Cocaine binds to sigma receptors with comparable affinity to its well-established interaction with dopamine transporters. Previous studies have shown BD1008 (N-[2-(3,4-dichlorophenyl)ethyl]-N-methyl-2-(1-pyrrolidinyl)ethylamine) to have high affinity and selectivity for sigma receptors, and to
A variety of neurotransmitter receptor changes occur after a course of electroconvulsive seizures (ECS) in rats, including an increased density of adenosine A1 sites. Adenosine antagonism has been related to the proconvulsant action of methylxanthines such as caffeine. We determined tonic-clonic
Thirty-six allyl substituted oxopyrimidine analogues such as barbituric acid (BA), barbiturates, uracil, thymine, and related derivatives including 13 new compounds were synthesized and their pharmacologic effects ([hypnotic activity, anticonvulsant activity against pentylentetrazol (PTZ)-induced
Twenty four thiouracil derivatives, including N3-allyl- (19) and N1-allyl-2-thiouracil (20) were synthesized and their pharmacological effects [sedative-hypnotic activity (loss of righting reflex and spontaneous activity), convulsant activity, effect on pentobarbital (PB)-induced sleep and
Pharmacological activities (hypnotic, anticonvulsant and convulsant activities, acute toxicity and pentobarbital (PB) synergism) of N-allyl,N'-methyl derivatives of barbiturates and related N-allyl substituted compounds were studied in mice. N-Allylhexobarbital (AHB), N-allylglutethimide (AGI) and
Delta opioid receptor (DOR) selective agonists hold promise clinically as analgesics, but their effects on seizures remain controversial. In this study we examined the effects of the DOR agonist, (+)-4-[(alpha
The anticonvulsant activity (ED50) of three synthetic eugenol derivatives - phenyleugenol (PE), benzyleugenol (BE), phenylethyleugenol (PEE) - was compared to that of common antiepileptics - diphenyl-hydantoin (DPH), phenobarbital (PB), diazepam (DZ) - and the naturally occurring methyleugenol (ME)
δ opioid peptide (DOP) receptors are considered a therapeutic target in Parkinson's disease, although the use of DOP agonists may be limited by side effects, including convulsions. To circumvent this issue, we evaluated whether blockade of nociceptin/orphanin FQ (N/OFQ) tone potentiated the
The specificity of the hypoglycemic response to the intrathecal (i.t.) administration of the naturally occurring (-)-enantiomer of morphine previously reported from our laboratory was studied in mice. (+)-Morphine HBr (50 micrograms) caused a behavioral syndrome (scratching, biting, seizures)
In order to examine the effects of N-substituted alkyl group on the anticonvulsant activities of N-Cbz-alpha-aminoglutarimides as novel anticonvulsants with broad spectrum, a series of (R) or (S) N-Cbz-alpha-amino-N-alkylglutarimides (1 and 2) were prepared from the corresponding (R) or (S)
We have explored the structure-activity relationship (SAR) surrounding the clinically efficacious antiepileptic drug topiramate (1), a unique sugar sulfamate anticonvulsant that was discovered in our laboratories. Systematic structural modification of the parent compound was directed to identifying
Pharmacological activities (hypnotic activity, anticonvulsant activity against pentylenetetrazol (PTZ)-induced seizures and motor incoordination) of N-allyl substituted derivatives of barbital (B) were investigated using mice. N-Monoallylbarbital (MAB) was found to possess more potent hypnotic
Responding by squirrel monkeys was maintained by food presentation under a repeated acquisition of behavioral chains procedure. Monkeys acquired a different three-response chain each session. Sequence completions were reinforced under a fixed-ratio 5 schedule, whereas errors produced a brief time
The squirrel monkey titration procedure was used to assess the antinociceptive effects of the novel delta opioid agonist (+/-)-4-(a-R*)-a(2S*,5R*)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-hydroxyb enzyl)- N,N-diethylbenzamide (BW373U86). Under this procedure shock increased every 15 sec from 0.01 to
Effects of SK&F 83822 [3-allyl-6-chloro-7,8-dihydroxy-1-(3-methylphenyl)-2,3,4,5-tetrahydro-1H-3-benzazepine], an agonist at dopamine D1-like receptors which stimulate adenylyl cyclase but not phosphoinositide hydrolysis, were studied topographically so as to clarify differences between these
