A potential anti-asthmatic drug, CR 2039, enhances the anticonvulsive activity of some antiepileptic drugs against pentetrazol in mice.

CR 2039 (4-(1H-tetrazol-5-yl)-N-[4-(1H-tetrazol-5-yl]phenylbenzam ide), in doses of 10, 20, and 100 mg/kg i.p., did not modify the seizure pattern observed after subcutaneous pentetrazol, administered at its CD97 of 90 mg/kg for the clonic phase.

GYKI 52466 [1-(4-aminophenyl)-4-methoxy-7,8-methylenedioxy-5H-2,3-benzodiazepine hydrochloride] and the anticonvulsive activity of conventional antiepileptics against pentetrazol in mice.

Excitatory amino acids participate in the generation of seizure activity. Consequently, the effects of GYKI 52466 [1-(4-aminophenyl)-4-methoxy-7,8-methylenedioxy-5H-2,3-benzodiazepine hydrochloride], an antagonist of glutamate-mediated events, on the protective activity of conventional antiepileptic drugs against pentetrazol were studied. GYKI 52466 (up to 10 mg/kg, i.

ACTH 4-9 analogue facilitates the antiimmobility effect of antidepressants and dopamine agonists in swimming rats.

Evidence exists that the 4-10 or 4-9 fragments of adrenocorticotropic hormone (ACTH) produce some behavioral effects in animals and in humans. The present study was designed to investigate whether ACTH 4-9 interferes with the effects of antidepressants: fluoxetine (FLU), fluvoxamine (FOX), selegiline (SEL) or dopamine agonists: piribedil (PRB) or quinpirol (QPR) in forced swimming test and in open field in rats. ACTH 4-9 was given in a single dose (25, 50 or 100 micrograms/kg) or for 7 days (50 micrograms/kg/day), alone or together with antidepressants or dopamine agonists.

Studies on the interaction of antidepressant drugs with adrenocorticotropic hormone or prednisone in rats.

The influence of adrenocorticotropic hormone (ACTH) and prednisone on the effects of amitriptyline (AMI), imipramine (IMI), mianserin (MIA) or nomifensine (NOM) was investigated in forced swimming and in open field tests. ACTH (50 I.U.

Influence of a potential anti-asthmatic drug, CR 2039, upon the anticonvulsive activity of conventional antiepileptics against maximal electroshock-induced seizures in mice.

CR 2039 [[4-(1H-tetrazol-5-yl)-N-(4-(1H-tetrazol-5-yl]phenylbenza m ide], in doses of 10, 50, and 100 mg/kg i.p., significantly elevated the threshold for electroconvulsions, increasing the CS50 (current strength 50% in mA) values from 6.
