aporphine/seizures

The anticonvulsant action of various aporphine derivatives that act on dopamine receptors has been investigated in two genetically determined animal models--DBA/2 mice with sound-induced seizures and baboons Papio papio with photically-induced seizures. Protection against the clonic and tonic phases

(-)-2,10,11-Trihydroxy-N-n-propylnoraporphine (TNPA,2c) has been synthesized from thebaine (3a), via northebaine (3b), normorphothebaine (2a), and alkylation to the N-propyl derivative 2b. O-Demethylation gave the desired product 2c. Compound 2c showed activity comparable to its 10,11-dihyroxy

BACKGROUND Nelumbo nucifera Geartn., known as sacred lotus, has been used traditionally in South East Asia as a traditional medicine for various CNS disorders including stress, fever, depression, insomnia, and cognitive conditions. OBJECTIVE To investigate the in vitro cannabinoid and opioid

The present study investigated the anticonvulsant and convulsant profiles of nantenine, an aporphine alkaloid found in several vegetal species. At lower doses (20-50 mg/kg, i.p.) the alkaloid proved to be effective in inhibiting pentylenotetrazol- (PTZ 100 mg/kg, s.c.) and maximal

The effect of nantenine, an aporphine alkaloid, on ATPase K+-dependent dephosphorylation was evaluated using p-nitrophenylphosphate (p-NPP) as substrate. Basal K+-p-NPPase activity was significantly increased with 3 x 10(-4) M, remained unchanged with 3 x 10(-6) M, 3 x 10(-5) M but was reduced with

OBJECTIVE Boldine is an aporphine alkaloid which is best known for its antioxidant, anti-inflammatory and cytoprotective characteristics. It seems that all these activities are related to boldine ability to scavenge reactive free radicals. As indicated by several pieces of evidence, free radicals
