Abstract
Epilepsy is considered one of the most common neurological disorders worldwide; it needs long-term or life-long treatment. Despite the presence of several novel antiepileptic drugs, approximately 30% patients still suffer from drug-resistant epilepsy. Subsequently, searching for new anticonvulsants with lower toxicity and better efficacy is still in paramount demand. Using target-based studies in the discovery of novel antiepileptics is uncommon owing to the insufficient information on the molecular pathway of epilepsy and complex mode of action for most of known antiepileptic drugs. In this review, we investigated the properties of anticonvulsants, types of epileptic seizures, and mechanism of action for anticonvulsants.

Abstract
Aiming to develop novel anticonvulsant agents a new series of novel cycloalkanecarboxamide parabanic acid hybrids series 8, 9 and 10 possessing the essential structure requirements for anticonvulsant activity was synthesized starting from cycloalkanones. All final target compounds were primary screened for chemically and electrically induced seizures using pentylenetetrazole “scPTZ” and maximal electroshock seizure “MES” models. In phase I anticonvulsant evaluation compounds 8b and 10b exhibited the highest potency among all the target compounds with 100% protection towards chemically induced seizures. Results of phase II anticonvulsant screening showed that compounds 8b and 10b are more potent than standard drug ethosuximide by about 11 and 9 fold, respectively. Regarding MES test, compounds 8b and 9a-d exhibited 100% protection with ED50 values ranged between 0.107–0.177 mmol/Kg. All final compounds did not display any signs of motor impairment in the neurotoxicity screening test. Also, compounds 8a, 9a-d and 10b were devoid of hepatotoxicity as shown by measurement of serum levels of liver enzymes, albumin as well as total protein. Moreover, the cyclohexyl derivative 10b produced a significant increase of Gamma-aminobutyric acid “GABA” brain’s content of mice compared to control group confirmed its GABAergic modulating activity. Molecular docking, physicochemical and pharmacokinetic properties were carried out for all compounds as well. These outcomes support that cycloalkanecarboxamide parabanic acid hybrid is a promising scaffold to pave the way towards further development of novel class of antiepileptic drugs.

Abstract
The new series of 5a-e, 6a-e and 7a-e derivatives were designed, synthesized and tested for their anticonvulsant activity using "gold standard methods" ScPTZ and MES model, neurotoxicity, liver enzymes and neurochemical assay. Screening of the synthesized analogues exhibited variable anticonvulsant potential especially in chemically induced seizures. Quantification study showed that compounds 6d and 6e were the most potent analogues with ED50 44.77 and 11.31 mg/kg, respectively in ScPTZ test. Compound 6e (0.031 mmol/kg) was about 2 fold more potent than phenobarbital (0.056 mmol/kg) and was 30 folds more potent than Ethosuximide (0.92 mmol/kg) as reference standard drug. Moreover, all the synthesized compounds were screened for acute neurotoxicity using the rotarod method to recognize motor impairment, whereas all compounds devoid from neurotoxicity except compound 5a, 5b, 7a and 7e. The most active compounds were examined for acute toxicity and the estimates for LD50 were stated. Further neurochemical study was performed to investigate the effect of the most active compounds in ScPTZ test on GABA level in brain of the mice; a significant elevation in GABA level was obvious for compound 6d compared to control group confirming GABAergic modulating activity. Docking study was accomplished to examine the binding interaction of the newly synthesized analogues with GABA-AT enzyme. Additionally, physicochemical and pharmacokinetic parameters were predicted. The attained results indicate that the newly target compounds are considered a promising scaffolds for further development of newly anticonvulsants.

Abstract
GC-MS and HPLC analyses of the hydromethanolic extracts of the truffles Tirmania nivea (TN) and Tirmania pinoyi (TP) revealed the presence of 18 metabolites and 11 polyphenols, respectively. In vivo, TP extract protected against subcutaneous pentylenetetrazole (scPTZ) and maximal electric shock (MES)-induced convulsions faster than TN. TP (100 and 300 mg/kg) showed 100% protection and longer duration than TN in the scPTZ test. Similarly, at 300 mg/kg, TP demonstrated a quicker start (75%) and longer duration of action (100%) than TN in MES test. In scPTZ test, ED50 of TP demonstrated greater anticonvulsant efficacy than TN. In mice given TP and TN treatments, the brain GABA levels were noticeably increased. TP (100 and 300mg/kg) produced a notable sedative effect in open field test, whereas TN (100 or 300 mg/kg) and TP (300 mg/kg) reduced sleep latency by 79, 52, and 45%, respectively. In writhing test, TN (100 or 300mg/kg) significantly enhanced analgesic efficacy by 50 and 87%, respectively. Comparatively, in formalin test, TP and TN at a dosage of 300 mg/kg decreased the length of the licking by 34 and 59%, respectively. For the first time, this study explains the anticonvulsant, sedative, central, and peripheral analgesic activities of truffle extracts.

Abstract
Aiming to discover new antihyperlipidemic agents, a new set of quinazolinone-fibrate hybrids 9a-r bearing the essential features for peroxisome proliferator-activated receptor-α (PPARα) agonistic activity was synthesized and the structures were confirmed by different spectral data. All the target compounds were screened for their PPARα agonistic activity. Compounds 9o and 9q exhibited potent activity, with EC50 values better than that of fenofibrate by 8.7- and 27-fold, respectively. Molecular docking investigations were performed for all the newly synthesized compounds in the active site of the PPARα receptor to study their interactions and energies in the receptor. Moreover, the antihyperlipidemic and antioxidant activities of compounds 9o and 9q were determined using Triton WR-1339-induced hyperlipidemic rats. Compound 9q exhibited effective hypolipidemic activity in a dose-dependent manner, where it significantly reduced the serum levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and very-low-density lipoprotein cholesterol and increased the level of high-density lipoprotein cholesterol. Furthermore, it possesses a powerful antioxidant profile where it significantly elevated the levels of reduced glutathione as well as the total antioxidant capacity and significantly decreased the malondialdehyde level. The histopathological studies revealed that compound 9q improved the aortic architecture and hepatic steatosis. These findings support that compound 9q could be a promising lead compound for the development of new antihyperlipidemic agents.

Abstract
A new series of N-(2-((4-(1,3-diphenyl-1H-pyrazol-4-yl)pyridine sulfonamide derivatives 11a-o were designed and synthesized based on our previous works. The new series was tested for its anticancer and anti-inflammatory effects. The anticancer profile of final target compounds was obtained by testing them over 60 cell lines belong to nine types of cancers. Compound 11c showed the highest percent inhibition, so its potency was measured over the most sensitive cell line to determine its IC50 over each cell. In addition, compound 11c was tested over kinase panel to get its biological target(s). Compound 11c had strong activity over JNK1, JNK2, p38a and V600EBRAF. All final target compounds were tested against the four kinases to build a structure activity relationship. Compound 11c was subjected to cell cycle analysis to check at which phase is affected by 11c. The anti-inflammatory effect of final target compounds was screened by testing their ability to inhibit both nitric oxide release and prostaglandin E2 production on raw 264.7 macrophages in addition to test their cytotoxic effect on the same cells. Compound 11n showed the highest ability to inhibit prostaglandin E2 and all compound showed moderate to low activity regarding inhibition of nitric oxide release. Compound 11n was investigated for its ability to reduce Interleukin 6 and TNF-alpha. In addition, compound 11n was tested for its effect on induced Nitric oxide synthase (iNOS), and COX-2 mRNA expression level and its effect on nitric oxide synthase (iNOS), COX-1 and COX-2 protein levels where it showed selectivity for COX-2 compared to COX-1 and iNOS.

Abstract
Epilepsy is one of the commonly prevailing neurological disorders. According to the reports, it is evident that about 80% of the epileptic cases have been observed in developing countries. Although there are many drugs with significant potency available in the market; still there is an issue of selectivity and toxicity. Therefore, continuous attempts have been made by the researchers to develop newer therapeutic agents against epilepsy. Many synthetic strategies have been available in the literature to synthesize various classes of anticonvulsants with promising activity. In the presented review, authors have summarized some newer synthetic routes being used for the synthesis of nitrogen-containing anticonvulsants taking a cue from the reported established anticonvulsant drugs viz. vigabatrin, sodium valproate, oxcarbazepine, felbamate, retigabine, and gabapentin. Various derivatives with the substitution for better anticonvulsant profile have been described in the figures for easy comparative study. The structure-activity relationship (SAR) of compounds with maximum potency has also been discussed. This article may serve as a boost for the researchers to modify the pre-existing synthetic routes as well as to improve potency and yield of the compounds.
