BRL-44408, a potent (Ki=8.5 nM) and selective (>50-fold) α2A-adrenoceptor antagonist (KB=7.9 nM). BRL-44408 revealed antidepressant- and analgesic-like activity through selective alpha2A-adrenoceptor antagonism. Preclinical characterization of the neurochemical and behavioural profile of BRL-44408 suggests that selective antagonism of alpha2A-adrenoceptors may represent an effective treatment strategy for mood disorders and visceral pain. BRL-44408 increases hippocampal noradrenalin release following systemic administration. BRL-44408 has potential therapeutic application in the treatment of extrapyramidal side effects produced by some antipsychotic medications.
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
