Fatal strychnine poisoning is uncommon. It is no longer used as a therapeutic drug and its availability to the public is controlled by legislations in various jurisdictions, but it is still in use as a rodenticide and an adulterant in street drugs. Homicide by strychnine is extremely rare. As the autopsy findings are subtle, strychnine poisoning could easily be overlooked and a homicide may go undetected. This communication highlights an unusual case of homicide by strychnine. It is important that in deaths where there are no gross autopsy findings, sudden death in particular, that routine toxicology be performed, in which strychnine is likely to be detected.

Among the diabetes-related complications, diabetic nephropathy is the major complication and it leads to end-stage renal failure. In the current investigation, we examined the protection of brucine, an alkaloid extracted from the seeds of Strychnos nux vomica plant widely used in traditional Chinese and Indian medicines against diabetic-induced nephropathy. Male Wistar rats were divided into four groups: control, diabetic rats, diabetic-induced + 40 mg/kg brucine-treated rats, and diabetic-induced + 25 mg/kg metformin-treated rats.

Understanding the intricate interplay between structural features and signal-processing events is crucial for unravelling the mechanisms of biomolecular systems. G protein-coupled receptors (GPCRs), a pervasive protein family in humans, serve a wide spectrum of vital functions. TAS2Rs, a subfamily of GPCRs, play a primary role in recognizing bitter molecules and triggering events leading to the perception of bitterness, a crucial defence mechanism against spoiled or poisonous food.

Cancer is a serious threat to human life, health and social development. In recent years, nanomicelles, as an emerging drug carrier material, have gradually entered people's field of vision because of their advantages of improving bioavailability, maintaining drug levels, reducing systemic side effects and increasing drug accumulation at target sites. In this study, B-GPSG nano-micelles were prepared by film dispersion hydration method using brucine as model drug and glycyrrhetinic acid-polyethylene glycol-3-methylene glycol-dithiodipropionic acid-glycerol monostearate polymer as nano-carrier.

Prostate cancer (PCa) remains a leading cause of cancer-related incidence and mortality in men. Disruptions in amino acid (AA) metabolism contribute to the disease progression, with brucine, a glycine antagonist, exhibiting antitumor effects. This study explores the antitumor impact of brucine on PCa and investigates its mechanisms in regulating AA metabolic pathways.

Glycyrrhetinic acid-mediated brucine self-assembled nanomicelles enhance the anti-hepatitis B properties of brucine by improving its water solubility, short half-life, toxicity, and side effects. Brucine (B) is an indole alkaloid extracted from the seeds of (Loganiaceae). To assess the efficacy of the Brucine-Glycyrrhetnic acid-Polyethylene glycol-3,3'-dithiodipropionic acid-Glycerin monostearate (B-GPSG) in treating hepatitis B, its potential to protect against acute liver injury caused by d-galactosamine and its anti-hepatoma activities were studied.
