  Structure–activity relationship of piperine and its synthetic analogues for their inhibitory potentials of rat hepatic microsomal constitutive and inducible cytochrome P450 activities

  摘要：

  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.

  describes a novel supported Weinreb amide resin that facilitates parallel synthesis of aldehydes and ketones on a scale useful for chemical library synthesis. This new resin makes it possible to produce custom aldehydes and ketones from a wide range of carboxylic acids, including N-BOC-amino acids. A variety of commercially unavailable aldehydes are easily synthesized in parallel and obtained in high purity

  本文介绍了一种新型的负载型Weinreb酰胺树脂，该树脂有助于以可用于化学库合成的规模并行合成醛和酮。这种新的树脂可以从多种羧酸（包括N-BOC-氨基酸）生产定制的醛和酮。可以轻松地并行合成各种商业上不可用的醛，并通过简单的过滤后处理以高纯度获得这些醛，从而促进了铅优化库的并行合成，该库通常需要定制醛中间体的合成来发展结构-活性关系。为了证明此方法的实用性，我们基于支持的Horner-Emmons试剂合成了一个小型文库。这是首次证明通过担载的Weinreb酰胺产生的醛可直接用作采用对水分敏感的反应的化学文库合成中的试剂。由于必需的费力的萃取后处理程序，有时这些反应性中间体的不稳定性，因此类似的溶液反应不适合于平行合成。

  compound with dual activities against histamine and slow‐reacting substance (SRS), we synthesized two types of indolylpiperidine derivatives, 3 and 4–20. Testing for in vivo antianaphylactic activity and for in vitro anti‐SRS activity revealed that (2E,4E)‐5‐(3,5‐dimethoxy‐4‐hydroxyphenyl)‐N‐(2‐(4‐(1H‐indol‐3‐yl)piperidin‐1‐yl)ethyl)‐2,4‐pentadienamide (11) exhibited potent dual activities with ED50 = 0
