  Agonist lead identification for the high affinity niacin receptor GPR109a

  摘要：

  A strategy for lead identification of new agonists of GPR109a, starting from known compounds shown to activate the receptor, is described. Early compound triage led to the formulation of a binding hypothesis and eventually to our focus on a series of pyrazole acid derivatives. Further elaboration of these compounds provided a series of 5,5-fused pyrazoles to be used as lead compounds for further optimization. (C) 2007 Elsevier Ltd. All rights reserved.

  A series of 5-alkylpyrazole derivatives was synthesized and evaluated for potent hypolipidemic activity in rats. Many pyrazole derivatives with an alkyl group at the 5 position of the pyrazole ring were found to possess high hypolipidemic activity. Homologation of the alkyl chain led to marked increase in activity, but introduction of other substituents at other sites on the pyrazole ring failed to

  合成了一系列的5-烷基吡唑衍生物，并对其在大鼠中的有效降血脂活性进行了评估。发现许多在吡唑环的5位具有烷基的吡唑衍生物具有高降血脂活性。烷基链的同源性导致活性显着增加，但是在吡唑环上其他位点引入其他取代基未能增强活性。另外，用异恶唑环取代吡唑环导致活性显着降低。在测试的化合物中，5-n-十三烷基吡唑-3-羧酸（5k）表现出最有利的活性谱，并且与氯贝特一样有效。该化合物5k在急性试验（LD50 = 10.0g / kg）中显示出相当低的毒性，因此目前正在接受进一步的药理评估。

  In order to investigate the generality of a chain-elongation reaction observed in the metabolism of fusaric acid (5-butyl-2-pyridinecarboxylic acid) and its derivatives, various heteroaromatic (diazine, 1, 3-azole, and 1, 2-azole) carboxylic acids with a normal alkyl side-chain were synthesized.

  为了研究在fusari酸（5-丁基-2-吡啶酸）及其衍生物代谢中观察到的链延长反应的普遍性，合成了多种具有正常烷基侧链的杂芳香羧酸（嗪类、1,3-噁唑类和1,2-噁唑类）。

  A series of 5-alkyl pyrazole-3-carboxylic acids were prepared and found to act as potent and selective agonists of the human GPCR, GPR109a, the high affinity nicotinic acid receptor. No activity was observed at the highly homologous low affinity niacin receptor, GPR109b. A further series of 4-fluoro-5-alkyl pyrazole-3-carboxylic acids were shown to display similar potency. One example from the series was shown to have improved properties in vivo compared to niacin. (c) 2007 Elsevier Ltd. All rights reserved.
