  Synthesis and Structure–activity relationships of 1-arylmethyl-3-(1-methyl-2-amino)ethyl-5-aryl-6-methyluracils as antagonists of the human GnRH Receptor

  摘要：

  A new class of small molecule GnRH antagonists, the 1-arylmethyl-3-(1-methyl-2-amino)ethyl-5-aryl-6-methyluracils, was designed and a novel stereoselective synthesis for these compounds was developed. The stereochemical integrities of key intermediates (S)-6 and (R)-6 were confirmed by a combination of X-ray crystallography and chiral HPLC determinations. SAR Studies were performed, which allowed the identification of derivatives (R)-9f, (R)-9h and (R)-12 as potent hGnRH antagonists (K-i=20 nM). (C) 2003 Elsevier Ltd. All rights reserved.

  Synthesis and Structure−Activity Relationships of 1-Arylmethyl-5-aryl-6-methyluracils as Potent Gonadotropin-Releasing Hormone Receptor Antagonists

  摘要：

  Based on the SAR from bicyclic gonadotropin-releasing hormone (GnRH) antagonists such as 6-aminomethyl-7-aryl-pyrrolo[1,2-alpha]pyrimid-4-ones (5) and 2-aryl-3-aminomethyl-imidazolo[1,2-alpha]pyrimid-5-ones (6a,b), a series of novel uracil compounds (8) were derived as GnRH antagonists. The synthesis and SAR studies of 6-methyluracils as human GnRH receptor antagonists are discussed herein. Introduction of a small methyl substituent at the beta-position of the N3 side-chain improved the GnRH binding potency by 5-10-fold. Introduction of a methyl group of (R)-configuration at the alpha-carbon of the N-3 side-chain gave a modest improvement in binding affinity over the unsubstituted ethylene analogues. This modification enabled us to make uracil compounds without the labile 2-pyridylethyl motif on the basic nitrogen while still maintained excellent potency against the hGnRH receptor.
