Brucine is an alkaloid resembling strychnine but it is much less potent than strychnine. Brucine was first discovered in 1819 by Pelletier and Caventou in the bark of the Strychnos nux vomica tree. Brucine causes paralysis of the peripheral nerve endings and produces violent convulsions. Since brucine is a large chiral molecule, it has been used as an enantioselective recognition agent using in chiral resolution. While brucine has been shown to have good anti-tumor effects, on both hepatocellular carcinoma and breast cancer, its narrow therapeutic window has limited its use as a treatment for cancer. Brucine is also used in traditional Chinese medicine as an anti-inflammatory and analgesic agent, as well as in some Ayurveda and homeopathy drugs. Like strychnine, brucine also functions as antagonist at the glycine receptor and paralyzes the inhibitory neurons

CHEMICAL (ACHIRAL)

Conditions:

p-Toluenesulfonic acid (PTSA) is an organic compound with the formula CH3C6H4SO3H. An aromatic sulfonic acid, often used as a strong acid catalyst. p-Toluenesulfonic acid monohydrate has been used as a reducing agent for the reductive amination of ketones and aldehydes. In the presence of p-Toluenesulfonic acid monohydrate novel deazaflavin-cholestane hybrid compounds have been synthesized in a condensation reaction. 2-Phenylethyl alpha-glucoside has also been synthesized in the presence of p-Toluenesulfonic acid monohydrate. p-toluenesulfonic acid esters, are a common class of reagents used in the pharmaceutical industry as alkylating agents, catalysts, and in purification steps of the chemical synthesis of a drug substance.
