Usage

General Description

Oleosides are a group of chemical compounds found in a variety of plants, including olive leaves and other Oleaceae family plants. These compounds are known for their potential therapeutic properties, including anti-inflammatory and antioxidant effects. Oleosides have been studied for their ability to reduce oxidative stress, protect against neurodegenerative diseases, and fight inflammation. They may also have potential as a natural alternative to traditional pharmaceuticals for treating conditions such as cancer, diabetes, and cardiovascular disease. Overall, oleosides are a promising group of compounds with diverse potential health benefits.

New semi-synthetic analogs of oleuropein show improved anticancer activity in?vitro and in?vivo

Oleuropein is a glucosylated seco-iridoid present in olive fruits and leaves. Due to its broad spectrum of biological activities, including anticancer properties, oleuropein has attracted scientific attention for the past 20 years. The promising antiproliferative activity of an olive leaf extract enriched in oleuropein against a series of human cancer cell lines, prompted us to proceed with the semi-synthesis of 51 analogs of oleuropein. Following their initial screening against the estrogen receptor negative breast cancer cell line SKBR3, 7 analogs were shown to display significant cytotoxicity and were further tested against 6 additional solid tumor-derived and leukemic cell lines. The analog with the most promising antitumor activity (24) was selected for more detailed studies. 24 was non-toxic to peripheral blood mononuclear cells derived from healthy blood donors when tested at concentrations close to its half maximal inhibitory concentration. In vivo administration of 24 in melanoma-bearing mice resulted in reducing tumor size in a dose-dependent manner and in inducing anti-melanoma-reactive immune responses. Our results suggest that analog 24, emerging from the initial structure of oleuropein, represents a promising lead structure for further optimization.

Oleuropein site selective hydrolysis by technomimetic nuclear magnetic resonance experiments

Technomimetic NMR experiments were performed in accordance with the lye treatment adopted during table olive industrial procedures for the debittering process causing oleuropein degradation. The site selective hydrolysis of the two ester groups, character

PROCESS FOR THE PRODUCTION OF OLEOCANTHAL, OLEACEIN AND THEIR ANALOGUES

A process for the production of a compound according to Formula (I), such as oleocanthal or oleacein, starting from oleuropein. The process provides the dialdehyde core of oleocanthal, oleacein and their analogues having the required stereochemistry. Furthermore, the process can be used for the production of a large number of structurally diverse products by varying the structure of the alcohol moiety in the esterification step.

Ilicifoliosides A and B, bis-secoiridoid glycosides from Osmanthus Ilicifolius

Two new bis-secoiridoid glycosides, named ilicifoliosides A and B, were isolated from the leaves of Osmanthus ilicifolius. Their structures have been determined by 1D and 2D NMR analysis.
