BGC 20-761, is a selective high affinity 5-HT6 antagonist (Ki = 20 nM). that has shown to enhance memory consolidation in a rat model. It reverses he amnesic effects of Scopolamine (S200000).
bgc20-761 is a selective and high affinity antagonist of 5-htc.the 5-ht6 receptor, a g protein-coupled receptor (gpcr), is a subtype of 5-ht receptor which binds the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-ht). this protein is expressed almost exclusively in the brain and mediates excitatory neurotransmission.in cellular level, bgc20-761 (5-methoxy-2-phenyl-n,n-dimethyltryptamine) was shown to selectively blocked 5-htc.bgc20-761 was used to study the difference in drug- induced effects in memory consolidation in young and mature rats and human. in young mice, bgc20-761 treatment at doses of 5 mg/kg and 10 mg/kg i.p, dose-dependently reversed a deficit of social recognition induced by scopolamine, an anticholinergic drug that impairs memory at dosage of 0.4 mg/kg i.p. in mature rats (6 months), recognition of the novel object was improved following administration of bgc20-761. the difference in effects of bgc20-761 in young vs. mature rats may reflect the status of memory consolidation in these different age ranges 1.
