This study investigated the anticonvulsant activity of a new phthalazine tetrazole derivative, QUAN-0808 (6-(4-chlorophenoxy)-tetrazolo[5,1-a]phthalazine), in the mouse maximal electroshock (MES) seizure model. The neurotoxicity of QUAN-0808 was investigated using the rotarod neurotoxicity test in mice. QUAN-0808 exhibited higher activity (median effective(More)
The antidepressant-like effects of N-palmitoylethanolamide (PEA), a putative endocannabinoid, was investigated in mice using the tail suspension test (TST) and the forced swimming test (FST). In TST, PEA (10, 20, and 40 mg/kg) produced a statistically significant reduction in immobility (50, 32, and 34%, respectively, vs. the control group), whereas(More)
A series of novel 10-alkoxy-5, 6-dihydro-triazolo[4,3-d]benzo[f][1,4]oxazepine derivatives were synthesized and screened for their anticonvulsant activities by the maximal electroshock (MES) test and their neurotoxicity was evaluated by the rotarod neurotoxicity test (Tox). In the MES test, compound 10-Heptyloxy-5,(More)
A series of 1-substituted-6-(4H-1,2,4-triazol-4-yl)-3,4-dihydroquinolin-2(1H)-ones were designed, synthesized, and screened for their antidepressant and anticonvulsant activities. Interestingly, compounds 5i, 5j, 5m, and 5n led to significant reductions in the immobility time in the forced swimming test at a dose of 50 mg/kg, and exhibited higher levels of(More)
Herein, we described the syntheses and anticonvulsant activities of 7-(substituted-phenyl)-6,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidin-5(4H)-ones (1a-1o) and their derivatives. Most of the synthesized compounds exhibited potent anticonvulsant activities in the maximal electroshock test (MES). The most promising compound 1i showed significant anticonvulsant(More)
Hypoxia played an important role in the pathogenesis of AD. Hypoxia increased Aβ formation, then caused Alzheimer's disease. Calcium sensing receptor (CaSR) was involved in the regulation of cell growth, differentiation, hormonal secretion and other physiological function. Increasing evidence supported CaSR might play a more prominent role in susceptibility(More)
In the present study we describe the syntheses and anticonvulsant activity evaluation of 5-phenyl-[1,2,4]triazolo[4,3-c]quinazolin-3-amine derivatives. Their anticonvulsant activity and neurotoxicity were evaluated by the maximal electroshock seizure test (MES) and the rotarod test, respectively. The majority of the compounds prepared were effective in the(More)
A series of 4-(3-alkoxy-phenyl)-2,4-dihydro-[1,2,4]triazol-3-ones were synthesized using the appropriate synthetic route and evaluated experimentally in the maximal electroshock test; their neurotoxicities were evaluated by the rotarod neurotoxicity test. The structures of these compounds were confirmed by IR, MS, (1) H-NMR, and elementary analysis. All(More)
A series of 5-alkoxytetrazolo[1,5-c]thieno[2,3-e]pyrimidine derivatives were synthesized and their anticonvulsant and antidepressant activities were evaluated. Pharmacological tests showed that four of the synthesized compounds had weak anticonvulsant activity, while most of the compounds had excellent antidepressant activity. The most active compound was(More)
A new series of 7-alkoxy[1,2,4]triazolo[3,4-b]benzothiazol-3(2H)-ones were synthesized and evaluated for their anticonvulsant activities. Among these compounds, 7-propoxy[1,2,4]triazolo[3,4-b]benzothiazol-3(2H)-one (4c) and 7-butoxy[1,2,4]triazolo[3,4-b]benzothiazol-3(2H)-one (4d) showed the highest activity against maximal electroshock (MES)-induced tonic(More)
