  Structure−Activity Relationship of (1-Aryl-2-piperazinylethyl)piperazines:  Antagonists for the AGRP/Melanocortin Receptor Binding

  摘要：

  Agouti-related protein (AGRP) is an endogenous antagonist of the melanocortin action.(1) In the hypothalamus, melanocortin peptide agonists act as satiety-inducing factors that mediate their action through the melanocortin-4 receptor (MC4R) whereas AGRP is an opposing orexigenic agent. Novel inhibitors of the AGRP/MC4 binding based on (piperazinylethyl)piperazines were prepared, and their structure-activity relationship was established.

  摘要：

  通过将2-氯-4'-氟乙酰苯酮与1-(乙氧羰基)哌嗪反应得到化合物V，然后用硼氢化钠还原为氨基醇VIf。将VIf的盐酸盐与亚硫酰氯处理得到1-[2-氯-2-(4-氟苯基)乙基]-4-(乙氧羰基)哌嗪的盐酸盐（VIg）。粗制的VIg在苯中与二乙胺、吡咯烷、哌啶、吗啉和1-甲基哌嗪进行取代反应，产生氨基氨基甲酸酯VIa-VIe。用浓缩的乙醇钾氢氧化物水解VIa-VIe，得到胺类物质VIIa-VIIe。这些化合物的盐酸盐与多聚甲醛和丙酮苯酮（和对羟基丙酮苯酮，分别）进行Mannich反应，得到标题化合物IIIa-IIIe、IVa,b和IVd,e。只有IIIa和IIId这两种物质在大鼠和豚鼠中显示出与依普拉津酮（I）相当的止咳活性。在较高剂量下，它们会导致小鼠出现中枢抑制、共济失调和上睑下垂，部分物质在大鼠中还表现出肾上腺素拮抗和降压作用。

  had a relatively high affinity for the MC4 receptor. When diphenylmethyl analogues were further examined, compounds 12c and 18 were also found to exhibit a high affinity for the MC4 receptor (IC(50)=46.7 nM and 33.2 nM, respectively). Furthermore, compound 12c was also found to show a high affinity for the serotonin transporter (IC(50)=10.7 nM). Here, we describe the synthesis and biological evaluation
