Bulleyaconitine A (BLA) from Aconitum bulleyanum plants is usually used as anti-inflammatory drug in some Asian countries. It has a variety of bioactivities, and at the same time some toxicities. Since the bioactivities and toxicities of BLA are closely related to its metabolism, the metabolites and
Background: Visceral pain is one of the most common types of pain and particularly in the abdomen is associated with gastrointestinal diseases. Bulleyaconitine A (BAA), isolated from Aconitum bulleyanum, is prescribed in China to
Background Oral administration of Bulleyaconitine A, an extracted diterpenoid alkaloid from Aconitum bulleyanum plants, is effective for treating chronic pain in rats and in human patients, but the underlying mechanisms are poorly understood. Results As the hyperexcitability of dorsal root ganglion
Bulleyaconitine A, a diterpenoid alkaloid isolated from Aconitum bulleyanum plants, has been used for the treatment of chronic pain in China since 1985. Clinical studies show that the oral administration of bulleyaconitine A is effective for treating different kinds of chronic pain, including back
BACKGROUND
Bulleyaconitine A (BLA) is an active ingredient of Aconitum bulleyanum plants. BLA has been approved for the treatment of chronic pain and rheumatoid arthritis in China, but its underlying mechanism remains unclear.
METHODS
The authors examined (1) the effects of BLA on neuronal
Aconitine and its structurally-related diterpenoid alkaloids have been shown to interact differentially with neuronal voltage-dependent sodium channels, which was suggested to be responsible for their analgesia and toxicity. Bulleyaconitine A (BAA) is an aconitine analogue and has been prescribed
OBJECTIVE
To study the chemical constituents of chloroform fraction from Aconitum bulleyanum.
METHODS
The compounds were isolated by various chromatographic techniques and identified by spectroscopic methods.
RESULTS
7 compounds were obtained and identified as yunaconitine (1), crassicaudine (2),
Aconitines, including bulleyaconitine A, probably the most bioactive and abundant alkaloids in Aconitum plant, are a group of diester C19-diterpenoid alkaloids with one acetylester group attached to C8 of the diterpenoid skeleton and one benzoylester group to C14. Hydrolysis of both groups is
