced activity in our tryptamine-derived series of GnRH receptor antagonists. Further improvements were achieved by variation of the bicyclic amino moiety of the tertiary amide and by adjustment of the tether length to a pyridine or pyridone terminus. These modifications culminated in analogue 24, which had oral activity in a rat model and acceptable oral bioavailability and half-life in dogs and monkeys. (C) 2001 Elsevier Science Ltd.

  Synthesis of chiral β-methyl tryptamine-derived GnRH antagonists

  摘要：

  The stereospecific formation of 2-aryl-beta -methyl tryptamine derivatives 15 and 16 from chiral 4-chloro-1-(3,5-dimethylphenyl)-3-methylbutanones is described. These intermediates were further manipulated into the GnRH antagonists Ib and Ic in five steps. (C) 2001 Elsevier Science Ltd. All rights reserved.
