This review highlights the multiple properties of the birch bark-derived pentacyclic triterpene betulin with special focus on its pharmacological activity in cancer and inflammation. While less well characterized compared to its hydrophilic derivative, betulinic acid, it exhibits potent anticancer
OBJECTIVE
Signal transducer and activator of transcription 3 (STAT3) is an important regulator of cardiac survival pathways. Decreased expression or activity of STAT3 in patients with end-stage heart failure demonstrated a clinical relevance of STAT3 in cardiac diseases. Betulin, a pentacyclic
Mastitis is a postpartum disease in both humans and animals. Staphylococcus aureus (S. aureus) can induce mastitis by infection of the lactiferous ducts. There is no efficacious treatment for S. aureus-induced mastitis. Betulin has been confirmed to have multiple biological activities, including
Betulin is a pharmacologically active triterpenoid found in the bark of the birch tree (Betula sp. L.). Betulin and betulinic acid are structurally related to anti-inflammatory steroids, but little is known about their potential anti-inflammatory properties. In the present study, the inflammatory
The present study was intended to examine the analgesic effect of the 70% methanol extract of Torenia concolor Lindley var. formosana Yamazaki (TC(MeOH)) and betulin using models of acetic acid-induced writhing response and formalin test. In addition, we investigated the anti-inflammatory effect of
Asthma is a chronic, serious allergic inflammatory disease in the airway. The inflammation in the airway is induced by the allergic T-helper 2 cells (Th2 cells), which leads to unfettered production of inflammatory cytokines. The accretion of inflammatory cells in the airway also speeds up the
BACKGROUND
Pentacyclic triterpenes, mainly betulin and betulinic acid, are valuable anticancer agents found in the bark of birch tree. This study evaluates birch bark extracts for the active principles composition.
RESULTS
New improved extraction methods were applied on the bark of Betula pendula in
Continued oxidative stress can lead to chronic inflammation, which in turn could mediate most chronic diseases including cancer. Nuclear factor erythroid 2-related factor (Nrf2), a critical transcriptional activator for antioxidative responses, has envolved to be an attractive drug target for the
The aim of this study is to study the effect of betulin (BE) on myocardial injury in diabetic mice. Insulin-related indexes and inflammation-related cytokines are detected by commercial kits. The mechanism of BE on diabetic myocardial injury was studied by modern molecular biology techniques. BE
Biotransformation of lupane-type triterpenoid betulin was carried out with Mucor subtilissimus CGMCC 3.2456. Yielded nine previously undescribed hydroxylated compounds. M. subtilissimus biotransformation provided C-7, C-11, C-15 and C-24 hydroxylated compounds along with C-7 oxidized and C-28
OBJECTIVE
The present study was carried out to investigate analgesic and anti-inflammatory activities of Cassia siamea Lam stem bark extracts. We have also determined the cytotoxicity of each extract.
METHODS
C. siamea, a widespread medicinal plant traditionally used in sub-Saharan Africa, was
Background: Prevention and treatment of chronic inflammatory diseases require effective and low-toxic medicines. Molecular hybridization is an effective strategy to enhance the biological activity of new compounds. Triterpenoid scaffolds
Ethanol consumption leads to many kinds of liver injury and suppresses innate immunity, but the molecular mechanisms have not been fully delineated. The present study was conducted to determine whether betulinic acid (BA) or betulin (BT) would ameliorate acute ethanol-induced fatty liver in mice,
Betulin, a pentacyclic triterpene, possesses antioxidant, anti-inflammatory and hepatoprotective properties. The aim of this study was to evaluate the impact of liver mitochondria in hepatoprotection of betulin using a rat model of alcoholic steatohepatitis induced by ethanol administration (4 g/kg,
This study compared the antinociceptive and anti-inflammatory effects of various parts of Broussonetia papyrifera (L.) L'Herit. ex Vent. (BP, Moraceae) by chemical-induced pain and inflammation in rodents. All BP parts (1 and 2 g/kg, p.o.) effectively inhibited writhing responses induced by 1%
