  Metabolism of Curcuminoids in Tissue Slices and Subcellular Fractions from Rat Liver

  摘要：

  Curcumin and its natural congeners are of current interest because of their putative anti-inflammatory and anticarcinogenic activities, but knowledge about their metabolic fate is scant. In the present study conducted with precision-cut liver slices from male and female Sprague-Dawley rats, five reductive but no oxidative metabolites of curcumin and its demethoxy and bis-demethoxy analogues were observed and identified by HPLC and GC-MS analysis, mostly by comparison with authentic reference compounds. The major reductive metabolites were the hexahydrocurcuminoids in both male and female rat liver slices, whereas male rats formed more octahydro than tetrahydro metabolites and female rats more tetrahydro- than octahydrocurcuminoids. Tetrahydro, hexahydro, and octahydro metabolites were predominantly present as glucuronides, but a significant proportion of sulfate conjugates was also observed. The lack of formation of oxidative metabolites of curcumin and the ready generation of reductive metabolites were confirmed using rat liver microsomes and cytosol, respectively. Results of enzymatic hydrolysis studies conducted under various conditions revealed that curcumin and demethoxycurcumin are chemically less stable than bis-demethoxycurcumin, whereas the reductive metabolites of all three curcuminoids are stable compounds. This is the first report on the metabolism of demethoxycurcumin and bis-demethoxycurcumin. In view of the chemical instability of the parent curcuminoids, it is proposed to use their major phase I metabolites, that is, the stable hexahydro products, as biomarkers for exposure in clinical studies.

  The chemically modified analogs, the demethylated analogs 4–6, the tetrahydro analogs 7–9 and the hexahydro analogs 10–12, of curcumin (1), demethoxycurcumin (2) and bisdemethoxycurcumin (3) were evaluated for their inhibitory activity on lipopolysaccharide activated nitric oxide (NO) production in HAPI microglial cells. Di-O-demethylcurcumin (5) and O-demethyldemethoxycurcumin (6) are the two most

  对姜黄素 ( 1 )、脱甲氧基姜黄素( 2 ) 和双脱甲氧基姜黄素 ( 3 )的化学修饰类似物、去甲基化类似物4 – 6、四氢类似物7 – 9和六氢类似物10 – 12对脂多糖活化的抑制活性进行了评估HAPI 小胶质细胞中一氧化氮 (NO) 的产生。Di- O-去甲基姜黄素 ( 5 ) 和O-去甲基去甲氧基姜黄素 ( 6 ) 是抑制 NO 生成的两种最有效的化合物。类似物5和6分别比母体姜黄素1和2 的活性高两倍或几乎两倍。此外，这两种化合物抑制了诱导型 NO 合酶的 mRNA 表达水平。类似物5和6的强大神经保护活性提供了潜在的替代化合物，可作为与活化小胶质细胞相关的神经系统疾病的治疗剂进行开发。

  The natural curcuminoids curcumin (1), demethoxycurcumin (2) and bisdemethoxycurcumin (3) have been chemically modified to give 46 analogs and 8 pairs of 1: 1 mixture of curcuminoid analogs and these parent curcuminoids and their analogs were assessed against protozoa of the Tryponosoma and Leishmania species. The parent curcuminoids exhibited low antitrypanosomal activity (EC50 for our drug-sensitive Trypanosoma brucei brucei line (WT) of compounds 1, 2 and 3 are 2.5, 4.6 and 7.7 mu M, respectively). Among 43 curcuminoid analogs and 8 pairs of 1: 1 mixture of curcuminoid analogs tested, 8 pure analogs and 5 isomeric mixtures of analogs exhibited high antitrypanosomal activity in sub-micromolar order of magnitude. Among these highly active analogs, 1,7-bis(4-hydroxy-3-methoxy-phenyl)hept-4-en-3-one (40) was the most active compound, with an EC50 value of 0.053 +/- 0.007 mu M; it was about 2-fold more active than the standard veterinary drug diminazene aceturate (EC50 0.12 +/- 0.01 mu M). Using a previously characterized diminazene-resistant T. b, brucei (TbAT1-KO) and a derived multi-drug resistant line (B48), no cross-resistance of curcuminoids was observed to the diamidine and melaminophenyl arsenical drugs that are the current treatments. Indeed, curcuminoids carrying a conjugated keto (enone) motif, including 40, were significantly more active against 7: b. brucei B48. This enone motif was found to contribute to particularly high trypanocidal activity against all Trypanosoma species and strains tested. The parent curcuminoids showed low antileishmanial activity (EC50 values of compounds 1 and 2 for Leishmania mexicana amastigotes are 16 +/- 3 and 37 +/- 6 mu M. respectively) while the control drug, pentamidine, displayed an EC50 of 16 +/- 2 mu M. Among the active curcuminoid analogs, four Compounds exhibited EC50 values of less than 5 mu M against Leishmania major promastigotes and four against L mexicana amastigotes. No significant difference in sensitivity to curcuminoids between L. major promastigotes and L. mexicana amastigotes was observed. The parent curcuminoids and most of their analogs were also tested for their toxicity against human embryonic kidney (HEK) cells. All the curcuminoids exhibited lower toxicity to HEK cells than to T b. brucei bloodstream forms and only one of the tested compounds showed significantly higher activity against HEK cells than curcumin (1). The selectivity index for T b. brucei ranged from 3-fold to 1500-fold. The selectivity index for the most active analog, the enone 40, was 453-fold. (C) 2009 Elsevier Masson SAS. All rights reserved.
