  Dihydropyridine Neuropeptide Y Y1 Receptor Antagonists

  摘要：

  Dihydropyridine 5a was found to be an inhibitor of neuropeptide Y-1 binding in a high throughput I-125-PYY screening assay. Structure-activity studies around certain portions of the dihydropyridine chemotype identified BMS-193885 (6e) as a potent and selective Y-1 receptor antagonist. In a forskolin-stimulated c-AMP production assay using CHO cells expressing the human Y-1 receptor, 6e demonstrated full functional antagonism (K-b = 4.5 nM). Compound 6e inhibited NPY-induced feeding in satiated rats when dosed at 3.0 and 10.0 mg/kg (ip), and also decreased spontaneous overnight food consumption in rats at doses of 10 and 20 mg/kg (ip).

  合成了一系列的[（苯基哌嗪基）烷基]-异吲哚-1,3-二酮衍生物，用作多巴胺能受体的探针。在该系列中，化合物6a对D4和D3受体的亲和力最高，Ki值在低纳摩尔范围内，D2 / D4-和D2 / D3-选择性指数分别为72和20。采用最优化回合，得到Ki（D4）值为0.62 nM的D4选择性配体噻吩-2-羧酰胺9a，其丁基类似物10a的Ki（D4）和Ki（D3）值为0.03和0.26 nM。对接实验揭示了独特的D4残基Arg186在操纵配体D4亚型受体选择性中的重要性。

  Novel arylpiperazines were identified as alpha(1)-adrenoceptor(BR) subtype-selective antagonists by functional in vitro screening. 3-[4-(ortho-Substituted phenyl)piperazin-1-yl]propylamines were derivatized with N,N-dimethyl anthranilamides, nicotinamides,;as well as carboxamides of quinoline, I,8-naphthyridine, pyrazolo[3,4-b]pyridine, isoxazolo[3,4-b]pyridine, imidazo[4,5-b]pyridine, and pyrazolo[1,5-a]pyrimidines. Strips of rabbit bladder neck were employed as a predictive assay for antagonism in the human lower tract. Rings of rat aorta;a were used as a ''negative screen'' for the test antagonists. Binding to alpha(1)-ARs was relatively sensitive to size and electronic features of the arylpiperazine portion of the antagonists and permissive to these features on the heteroaryl carboxamide side. These structure-affinity findings were exploited to produce nicotinamides (e.g, 13ii and 25x) and pyrazolo[3,4-b]pyridines (e.g. 37f and 37y) ligands with nanomolar affinity at the alpha(1)-AR subtype prevalent in the human lower urinary tract (pA(2) values: 8.8, 10.7, 9.3, and 9.9, respectively) and displaying 2-3 orders of magnitude selectivity over the alpha(1D)-AR.
