  Identification of Centrolobol as the Platyphylloside Metabolite Responsible for the Observed Effect on in Vitro Digestibility of Hay

  摘要：

  Syntheses of the metabolites from platyphylloside, a phenol causing digestibility inhibition in rumen fluid, have been performed to identify the active metabolite. 1,7-Bis(4'-hydroxyphenyl)-3-heptanone (3-platyphyllone), racemic, and the two enantiomers of 1,7-bis(4'-hydroxyphenyl)-3-heptanol (centrolobol) and 1,7-bis(4-hydroxyphenyl)heptane (platyphyllane) were synthesized and tested regarding digestibility inhibition in vitro in cow rumen fluid. All compounds tested induced a decreased digestion. Centrolobol was found to be the metabolite causing the observed effect, and (R)-centrolobol was found to be the enantiomer formed in the rumen liquor in vitro.

The arene diazonium salts are isolated from the reaction mixture by simple filtration. Two complementary protocols are presented, and the utility of the reaction is exemplified for a synthesis of the diarylheptanoid

• Total synthesis of acerogenins E, G and K, and centrolobol
  作者：Tetsuhiro Ogura、Toyonobu Usuki

  日期：2013.4

  The first total synthesis of the diaiylheptanoid acerogenins E and K, isolated from Acer nikoense MAXIM., is described. Formation of the 13-membered m,m-cyclophane skeleton was successfully achieved on the basis of a domino process involving a Miyaura arylborylation intramolecular Suzuki reaction. The cyclization precursor was prepared via a Wittig reaction and Claisen Schmidt condensation, which proceeded in moderate yields. The total synthesis of acerogenin G and centrolobol was also achieved from a common synthetic intermediate. (C) 2013 Elsevier Ltd. All rights reserved.
• Platyphylloside: Metabolism and digestibility reductionin vitro
  作者：Kerstin Sunnerheim-Sjöberg、Per-Göran Knutsson

  日期：1995.9

  The metabolism of platyphylloside [(5S)-5-hydroxy-1,7-bis-(4-hydroxyphenyl)-3-heptanone-5-O-beta-D-glucopyranoside]-known to reduce digestibility-was studied in vitro in sheep rumen liquor. Platyphylloside is hydrolyzed to 5-hydroxy-3-platyphyllone [(5S)-5-hydroxy-1,7-bis-(4-hydroxyphenyl)-3-heptanone], which is reduced to centrolobol [1,7-bis-(4-hydroxyphenyl)-3-heptanol], via 3-platyphyllone [7-bis-(4-hydroxyphenyl)-3-heptanone]. The digestibility-reducing effect was shown to be correlated with the concentration of centrolobol.
• Synthesis of Natural and Non-natural Curcuminoids and Their Neuroprotective Activity against Glutamate-Induced Oxidative Stress in HT-22 Cells

  A strategy for the synthesis of natural and non-natural 5-deoxy-6,7-dihydrocurcuminoids (diarylheptanoids) was developed for the preparation of 14 compounds with varying aromatic substituent patterns and a different functionality in the aliphatic seven-carbon chain. The in vitro protective activity against glutamate-induced neuronal cell death was examined in the murine hippocampal cell line HT-22 to find structural motifs responsible for neuroprotective effects in vitro. Among the tested compounds the ferulic acid-like unit, present in the structures of (E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hept-1-en-3-one (5) and (E)-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hept-1-en-3-one (7), appeared to be an important feature for protection against glutamate-induced neurotoxicity. Both compounds demonstrated significant neuroprotective activity in a concentration range between 1 and 25 μM without showing toxic effects in a cytotoxicity assay with HT-22 cells. Furthermore, (E)-1,7-bis(3,4-dihydroxyphenyl)hept-1-en-3-one (9), exhibiting a caffeic acid-like structural motif, displayed a neuroprotective activity at a nontoxic concentration of 25 μM. In contrast, (1E,6E)-1,7-bis(3,4-dihydroxyphenyl)hepta-1,6-diene-3,5-dione (4, di-O-demethylcurcumin) showed mainly cytotoxic effects. A corresponding single-ring analogue that contains the ferulic acid-like unit as an enone was not active.
