A rare case of brucine poisoning complicated by rhabdomyolysis and acute renal failure.

Abstract: Brucine is the predominant alkaloid present in the bark of the tree Strychnos nux vomica and is a weaker alkaloid when compared to strychnine. However, its toxicological property is akin to strychnine. We report a rare case of brucine poisoning complicated by acute renal failure and rhabdomyolysis. A 24-year-old male presented with a history of consumption of a decoction made from the bark of the Strychnos nux vomica tree. Soon after, he developed widespread muscle spasms and convulsions, which were promptly treated. On the fifth day of admission, he developed features of rhabdomyolysis and acute renal failure. Investigations revealed elevated creatine phosphokinase levels and elevated blood urea and serum creatinine. The patient was managed with hemodialysis and recovered gradually. There are many reports of strychnine poisoning producing rhabdomyolysis and renal failure. In this case report, attention is drawn to the fact that brucine, although a weaker alkaloid, can also produce life threatening complications like rhabdomyolysis and acute renal failure.

Molecular Recognition in Proton-Transfer Compounds of Brucine with Achiral Substituted Salicylic Acid Analogues

Abstract: The 1:1 proton-transfer brucinium compounds from the reaction of the alkaloid brucine with 5-nitrosalicylic acid, 3,5-dinitrosalicylic acid, and 5-sulfosalicylic acid, namely anhydrous brucinium 5-nitrosalicylate (1), brucinium 3,5-dinitrosalicylate monohydrate (2), and brucinium 5-sulfosalicylate trihydrate (3) have been prepared and their crystal structures determined by X-ray crystallography. All structures further demonstrate the selectivity of brucine for meta-substituted benzoic acids and comprise three-dimensional hydrogen-bonded framework polymers. Two of the compounds (1 and 3) have the previously described undulating brucine sheet host-substructures which incorporate interstitially hydrogen-bonded salicylate anion guest species and additionally in 3 the water molecules of solvation. The structure of 2 differs in having a three-centre brucinium–salicylate anion bidentate N+–H···O(carboxyl) hydrogen-bonding association linking the species through interstitial associations involving also the water molecules of solvation. A review of the crystallographic structural literature on strychnine and brucine is also given.

Novel alkaloid modifiers for enantioselective heterogeneous catalysis

Abstract: The alkaloids codeine, 7,8-dihydrocodeine, brucine and strychnine, when adsorbed on Pt/silica (EUROPT-1) induce enantioselectivity and enhance the rate of hydrogenation of the carbonyl function in methyl pyruvate and in butane-2,3-dione.
