orally active GnRH antagonists based on a 4-piperazinylbenzimidazole template, we sought to investigate the properties of heterocyclic isosteres of the benzimidazole template. We report here the synthesis and biological activity of eight novel scaffolds, including imidazopyridines, benzothiazoles and benzoxazoles. The 2-(4-tert-butylphenyl)-8-(piperazin-1-yl)imidazo[1,2-a]pyridine ring system was shown
促性腺激素释放激素(GnRH)受体的拮抗作用已在生殖组织疾病(例如子宫内膜异位症和前列腺癌)中产生了积极的临床结果。继最近发现基于4-哌嗪基苯并咪唑模板的口服活性GnRH拮抗剂后,我们试图研究苯并咪唑模板的杂环等位体的性质。我们在这里报告了八个新型支架的合成和生物学活性,包括咪唑并吡啶,苯并噻唑和苯并恶唑。2-(4-叔丁基苯基)-8-(哌嗪-1-基)咪唑[1,2- a已显示]吡啶环系统对人和大鼠GnRH受体具有纳摩尔结合力,并在体外具有功能拮抗作用。报告了该系列中其他结构-活性关系以及与基于苯并咪唑的铅分子的药代动力学比较。
