In this work, 40 analogs with a natural maslinic acid core (from Olea europaea L.) and various aromatic azides were synthesized. A regiospecific, facile and practical synthesis of 1,5-triazolyl derivatives by Ru(II)-catalyzed azide-alkyne cycloaddition (RuAAC), and mono-, bis- and tri-1,4-triazolyl
Ischemia/reperfusion (I/R)-induced inflammation is associated with enhanced leukocyte rolling, adhesion and transmigration within the microcirculation. These steps are mediated by hypoxia-triggered signaling pathways, which upregulate adhesion molecule expression on endothelial cells and pericytes.
Maslinic acid (MA), a natural compound of the triterpenoid group derived from olive, prevents the generation of pro-inflammatory cytokines and oxidative stress. In human umbilical vein endothelial cells (HUVECs) treated with lipopolysaccharide (LPS), we characterized the effects of MA on the
Osteoarthritis (OA) is a degenerative joint disease characterized by destruction of articular cartilage. The inflammatory response is the most important factor affecting the disease process. As interleukin-1β (IL-1β) stimulates several key mediators in the inflammatory response, it plays a major
Secretory phospholipase A2-IIA (sPLA2-IIA) is one of the key enzymes causing lipoprotein modification and vascular inflammation. Maslinic acid is a pentacyclic triterpene which has potential cardioprotective and anti-inflammatory properties. Recent research showed that maslinic acid interacts with
Maslinic acid is a pentacyclic triterpene with a plethora of biological activities, including anti-inflammatory, antioxidant, antimicrobial, cardioprotective, and antitumor effects. New derivatives with improved properties and broad-spectrum activity can be obtained following structural changes of
Maslinic acid (2-α, 3-β-dihydroxyolean-12-en-28-oic acid) is a natural triterpenoid compound from Olea europaea. This compound prevents oxidative stress and pro-inflammatory cytokine generation in vitro. This study was planned to investigate the anti-inflammatory effects of maslinic acid in central
METHODS
Consumption of olives (Olea europaea L.), including table olives and oil, is associated with low incidence of inflammation-related diseases. In this study, the effects of maslinic acid (MA), the main constituent of olive pomace, on the expression of genes and proteins involved in
Chronic inflammation drives the development of various pathological diseases such as rheumatoid arthritis, atherosclerosis, multiple sclerosis, and cancer. The arachidonic acid pathway represents one of the major mechanisms for inflammation. Prostaglandins (PGs) are lipid products generated from
METHODS
A previous study demonstrated that intake of olive pomace extract containing maslinic acid (MA), a triterpene, effectively prevents and alleviates arthritis in animals and humans. Here, the molecular mechanisms involved in the anti-arthritis effect of MA have been elucidated by determining
Seizure is a neurological disorder including hippocampal oxidative and inflammatory stress, and glutamate toxicity. Thus, any agent(s) that mitigate(s) these events in hippocampus might attenuate seizure severity. The effects of asiatic acid (AA) or maslinic acid (MA) pre-administration at 20 or
Traditional medicine and diet has served mankind through the ages for prevention and treatment of most chronic diseases. Mounting evidence suggests that chronic inflammation mediates most chronic diseases, including cancer. More than other transcription factors, nuclear factor-kappaB (NF-κB) and
Impaired endothelial functions are closely associated with many chronic vascular-related diseases. Maslinic acid (MA), a natural pentacyclic triterpene compound, has received more and more attentions in recent years due to a variety of bioactivities. In the present study, we investigated the effect
The chemical study of aerial parts of Lampaya hieronymi Schum. ex Moldenke yielded oleanolic acid, epi-oleanolic acid, epi-maslinic acid, 4'7-dimethoxyapigenin, p-hydroxyacetophenone, and p-hydroxyacetophenone-beta-glucoside. In searching for natural products as potential anti-inflammatory agents,
Consumption of olives (Olea europaea L.) is associated with a low incidence of inflammation-related diseases. Olive fruit is rich in bioactive pentacyclic triterpenoids, mainly maslinic acid. This study, a randomized, double-blind, and placebo-controlled trial, examined the effects of an orally
