Topoisomerase II is the cytotoxic target for a number of clinically relevant antitumor drugs. Berberrubine, a protoberberine alkaloid which exhibits antitumor activity in animal models, has been identified as a specific poison of topoisomerase II in vitro. Topoisomerase II-mediated DNA cleavage
The antitumor activity of several 13-alkyl-berberrubine and newly synthesized ester derivatives, using experimental tumors (S-180, NF sarcoma, Ehrlich carcinoma and L-1210) in mice was tested. For chemotherapeutic evaluation, the therapeutic indices and ratios were determined. Our present findings
Berberrubine, an isoquinoline alkaloid isolated from many medicinal plants, possesses diverse pharmacological activities, including glucose-lowering, lipid-lowering, anti-inflammatory, and anti-tumor effects. This study aimed to investigate the metabolic profile of berberrubine in vivo. Therefore, a
A new series of 9-O-3-(1-piperazinyl/morpholinyl/piperidinyl)pentyl-berberines has been efficiently formulated via coupling 1,5-dibromopentane with berberrubine which was obtained by treating berberine in a vacuum oven at optimum temperature and pressure. Nucleophilic substitution of a variety of
[ 18F]HX-01, a Fluorine-18 labeled berberine derivative, is a potential positron emission tomography (PET) tumor imaging agent, while [ 19F]HX-01 is a nonradioactive reference substance with different energy state and has the same physical and chemical properties. In order to collect data for
Two-year toxicity studies were conducted on the widely used herbal products, goldenseal and milk thistle, in male and female F344/N rats and B6C3F1 mice. With goldenseal root powder, the primary finding was an increase in liver tumors in rats and mice, and with milk thistle extract, a decrease in
Epileptic seizures are characterized by synchronized discharges of neurons, leading to the activation of inflammatory responses that in turn contributes to seizure progression. Berberine (BBR), a bioactive constituent extracted from berberis, has been known to relieve seizures in rodent models. In
