Syntheses of (−)-Oleocanthal, a Natural NSAID Found in Extra Virgin Olive Oil, the (−)-Deacetoxy-Oleuropein Aglycone, and Related Analogues
摘要:
Phenolic compounds extracted from extra virgin olive oil have attracted considerable recent attention. One of the components, (-)-oleocanthal (1), an inhibitor of the COX-1 and COX-2 enzymes, possesses similar potency as the NSAID ibuprofen. In this, a full account, we disclose the first- and now second-generation syntheses of both enantiomers of the oleocanthals, as well as the first synthesis of the closely related (-)-deacetoxy-oleuropein aglycone and a series of related analogues for structure activity studies. To demonstrate the utility of the second-generation synthesis, multigram quantities of (-)-oleocanthal were prepared in 10 steps (14% overall yield) from commercially available D-lyxose.

see text] Effective total syntheses and the assignment of absoluteconfigurations of both the (+)- and (-)-enantiomers of oleocanthal 1 (a.k.a. deacetoxy ligstroside aglycon), the latter derived from extra virgin olive oils and known to be responsible for the back of the throat irritant properties of olive oils, have been achieved. The absolute and relative stereochemistry of the naturally occurring

A series of phenolic compounds with similar inhibitory COX-1 and COX-2 properties as oleocanthal and oleuropein is described here. The phenolic compounds disclosed here were also found to be MAO and LSD-1 inhibitors. Also provided are methods of using these phenolic compounds in various formulations and compositions including food additives, pharmaceuticals, cosmetics, and animal repellants.

A method of treating cancer or a precancer condition in a mammal comprising administering a therapeutically effective amount of a homovanillyl sinapate analog or pharmacologically acceptable salt, solvate, ester, amide, clathrate, stereoisomer, enantiomer, prodrug or analog thereof, or a combination thereof.
The disclosure provides nicotinamide riboside (NR), the reduced form of NR (NRH), nicotinic acid riboside (NAR), the reduced form of NAR (NARH), derivatives thereof, compositions thereof and uses thereof. The NR and NAR derivatives have improved stability and bioavailability compared to NR and NAR. NR, NRH, NAR, NARH, and derivatives thereof can increase cellular NAD
+
levels and enhance mitochondrial and cellular function and cell viability. Therefore, NR, NRH, NAR, NARH, and derivatives thereof, whether alone or in combination with one or more additional therapeutic agents (e.g., a mitochondrial uncoupler or/and a PARP inhibitor), are useful for treating mitochondrial diseases, mitochondria-related diseases and conditions, metabolic disorders, and other disorders and conditions.
