  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.

  高效的Meerwein-Ponndorf-Verley降低了强大的锆-有机硼酸混合溶液

  摘要：

  Meerwein-Ponndorf-Verley（MPV）反应是一种选择性还原羰基的有吸引力的方法，而先进催化剂的设计是这类有趣反应的关键。本文中，我们使用1,4-苯二硼酸（BDB）作为MPV还原的前体，制备了新型有机硼酸锆。制备的Zr-BDB对MPV还原各种生物质衍生的羰基化合物具有优异的催化性能（即，乙酰丙酸酯，醛和酮）。更重要的是，由于硼酸根在氢源中对羟基的活化作用，配体上硼酸根的数目显着影响Zr-有机配体杂化物的催化活性。详细的研究表明，Zr-BDB的优异性能归功于Zr 4+和硼酸盐的协同作用。值得注意的是，这是提高硼酸根基MPV反应中Zr基催化剂活性的第一项工作。

  The oxidation of alcohols to carbonyl compounds using air as the terminal oxidant is highly desirable. As described in previous reports, the abstraction of α-H of the alcohol is the most important step, and it typically requires not only a metal catalyst but also complex ligands, co-catalysts and bases.
