  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.

  摘要：

  合成了五种（2,2-二甲基苯并吡喃-6-基）链烷酸，并测试了其抗胶凝活性。可以预见，这些试剂可以通过疏水键结合到血红蛋白S的“供体-受体”区域的非极性位点上。一些（2，2-二甲基苯并吡喃-6-基）链烷酸在侧链上具有1-4个碳原子。链残基被设计成在受体位点相互作用，被合成，并且被发现是中等有效的抗胶凝剂。根据弱结合亲和力或对活性和非活性位点的多重结合，可以合理地观察到两种酸在低浓度下的弱活性。这些化合物对改变变构平衡的影响很小或可忽略不计。（2，

  In an effort to develop potent anti-inflammatory agents, a series of novel chroman derivatives including acyclic amidochromans, chromanyl esters and chromanyl acrylates have been designed, synthesized and fully characterized. These chroman analogues were screened for their anti-inflammatory activities through inhibition of the TNF-α-induced ICAM-1 expression on human endothelial cells. A structure–activity

  We have developed a new class of diarylalkyl amides as novel TRPV1 antagonists. They exhibited potent Ca-45(2+) uptake inhibitions in rat DRG neuron. In particular, the amide 59 was identified as a potent antagonist with IC50 of 57 nM. The synthesis and structure-activity relationship of the diarylalkyl amides are also described.
