BACKGROUND
Diosbulbin B (DB) is the main constituent of furano-norditerpenes in Dioscorea bulbifera Linn., which is widely distributed in China and was usually used as a remedy for sore throat, struma and tumor. Owing to its potential antitumor activity, DB has been considered as a promising
Dioscorea bulbifera L. (DB) is a traditional Chinese herb used in thyroid disease and cancer. However, the clinical use of DB remains a challenge due to its hepatotoxicity, which is caused, in part, by the presence of Diosbulbin B (DIOB), a toxin commonly found in DB extracts. As abnormal expression
Diosbulbin-B (DB) was the main compound of Dioscorea bulbifera L, which was widely used for cancer treatment in Asia. However, the hepatotoxicity induced by high-dose DB seriously limited its possibility using for gastric cancer (GC) treatment in clinic. In this study, we found that DB inhibited GC
Airpotato yam is a traditional Chinese medicine used for treating thyroid disease and cancer in China. Diosbulbin B (DB) is reported to be the main hepatotoxic compound isolated from Airpotato yam. A variety of reports have shown the acute liver injury induced by DB in vivo. However, whether
Aim: Diosbulbin B (DB) is a major diterpenoid compound found in Dioscorea bulbifera L, a traditional medicinal herb in China. Clinical reports have confirmed that Dioscorea bulbifera L. can induce significant hepatotoxicity. In this study, we showed that DB can induce
Diosbulbin B (DSB), a major component of herbal medicine Dioscorea bulbifera L. (DB), can be metabolized to an electrophilic intermediate, DSB-derived cis-enedial (DDE). DDE was suggested to contribute to the hepatotoxicity observed in experimental animals and humans after their exposure to DSB. Our
Diosbulbin B (DIOB), a furanoid, is a major constituent of herbal medicine Dioscorea bulbifera L. Exposure to DIOB caused liver injury in humans and experimental animals. The mechanisms of DIOB-induced hepatotoxicities remain unknown. The present study demonstrated that DIOB induced hepatotoxicities
The rhizome of Dioscorea bulbifera Linn, traditionally used to treat thyroid disease and cancer in China, is reported to induce serious liver injury during clinical practice. Diosbulbin B (DB), a diterpene lactone, has been found to be the main toxic compound in D. bulbifera. The present study aims
Dioscorea bulbifera L., a commonly used medicinal plant in China, is reported to induce hepatotoxicity. The present study is undertaken to investigate the hepatotoxicity induced by diosbulbin B (DB), a diterpene lactone isolated from D. bulbifera L., and to further explore its underlying mechanism.
Diosbulbin B (DB) is the main hepatotoxic compound in Airpotato yam, which is traditionally used for treating thyroid disease and cancer in China, and its hepatotoxic mechanism still remains unclear. This study aims to investigate its hepatotoxic mechanism by focusing on regulating microRNA (miRNA).
Dioscorea bulbifera L. (DBL), a traditional Chinese medicine, is a well-known herb with hepatotoxicity, and the biochemical mechanisms of the toxic action remain unknown. Diosbulbin B (DSB), a major component of DBL, can induce severer liver injury which requires cytochrome P450-catalyzed
Diosbulbin B (DIOB) is an effective component of air potato yam with anti-tumor and anti-inflammatory activities, and it is the main toxic component leading to hepatotoxicity. However, the mechanism of its hepatotoxicity remains unclear. In this study, we aimed to systematically elucidate the
Diosbulbin B (DIOB), a furan-containing diterpenoid lactone, is the most abundant component of Dioscorea bulbifera L. (DB), a traditional Chinese medicine herb. Administration of purified DIOB or DB extracts has been reported to cause liver injury in animals. The mechanisms of DIOB-induced
Diosbulbin B (DBB) and 8-epidiosbulbin E acetate (EEA), belonging to furan-containing diterpenoid lactones, are the primary components of Dioscorea bulbifera L. (DB), a traditional Chinese medicine herb. Our earlier studies indicated that consumption of DBB or EEA induced acute hepatotoxicities.
Diosbulbin B (DB), a major constituent of the furano-norditerpenes in Dioscorea bulbifera Linn, exhibits potential antineoplasmic activity and hepatotoxicity. The metabolism and reactive metabolites of DB in vitro (with human and animal liver microsomes) and in vivo in rats were investigated. The
