An estimated 50 million people suffer epilepsy worldwide and 30% of the cases do not respond to current antiepileptic drugs (AEDs). Here, we report synthesis and anticonvulsant screening of new derivatives of nafimidone, a well-known member of (arylakyl)azole anticonvulsants. The compounds showed promising protection against maximal electroshock (MES)-induced seizures in mice and rats when administered via intraperitoneal (ip) and oral route. Especially, 5b, 5c, and 5i displayed outstanding activity in rats in MES test when given ip (ED : 16.0, 15.8, and 11.8 mg/kg, respectively). Additionally, 5l was active against 6 Hz and corneal-kindled mice models. Behavioral toxicity of the compounds was very low and their therapeutic indexes were high compared to some currently available AEDs. A number of pharmaceutically relevant descriptors and properties were predicted for the compounds in silico in comparison with a set of known drugs. Favorable results were obtained such as good blood-brain barrier permeability and high oral absorption, as well as drug-likeness. 5l was found to show affinity to the benzodiazepine binding site of A-type GABA receptor via molecular docking simulations.

The zebrafish is a model organism that allows in vivo studies to be performed at a scale usually restricted to in vitro studies. As such, the zebrafish is well suited to in vivo screens, in which thou...
It is commonly held that in vivo biological experimental models are concrete and non-fictional. This belief is primarily supported by the fact that in vivo studies involve biological models which are ...
The treatment of epilepsy remains difficult mostly since almost 30% of patients suffer from pharmacoresistant forms of the disease. Therefore, there is an urgent need to search for new antiepileptic d...
The purpose of the current study is to determine if pre-exposure through video modeling will enhance testing compliance in a population of children who are receiving a diagnostic evaluatio...
By obtaining clinical specimens from participants with high-grade bone and soft tissue sarcomas to establish and profile as freshly implanted tumors in mice, the aim of this study is to id...
The study is being done to understand why some patients with epilepsy (disease of recurrence of seizures) do not respond very well to drug treatment with anticonvulsants. Despite the avai...

Dexmedetomidine is an alpha-2 agonist commonly used during neurosurgery due to its unique properties as a sedative and anxiolytic with minimal respiratory depression. Neurosurgical patie...
Procedures by which protein structure and function are changed or created in vitro by altering existing or synthesizing new structural genes that direct the synthesis of proteins with sought-after properties. Such procedures may include the design of MOLECULAR MODELS of proteins using COMPUTER GRAPHICS or other molecular modeling techniques; site-specific mutagenesis (MUTAGENESIS, SITE-SPECIFIC) of existing genes; and DIRECTED MOLECULAR EVOLUTION techniques to create new genes.
The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.
A multiribosomal structure representing a linear array of RIBOSOMES held together by messenger RNA; (RNA, MESSENGER); They represent the active complexes in cellular protein synthesis and are able to incorporate amino acids into polypeptides both in vivo and in vitro. (From Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
EPIDEMIOLOGIC STUDIES based on the detection through serological testing of characteristic change in the serum level of specific ANTIBODIES. Latent subclinical infections and carrier states can thus be detected in addition to clinically overt cases.
Studies designed to examine associations, commonly, hypothesized causal relations. They are usually concerned with identifying or measuring the effects of risk factors or exposures. The common types of analytic study are CASE-CONTROL STUDIES; COHORT STUDIES; and CROSS-SECTIONAL STUDIES.
