Background: Sigma receptors, N-methyl-D-aspartate (NMDA) antagonist, and modulators of intracellular calcium may be useful for seizure control. Therefore, we aimed to evaluate the antiepileptic effects of opipramol, a sigma receptor agonist, against pentylenetetrazole (PTZ)-induced seizures in mice and assess ketamine and caffeine interaction with the antiepileptic effects of opipramol.Methods:...

A new, simple, and sensitive spectrophotometric method for the determination of certain tricyclic antidepressants, belonging to the dibenzazepine class of drugs, has been developed. The proposed method is based on the reaction of imipramine hydrochloride (IPH), desipramine hydrochloride (DPH), clomipramine hydrochloride (CPH), trimipramine maleate (TPM) or opipramol (OPP) with iron(III), and su...

In the crystal structure of the title salt {systematic name: 4-[3-(5H-dibenz[b,f]azepin-5-yl)prop-yl]-1-(2-hy-droxy-eth-yl)piperazin-1-ium (2Z)-3-carb-oxy-prop-2-enoate}, C(23)H(30)N(3)O(+)·C(4)H(3)O(4) (-), the piperazine group in the opipramol cation is protonated at only one of the N atoms. In the cation, the dihedral angle between the two benzene rings is 53.5 (6)°. An extensive array of in...

1. The anticonvulsant potency of a series of structurally-dissimilar compounds which possess nanomolar affinities for high-affinity sigma binding sites was examined in the Mg2+-free model of epileptiform activity in rat hippocampal slices. Extracellular field potential recordings in the CA1 region were employed to examine the effects of test compounds on spontaneous epileptiform activity and mu...

Abstract The present studies were carried out to evaluate the simultaneous one-pot metabolism of opipramol (IS-opi) and analog (IS-noh) by phase I II enzymes in rat liver microsomes (RLM) as an alternative separate testing with recombinant enzymes. This approach allows for more time-saving cost-effective screening newly discovered drugs. We also considered that lack results II, including UGT, o...
