Abstract
Benzene is a six-membered hydrocarbon ring system and if three carbon-hydrogen units of benzene ring are replaced by nitrogen atoms then triazine is formed. Triazines are present in three isomeric forms 1,2,3- triazine, 1,2,4-triazine, and 1,3,5-triazine according to the position of the nitrogen atom. These are weak bases having weaker resonance energy than benzene, so nucleophilic substitution is preferred than electrophilic substitution. Triazine is an interesting class of heterocyclic compounds in medicinal chemistry. Numerous synthetic derivatives of triazine have been prepared and evaluated for a wide spectrum of biological activities in different models with desired findings such as antibacterial, antifungal, anti-cancer, antiviral, antimalarial, antiinflammatory, antiulcer, anticonvulsant, antimicrobial, insecticidal and herbicidal agents. Triazine analogs have exposed potent pharmacological activity. So, triazine nucleus may be considered as an interesting core moiety for researchers for the development of future drugs.

Raloxifene potentiates the effect of fluoxetine against maximal electroshock induced seizures in mice. Eur J Pharm Sci 2020; 146:105261. [PMID: 32061655 DOI: 10.1016/j.ejps.2020.105261] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 01/24/2020] [Accepted: 02/07/2020] [Indexed: 01/17/2023]
Abstract
The evidence to guide clinicians regarding rationale polytherapy with current antiepileptic drugs (AEDs) is lacking, and current practice recommendations are largely empirical. The excessive drug loading with combinatorial therapies of existing AEDs are associated with escalated neurotoxicity, and that emergence of pharmacoresistant seizures couldn't be averted. In pursuit of judicious selection of novel AEDs in combinatorial therapies with mechanism based evidences, standardized dose of raloxifene, fluoxetine, bromocriptine and their low dose combinations, were experimentally tested for their impact on maximal electroshock (MES) induced tonic hind limb extension (THLE) in mice. Hippocampal neuropeptide Y (NPY) levels, oxidative stress and histopathological studies were undertaken. The results suggest the potentiating effect of 4 mg/kg raloxifene on 14 mg/kg fluoxetine against MES induced THLE, as otherwise monotherapy with 4 mg/kg raloxifene was unable to produce an effect. The results also depicted better efficacy than carbamazepine (20 mg/kg), standard AED. Most profoundly, MES-induced significant (P < 0.001) reduction in hippocampal NPY levels, that were escalated insignificantly with the duo-drug combination, suggesting some other mechanism in mitigation of electroshock induced seizures. These results were later corroborated with assays to assess oxidative stress and neuronal damage. In conclusion, the results demonstrated the propitious therapeutic benefit of duo-drug low dose combination of drugs; raloxifene and fluoxetine, with diverse mode of actions fetching greater effectiveness in the management of generalized tonic clonic seizures (GTCS).
