  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.

• Synthesis of Dihydronaphthalenes via Aryne Diels−Alder Reactions:  Scope and Diastereoselectivity
  作者：Chris Dockendorff、Stefan Sahli、Madeline Olsen、Ludovic Milhau、Mark Lautens

  DOI：10.1021/ja055498p

  日期：2005.11.1

  Novel aryne Diels-Alder reactions with functionalized acyclic dienes are reported. These give useful cis-substituted dihydronaphthalene building blocks in good yield which are not easily accessible via other means, as demonstrated in the synthesis of sertraline. The first asymmetric aryne cycloaddition with an acyclic diene is also reported, giving excellent diastereoselectivities with Oppolzer's sultam

  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

  作为我们研究的延伸，旨在发现一种对组胺和慢反应物质 (SRS) 具有双重活性的新型化合物，我们合成了两种类型的吲哚哌啶衍生物，3 和 4-20。体内抗过敏活性和体外抗 SRS 活性测试表明 (2E, 4E) -5- (3,5 - 二甲氧基 - 4 - 羟基苯基) -N- (2- (4- (1H - indole - 3 ‐Yl) 哌啶 ‐ 1 ‐ yl) 乙基) ‐2,4 - 戊二烯酰胺 (11) 表现出有效的双重活性，分别为 ED50 = 0.89 mg / kg 和 IC50 = 1.43 μM。然而，当在豚鼠中口服给药时，未改变的 11 的血浆浓度非常低。这一结果可以通过快速形成葡萄糖醛酸结合物来解释。

  According to the invention, there are provided novel amide derivatives and 5-lipoxygenase inhibitors containing the same as an effective ingredient. The above-mentioned compounds of the invention have been demonstrated to possess 5-lipoxygenase-inhibiting activities. These compounds can inhibit the production of leucotrienes such as LTC4 and LTD4 which are allergy-inducing factors by inhibiting the activity of 5-lipoxygenase. Accordingly, the amide derivatives can be used as 5-lipoxygenase inhibitors effective for allergic asthma, allergic rhinitis and the like.

  根据本发明，提供了新型酰胺衍生物和以酰胺衍生物为有效成分的 5-脂氧合酶抑制剂。 上述本发明化合物已被证实具有 5-脂氧合酶抑制活性。 这些化合物可以通过抑制 5-脂氧合酶的活性来抑制白三烯（如 LTC4 和 LTD4）的产生，而白三烯是过敏诱因。 因此，酰胺衍生物可用作 5-脂氧合酶抑制剂，对过敏性哮喘、过敏性鼻炎等有效。
