  在犬第二代幼虫中与哌酰胺有关的芳烷基和芳烯基酰胺的合成和杀线活性。

  摘要：

  合成了与哌啶相关的79个芳烷基和芳烯基酰胺，并研究了它们对犬round虫Toxocara canis的第二级幼虫的杀线虫活性。活性很大程度上取决于烷基链的长度和胺部分的性质，但是几乎不受链中是否存在双键的影响。在一系列同系物中表现出最强活性的烷基链长，对于吡咯烷酰胺为m = 11，对于N-甲基哌嗪酰胺为m = 13。尽管在所测试的同系物中，哌啶（3，4-亚甲基二氧苯基同系物）显示出最强的活性，但是芳环上的甲氧基取代基对该活性没有太大影响。然而，甲氧基向羟基的转化大大降低了活性并缩短了链长，从而提供了最强的活性。计算出的非酚芳基哌啶的log P值在3.5至4.5范围内，而羟苯基哌啶的log P值较小，表明酚和非酚化合物的杀线活性涉及不同的机理。

  N-Acylethanolamine acid amidase (NAAA) is one of the key enzymes involved in the degradation of fatty acid ethanolamides (FAEs), especially for palmitoylethanolamide (PEA). Pharmacological blockage of NAAA restores PEA levels, providing therapeutic benefits in the management of inflammation and pain. In the current work, we showed the structure-activity relationship (SAR) studies for pyrrolidine amide

  N-酰基乙醇胺酸酰胺酶（NAAA）是参与脂肪酸乙醇酰胺（FAE）降解的关键酶之一，尤其是对于棕榈酰乙醇酰胺（PEA）而言。NAAA的药理学阻断作用可恢复PEA水平，从而在炎症和疼痛的治疗中提供治疗益处。在当前的工作中，我们显示了吡咯烷酰胺衍生物作为NAAA抑制剂的结构-活性关系（SAR）研究。检查了吡咯烷酰胺的末端苯基的一系列芳族取代基或取代基。SAR数据表明，较小的亲脂性3-苯基取代基对于最佳效用是优选的。构象柔性的接头增加了吡咯烷酰胺衍生物的抑制能力，但降低了其对脂肪酸酰胺水解酶（FAAH）的选择性。构象上受限的接头没有增强抑制剂对NAAA的效力，但是改善了对FAAH的选择性。开发了几种低微摩尔有效的NAAA抑制剂，其中包括带有刚性4-苯基肉桂酰基的4g。透析和动力学分析表明4g通过竞争和可逆的机制抑制NAAA。此外，4g在脂多糖（LPS）诱导的急性肺损伤（ALI）模型中显示出较高的抗

  Inhibitors of drug metabolism have important implications in pharmaco-toxicology and agriculture. We have reported earlier that piperine, a major alkaloid of black and long peppers inhibits both constitutive and inducible cytochrome P450 (CYP)dependent drug metabolising enzymes. In the present study, an attempt has been made to prepare several novel synthetic analogues so as to relate various modifications in the parent molecule to the inhibition of CYP activities. Two types of mono-oxygenase reactions arylhydrocarbon hydroxylase (AHH) and 7-methoxycoumarin-O-demethylase (MOCD) have been studied. Inhibition studies were investigated in rat microsomal fraction prepared from untreated, 3MC- and PB- treated rat liver in vitro. Modifications were introduced into the piperine molecule: (i) in the phenyl nucleus, (ii) in the side chain and (iii) in the basic moiety. Thus, 38 compounds have been subjected to such studies, and simultaneously an attempt has also been made to arrive at the structure-activity relationship of synthetic analogues. In general, most of the inhibitory potential of the parent molecule is lost with modification in either of the three components of piperine. Saturation of the side chain resulted in significantly enhanced inhibition of CYP while modifications in the phenyl and basic moieties in few analogues offered maximal selectivity in inhibiting either constitutive or inducible CYP activities. Thus Few novel analogues as CYP inactivators have been synthesized which may have important consequences in pharmacokinetics and bioavailability of drugs. (C) 2000 Elsevier Science Ltd.

  piperamides (3,4-methylenedioxyphenyl homologues) showed the strongest activity among the homologues tested, methoxy substituent(s) on the aromatic ring did not have much effect on the activity. However, conversion of the methoxy group to a hydroxy group greatly decreased the activity and shortened the chain length giving the strongest activity. Calculated log P values of non-phenolic aryl-piperamides fell
