Abstract
Formononetin as a Bax agonist exhibits anticancer effects. To identify novel Bax agonist, 18 new structurally modified formononetin derivatives were synthesised and their anticancer activities were evaluated in the A549 and Beas-2b cell lines. The results indicated that 7a elicited the most potent inhibitory effect against the A549 cell line, with an IC50 value of 0.87 μM, and no obvious toxicity to Beas-2b cells. These results indicated that 7a was 40-fold and 6.94-fold more efficacious than Formononetin and Doxorubicin, respectively. Additionally, western blot and immunofluorescence assays demonstrated that 7a downregulated the protein expression of Bcl-2 and upregulated the expressions of Bax to promote A549 apoptosis, the obtained results also suggested that 7a had the potential to be developed into a lead compound that can be applied in the prevention and treatment of lung cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sugemule-3 decoction (SD-3) is a commonly used prescription in Mongolian medicine which composed of the herbs Baidoukou (the fruit of Amomum compactum Sol. ex Maton), Baijusheng (the fruit of Lactuca sativa L.) and Biba (Piper longum L.). SD-3 has remarkable effect on the cardiovascular diseases, but its pharmacological mechanism has not been elucidated. AIM OF THIS STUDY To evaluate the cardioprotective effects and the potential mechanisms of the ethanol extracts of SD-3 against isoproterenol (ISO)-induced heart failure (HF) in rats. MATERIAL AND METHODS The ethanol extracts of SD-3 were prepared and analyzed by LC-ESI-MS/MS. One hundred male Wistar rats were randomly divided into five groups: control, ISO (HF) and different doses of SD-3 (0.4, 0.2, 0.1 g/kg/d) groups. HF model rats were established by intraperitoneal injecting of ISO. The left ventricular function was evaluated by echocardiography. Myocardial injury and fibrosis were examined by hematoxylin-eosin (HE) and Masson staining. Western-blot analysis was performed to determine the protein expression of apoptosis and mitochondrial dynamics in all the groups. Moreover, the structural changes in the mitochondria of cardiomyocytes were also observed by transmission electron microscopy. RESULTS Fifteen compounds were detected in the ethanol extracts of SD-3, include piperine, piperanine, etc. Rats administered with ISO showed a significant decline in the left ventricular function. The cardiac histopathological changes such as local necrosis, interstitial edema, and cardiac fibrosis were also observed in the ISO group. The treatment with SD-3 significantly inhibited these effects of ISO. ISO was found to increase the protein expression of Bax, cleaved-PARP and cleaved-caspase-3, -7 -9, destroy the balance between mitochondrial fusion and fission, and alter the mitochondrial morphology. The ethanol extracts of SD-3 could rebalance mitochondrial fusion and fission, and ameliorates the morphological abnormalities induced by ISO in mitochondria. CONCLUSION The current study demonstrated that ethanol extracts of SD-3 improved isoprenaline-induced cardiac hypertrophy and fibrosis through inhibiting cardiomyocyte apoptosis and regulating the mitochondrial dynamics.

Abstract
BACKGROUND Interleukin (IL)-18 is produced mainly in the heart, and can be associated to the development of cardiac hypertrophy that leads to cardiac dysfunction. However, the effects of hypoxia on IL-18 expression and atrial natriuretic factor (ANF) secretion remain largely unknown. AIM To assess the effect of hypoxia on IL-18 production and its role in ANF secretion by using an isolated perfused beating rat atrial model. METHODS The level of ANF in the perfusates was determined by radioimmunoassay, and the protein levels of Src, IL-18 and its receptors (IL-18-Rα and IL-18-Rβ), Rho guanine nucleotide exchange factor (RhoGEF) and RhoA, activating transcription factor 3 (ATF3), T cell factor (TCF) 3 and 4, and lymphoid enhancer factor (LEF) 1 in atrial tissue samples were detected by Western blotting. RESULTS Hypoxia significantly upregulated the expression of non-receptor tyrosine kinase Src, and this effect was blocked by endothelin-1 receptor type A (BQ123) and type B (BQ788) antagonists. Hypoxia also enhanced the expression of RhoGEF and RhoA concomitantly with the upregulation of IL-18, IL-18-Rα and IL-18-Rβ. The hypoxia-induced RhoGEF and RhoA were abolished by Src inhibitor 1 (SrcI), and the protein levels of IL-18 and its two receptors were also blocked by SrcI. Moreover, the hypoxia-induced expression levels of ATF3, TCF3, TCF4 and LEF1 were repealed by IL-18 binding protein, and the hypoxia-promoted secretion of ANF was also obviously attenuated by this binding protein. CONCLUSIONS These findings imply that Src-IL-18 signaling is involved in the release of ANF in hypoxic beating rat atria.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The traditional Chinese medicine Sanweidoukou decoction (DK-3) was a classical formula for the treatment of nervous system diseases, recorded in the Chinese medical classic Sibu Yidian. AIM OF THE STUDY The present study is aim to investigate the neuroprotective effects of DK-3 on β-amyloid (Aβ) protein -induced AD-like pathologies and underlying molecular mechanisms both in vitro and in vivo studies. MATERIALS AND METHODS Hydrolysates of DK-3 were analyzed by LC-ESI-MS/MS. In vitro, MTT was utilized to examine effects of DK-3 on Aβ25-35-induced cytotoxicity in PC12 cells. In vivo, male Sprague-Dawley rats were administered with Aβ25-35 to induce AD-like pathologies and behavioral evaluations were conducted via Morris water maze (MWM) test. Histopathological changes were observed by Hematoxylin-eosin (HE) straining. Immunohistochemistry (IHC) was used to detect the tau hyperphosphorylation at Thr181 site. The expression levels of tau hyperphosphorylation, inflammation-related cytokines such as COX-2, iNOS, TNF-α, IL-1β, IL-6, the phosphorylated state of various mitogen-activated protein kinase (MAPK) signaling molecules (p38 MAPK, ERK, and JNK) and activation of nuclear factor κB (NF-κB) in vitro and in vivo were assessed via Western blot. RESULTS In vitro, DK-3 dose-dependently increased cell viability of PC12 cells induced by Aβ25-35. In vivo, DK-3 improved learning and memory abilities of Aβ25-35-induced AD-like rats. Moreover, DK-3 reversed hyperphosphorylation of tau and reduced the production of inflammation-related cytokines through significantly inhibited MAPK and NF-κB signaling pathways both in vitro and in vivo studies. CONCLUSION The present study suggested that the traditional Chinese medicine DK-3 may play a role in preventing and treating AD by reducing the hyperphosphorylation of tau protein and the expressions of inflammation-related cytokines via modulating the MAPK/NF-κB signaling pathways.

Abstract
Nicotinamide adenine dinucleotide phosphate oxidases (NOXs) are the major enzymatic source of reactive oxygen species (ROS). NOX2 and NOX4 are expressed in the heart but its role in hypoxia-induced atrial natriuretic peptide (ANP) secretion is unclear. This study investigated the effect of NOX on ANP secretion induced by hypoxia in isolated beating rat atria. The results showed that hypoxia significantly upregulated NOX4 but not NOX2 expression, which was completely abolished by endothelin-1 (ET-1) type A and B receptor antagonists BQ123 (0.3 µM) and BQ788 (0.3 µM). ET-1-upregulated NOX4 expression was also blocked by antagonists of secreted phospholipase A2 (sPLA2; varespladib, 5.0 µM) and cytosolic PLA2 (cPLA2; CAY10650, 120.0 nM), and ET-1-induced cPLA2 expression was inhibited by varespladib under normoxia. Moreover, hypoxia-increased ANP secretion was evidently attenuated by the NOX4 antagonist GLX351322 (35.0 µM) and inhibitor of ROS N-Acetyl-D-cysteine (NAC, 15.0 mM), and hypoxia-increased production of ROS was blocked by GLX351322. In addition, hypoxia markedly upregulated Src expression, which was blocked by ET receptors, NOX4, and ROS antagonists. ET-1-increased Src expression was also inhibited by NAC under normoxia. Furthermore, hypoxia-activated extracellular signal-regulated kinase 1/2 (ERK1/2) and protein kinase B (Akt) were completely abolished by Src inhibitor 1 (1.0 µM), and hypoxia-increased GATA4 was inhibited by the ERK1/2 and Akt antagonists PD98059 (10.0 µM) and LY294002 (10.0 µM), respectively. However, hypoxia-induced ANP secretion was substantially inhibited by Src inhibitor. These results indicate that NOX4/Src modulated by ET-1 regulates ANP secretion by activating ERK1/2 and Akt/GATA4 signaling in isolated beating rat hypoxic atria.

Abstract
A series of novel synthetic substituted benzo[d]oxazole-based derivatives (5a-5v) exerted neuroprotective effects on β-amyloid (Aβ)-induced PC12 cells as a potential approach for the treatment of Alzheimer's disease (AD). In vitro studies show that most of the synthesized compounds were potent in reducing the neurotoxicity of Aβ25-35-induced PC12 cells at 5 μg/mL. We found that compound 5c was non-neurotoxic at 30 μg/mL and significantly increased the viability of Aβ25-35-induced PC12 cells at 1.25, 2.5 and 5 μg/mL. Western blot analysis showed that compound 5c promoted the phosphorylation of Akt and glycogen synthase kinase (GSK-3β) and decreased the expression of nuclear factor-κB (NF-κB) in Aβ25-35-induced PC12 cells. In addition, our findings demonstrated that compound 5c protected PC12 cells from Aβ25-35-induced apoptosis and reduced the hyperphosphorylation of tau protein, and decreased the expression of receptor for AGE (RAGE), β-site amyloid precursor protein (APP)-cleaving enzyme 1 (BACE1), inducible nitric oxide synthase (iNOS) and Bcl-2-associated X protein/B-cell lymphoma 2 (Bax/Bcl-2) via Akt/GSK-3β/NF-κB signaling pathway. In vivo studies suggest that compound 5c shows less toxicity than donepezil in the heart and nervous system of zebrafish.

Abstract
One new aryldihydronaphthalene-type lignan (1) together with eight known lignans (2-4, 7-11) as well as two caffeic-acid dimers (5, 6) were isolated from an ethanol extract of the whole plant of Corispermum mongolicum Iljin (Chenopodiaceae). The chemical structures of these compounds were determined from 1D and 2D NMR and HR-ESI-MS spectra, and results were compared with data from the literature. This study is the first demonstration of nine compounds (2 and 4-11) isolated from the Chenopodiaceae family, with one of these (3) from the genus Corispermum. Anti-inflammatory effects of the isolated compounds were evaluated in terms of inhibition of production of nitric oxide, tumour necrosis factor-α, and interleukin-6 in lipopolysaccharide-induced RAW 264.7 cells.

Abstract
BACKGROUND/AIMS Temporal lobe epilepsy (TLE) is the most common form of adult localization-related epilepsy that is accompanied by progressive etiopathology and high incidences of drug resistance. Circular RNAs (circRNAs) play important roles in fine-tuning gene expression, however, the expression profile and clinical significance of circRNAs in TLE remains unknown. METHODS Circular RNA microarray was conducted to identify TLE-related circRNAs. CCK8 assays and flow cytometric assays were conducted to clarify the role of circRNA in TLE in vitro. Bioinformatics analysis and in vitro experiments were conducted to clarify the mechanism of circRNA-mediated gene regulation in TLE cell. RESULTS 586 differentially expressed circRNAs were identified between TLE and the control tissues. The expression of circRNA-0067835 was significantly down-regulated in tissues and plasma from TLE patients. Lower circRNA-0067835 correlated to increased seizure frequency, HS, and higher Engel's score. Overexpression of circRNA-0067835 observably decreased SH-SY5Y cell proliferation by causing G1 arrest and promoting apoptosis. Bioinformatics online programs predicted that circRNA-0067835 acted as miR-155 sponge to regulate FOXO3a expression, which was validated using luciferase reporter assay. CONCLUSION Our experiments showed that circRNA-0067835 regulated refractory epilepsy progression by acting as a sponge of miR-155 to promote FOXO3a expression, indicating that circRNA-0067835 may serve as a potential therapeutic target for patients with TLE.

Abstract
Background Micro-RNAs (miRNAs) are small non-coding RNAs that modulate many target genes. Viral myocarditis is common cardiomyopathy, however, there is an absence of effective therapeutic strategies for viral myocarditis (VMC). The purpose of this research was to characterize changes in miRNAs expression in VMC mice. Methods Atrial myocytes were infected coxsackievirus B3 and miRNAs microarray was performed. miRNAs target predicted and the bioinformatics analysis was carried out by gene ontology (GO) and KEGG pathway analysis. To validate the results, Difference miRNAs were identified in heart of mice by real-time polymerase chain reaction (PCR). Results We identified 94 miRNAs that were differentially expressed (27 were up-regulated and 67 were down-regulated by at least 2.0-fold). Real time PCR analysis has confirmed that the expression levels of 7 miRNAs up-regulated, 18 miRNAs down-regulated. They were mainly involved in protein binding, small GTPase mediated signal transduction, protein phosphorylation by GO. Pathway analysis showed that a significant enrichment in several pathways related to cAMP signaling pathway, AMPK signaling pathway, RAS signaling pathway, Rap1 signaling pathway, ErbB signaling pathway, Oxytocin signaling pathway. Conclusions Our results provide a better understanding of the mechanisms of viral myocarditis pathophysiology.

Abstract
OBJECTIVE To investigate the effects of total flavonids of astragalus(TFA) on arrhythmia, endoplasmic reticulum stress and connexcin in mice with viral myocarditis and to clarify the mechanisms of TFA against viral myocarditis complicated with arrhythmia. METHODS Thirty-six male Balb/c mice were randomly divided into control group, viral myocarditis group and total flavonoids group (n=12). The mice of viral myocarditis were intraperitonealy injected with 0.1 ml/day 10-950 TCID CVB3 for 3 days. The mice of TFA group were intraperitoneal injected with 0.1 ml/day 10-950 TCID CVB3 for 3 days and treated with 0.1ml, 20 mg/L TFA by tail vein injection. At the end of the experiment, arrhythmia was detected by electrocardiogram, the heart of mice were stained by HE, the expressions of glucose-regulated protein 78(GRP78), endoplasmic reticulum stress signaling pathway factor activating transcription factor 4(ATF4) and connexcin 43(Cx43) were detected by Western blot. RESULTS The expressions of GRP78 and ATF4 were increased and the expression of Cx43 was decreased in viral myocarditis, while TFA inhibited these effect of viral myocarditis in heart of mice. CONCLUSIONS The antiarrhythmic effect of TFA may be related to the alleviation of endoplasmic reticulum stress and the increase of Cx43 expression.

Abstract
Mesial temporal lobe epilepsy (mTLE), the most common type of temporal lobe epilepsy (TLE), is particularly relevant due to its high frequency of therapeutic resistance of anti-epileptic therapies. MicroRNAs (miRNAs) have been shown to be dysregulated in epilepsy and neurodegenerative diseases, and we hypothesized that miRNAs could be involved in the pathogenesis of MTLE. The present study aimed to explore the expression and functions of miRNA-153 in mTLE. The expression levels of miRNA-153 in refractory TLE patients were evaluated. The bioinformatics analysis showed that the potential target genes of miR-153 were involved in biological processes, molecular functions, and cellular components. miRNA-153 is significantly dysregulated in temporal cortex and plasma of mTLE patients. We identify HIF-1α as a direct target of miRNA-153, and luciferase reporter assays demonstrated that miR-153 could regulate the HIF-1αexpression via 3'-UTR pairing. These data suggest that miR-153 might represent a useful biomarker and treatment target for patients with mTLE.

Abstract
Background: Sugemule-3 (SD) is a traditional Chinese medicine with protective effect of myocardium. However, the underlying mechanisms of the effect had not been elucidated. Materials and Methods: In the present study, the serum of SD was prepared. A model of β-adrenergic agonist isoprenaline (ISO)-induced H9c2 cardiomyocytes injury was established in vitro. The changes in cell viability were examined to determine the available concentration of ISO and serum of SD. ELISA, terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay, and flow cytometry were used to detect the effect of serum of SD on oxidative stress and apoptosis. The expression levels of the mitochondria-dependent apoptotic pathway and mitogen-activated protein kinase signalling-related proteins were analyzed. Results: Incubation with different dose of ISO (0.015, 0.01, 0.005, and 0.0025 mol/L) for 24 h caused dose-dependent loss of cell viability and 0.01 mol/L of ISO approximately reduced the cell viability to 50%. Pretreatment with 50 μ mol/L serum of SD effectively decreased the levels of ISO-induced cell toxicity. Serum of SD relived ISO-induced oxidative stress and apoptosis in H9c2 cardiomyocytes. A further mechanism study indicated that serum of SD inhibited the mitochondria-dependent apoptotic pathways and regulated the expression levels of Bcl-2 family. ISO activated ERK and P38, whereas serum of SD inhibited their activation. Conclusion: Serum of SD inhibits the ISO-induced activation of the mitochondria-dependent apoptotic pathway, oxidative stress, and ERK, P38 inactivation. Serum of SD is used for the treatment of ISO-induced cardiomyopathy. SUMMARY The serum of SD pretreatment significantly ameliorated ISO-induced H9c2 cardiomyocytes injuries. The protective effect related with apoptosis and oxidative stress Inhibition of MAPK pathway was involed in serum of SD induced cardioprotection. The serum of SD is used for the treatment of ISO-induced cardiomyopathy.

Abstract
Viral myocarditis (VMC) is a common disease causing heart failure (HF) for which no specific treatments are available. As apoptosis of cardiomyoctes is a hallmark of VMC and HF, strategies targeting apoptosis are an effective way of prevention and treatment of HF. Recent studies found endoplasmic reticulum stress (ERS) reaction is a new signal transduction pathway mediating apoptosis. Calumenin protein (CP) is located within the endoplasmic reticulum Ca2+ binding proteins, and is important in ER-initiated apoptosis. The aim of this study was to investigate whether the function of CP was influenced in cardiomyocytes infected by coxsackievirus B3. The expression of CP was down-regulated in cardiomyocytes infected by coxsackievirus B3. TUNEL studies showed that apoptosis was increased in CP-deficient and ΔCP-mutant cardiomyocytes infected by coxsackievirus B3. Additionally, ERS-associated proteins (GRP78, p-PERK, p-eIF2α, ATF4 and CHOP) were up-regulated in coxsackievirus B3-infected CP-deficient and ΔCP-mutant cardiomyocytes compared to wild type control cells. These results suggested ER-initiated apoptosis was induced by coxsackievirus B3-infected cardiomyocytes and caused apoptosis through ER stress. CP can relieve ERS-initiated apoptosis in viral myocarditis.

Abstract
Atrial fibrillation (AF) is a complex disease with multiple inter-relating causes culminating in rapid atrial activation and atrial structural remodeling. The contribution of endoplasmic reticulum and mitochondria stress to AF has been highlighted. As the class III antiarrhythmic agent, ibutilide are widely used to AF. This study was designed to explore whether ibutilide could treat AF by inhibiting endoplasmic reticulum stress pathways and mitochondria stress. The neonatal rat cardiomyocytes were isolated and exposed to H2O2, ibutilide was add to the culture medium 12 h. Then the cell viability, oxidative stress levels and apoptotic rate were analyzed. In addition, endoplasmic reticulum stress related protein (GRP78, GRP94, CHOP), mitochondria-dependent protein (Bax, Bcl-2) and caspase-3/9/12 were identified by real-time PCR and western blot analysis. In our results, remarkable decreased cell viability and oxidative stress levels were detected in cardiomyocytes after treating with H2O2. The apoptotic rate and the expression of proteins involved in mitochondrial stress and endoplasmic reticulum stress pathways increased. While ibutilide significantly inhibited these changes. These data suggested that ibutilide serves a protective role against H2O2-induced apoptosis of neonatal rat cardiomyocytes, and the mechanism is related to suppression of mitochondrial stress and endoplasmic reticulum stress.

Abstract
Epilepsy affects about 1% of the world’s population. Due to the fact all antiepileptic drugs (AEDs) have some undesirable side effects and about 30% of epileptic patients are not seizure-free with the existing AEDs, there is still an urgent need for the development of more effective and safer AEDs. Based on our research work on antiepileptic compounds and other references in recent years, this review covers the reported work on antiepileptic compounds which are classified according to their structures. This review summarized 244 significant anticonvulsant compounds which are classified by functional groups according to the animal model data, although there are some limitations in the data. This review highlights the properties of new compounds endowed with promising antiepileptic properties, which may be proven to be more effective and selective, and possibly free of unwanted side effects. The reviewed compounds represent an interesting possibility to overcome refractory seizures and to reduce the percentage of patients with a poor response to drug therapy.

Abstract
The aim of the present paper was to find new compounds with stronger anticonvulsant activity and lower neurotoxicity, a novel series of 6-substituted-pyrido[3,2-d]pyridazine derivatives was synthesized using furo[3,4-b]pyridine-5,7-dione as the starting material. Their anticonvulsant activities were evaluated by the maximal electroshock test (MES) and their neurotoxicity was measured by the rotarod test. The results of these tests demonstrated that N-m-chlorophenyl-[1,2,4]triazolo- [4,3-b]-pyrido[3,2-d]pyridazin-6-amine (3) was the most potent anticonvulsant, with ED50 value of 13.6 mg/kg and protective index (PI = TD50 / ED50) values of 7.2 in the MES test. Compound N-m-chlorophenyltetriazolo[5,1-b]-pyrido[3,2-d]pyridazin-6-amine (19), exhibited a little weaker activity than compound 3 in controlling the seizure induced by MES test at the dose of 15.9 mg/kg, but it possessed lower neurotoxicity with PI value of 13.4, which was safer than marketed drug carbamazepine.

Abstract
The present study describes the chemical synthesis and anticonvulsant activity evaluation of a series of 7-alkoxy-triazolo-[3, 4-b]benzo[d]thiazoles. Most compounds exhibited good anticonvulsant activity in the Maximal electroshock (MES) test. And the structure-activity relationships (SAR) were analyzed. Among the compounds studied, 7-octyloxy-triazolo-[3, 4-b]benzo[d]thiazole (5g) was found to be the most potent compound with a median effective dose (ED(50)) value of 8.0 mg/kg and a protective index (PI) value of 15.0, possessing better anticonvulsant activity and higher safety than marketed drugs carbamazepine and phenytoin. The mechanism study of compound 5g showed that it displayed broad spectrum activity in several models, and it is likely to have several mechanisms of action (including inhibiting voltage-gated ion channels and GABAergic activity).

Abstract
The present study describes the chemical synthesis and pharmacological evaluation of a series of 9-alkoxy-7H-furo[3,2-g]-chromen-7-ones. The pharmacological results of these compounds show that nine of them, given orally, reduced the immobility time in the forced swimming test. The results of the open-field test further confirmed that these compounds possessed an antidepressant-like effect. In the 5-hydroxytryptophan induced head-twitch test, 9-(3-chlorobenzyloxy)-7H-furo[3,2-g]chromen-7-one (3 m, 40 mg/kg p. o.) significantly increased the cumulative numberof head twitches. This finding suggested that the antidepressant-like profile seems to involve the serotonergic system as underlying mechanism.

Abstract
A new series of 6-alkyoxyl-tetrazolo[5,1-a] phthalazine derivatives (4 a-4 o) were synthesized as potential anticonvulsant agents. Anticonvulsant activity was evaluated by the maximal electroshock (MES) test. Neurotoxicity was evaluated by the rotarod neurotoxicity test. The pharmacological results showed that 6-(4-chlorophenyoxyl)-tetrazolo[5,1-a]phthalazine (4 m) was the most potent agent, with a median effective dose (ED50) of 6.8 mg/kg and a median neurotoxic dose (TD50) of 456.4 mg/kg. The protective index (PI = TD50/ED50) for compound 4 m was 67.1, which was significantly higher than that for the reference drug carbamazepine (PI = 6.4).

Abstract
A series of 7-alkoxy-2H-1,4-benzothiazin-3(4H)-ones and a new series of 7-alkoxy-4H-[1,2,4]triazolo[4,3-d]benzo[b][1,4]thiazine derivatives were synthesized using 5-methoxybenzo[d]thiazol-2-amine as starting material. The structures of the compounds were elucidated by IR, (1)H-NMR spectroscopic data and microanalyses. The anticonvulsant activity of these compounds was evaluated by maximal electroshock (MES) test and rotarod test following intraperitoneal injection in KunMing mice. Among the synthesized compounds 3a-v, 7-(hexyloxy)-2H-benzo[b][1,4]thiazin-3(4H)-one (3f) could be considered potentially the most useful and safe therapeutic compound. Among the synthesized compounds 4a-u, compound 7-(2-fluorobenzyloxy)-4H-[1,2,4]triazolo[4,3-d]benzo[b][1,4]thiazine (4k) was the most active compound with an ED(50) of 17.0 mg/kg, TD(50) of 243.9 mg/kg and protective index (PI) of 14.3. Its neurotoxicity was lower than all the other synthesized compounds and also markedly lower than that of the reference drug carbamazepine.

Abstract
In this paper, the anticonvulsant characteristics of doxepin were evaluated in numerous experimental seizure models, including maximal electroshock (MES)-, pentylenetetrazole (PTZ)-, isoniazid (ISO)-, 3-mercaptopropionic acid (3-MP)-, bicuculline (BIC)-, thiosemicarbazide (THIO)-, and strychnine (STR)-induced seizures. In addition, the acute adverse-effect profile of doxepin with respect to impairment of motor coordination was assessed with a mouse rotarod test. The evaluation of the time-course and dose-response relationships for doxepin provided evidence that the peak maximum anticonvulsant activity and acute adverse effects occurred 5 min after intraperitoneal (ip) administration. The results also revealed that doxepin had excellent anticonvulsant activity against maximal electroshock-induced seizures in mice with a median effect value (ED(50)) of 6.6 mg/kg. The assessment of acute adverse effects in the rotarod test revealed that doxepin induced acute neurotoxicity, and its median toxic dose (TD(50)) was 26.4 mg/kg. Additionally, doxepin showed anticonvulsant activity in several chemically-induced seizure models, including ISO, 3-MP, BIC, and THI. Based on this study, we can conclude that the antidepressant drug doxepin may be useful for treatment of depression in patients with epilepsy due to its short time to peak maximum anticonvulsant activity after ip administration (5 min) and remarkable anticonvulsant activity (6.6 mg/kg).

Abstract
A series of 5-alkoxy-[1,2,4]triazolo[4,3-a]quinoline derivatives were synthesized using 4-hydroxyquinolin-2(1H)-one as the starting material. Their anticonvulsant activities were evaluated by the maximal electroshock test (MES) and their neurotoxicities were measured by the rotarod test. The results of these tests demonstrated that 5-hexyloxy-[1,2,4]triazolo[4,3-a]quinoline (3f) was the most potent anticonvulsant, with median effective dose (ED(50)) of 19.0mg/kg and protective index (PI=TD(50)/ED(50)) values of 5.8 in the MES test. Compound 5-benzyloxy-[1,2,4]triazolo[4,3-a]quinoline (3j), exhibited a little weaker activity than compound 3f in controlling the seizure induced by MES test at the dose of 22.8 mg/kg, but it possessed lower neurotoxicity with PI value of 12.0, which was safer than marketed drug carbamazepine. To explain the possible mechanism of anticonvulsant activity, compound 3j was tested in pentylenetetrazole test, isoniazid test, thiosemicarbazide test, 3-mercaptopropionic acid and strychnine test.

Abstract
A series of 2-substituted-7-heptyloxy-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinolin-1(2H)-ones was synthesized. The anticonvulsant effect and neurotoxicity of the compounds were calculated with maximal electroshock (MES) test, subcutaneous pentylenetetrazole (sc-PTZ), and rotarod tests with intraperitoneally injected mice. Among the synthesized compounds, 2-propionyl-7-heptyloxy-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinoline-1(2H)-one 4b was the most active one and also had the lowest toxicity. In the anti-MES potency test, it showed median effective dose (ED(50)) of 8.2 mg/kg, median toxicity dose (TD(50)) of 318.3 mg/kg, and the protective index (PI) of 39.0 which is much greater than the PI of the reference drugs phenytoin and carbamazepine.
