Current Topics in Medicinal Chemistry - Volume 12, Issue 9, 2012

It has been my great pleasure to present before you the special issue that is intended to cover all major aspects of research devoted to the medicinal chemistry of anticonvulsant agents. The past few years have seen much progress in terms of research aiming to the new drug discovery of epilepsy. The number of publications in this field has risen steadily with novel and important results being reported in a variety of high Read More

The voltage-gated sodium channels (VGSCs) are a family of membrane proteins forming a pore, through which they selectively conduct sodium ions inward and outward cell's plasma membranes in response to variations of membrane potentials, playing a fundamental role in controlling cellular excitability. Growing evidences suggest that abnormal VGSCs are involved in the pathophysiology of both acquired and inherited Read More

Glutamate is the major excitatory neurotransmitter in the mammalian central nervous system (CNS) controlling physiological processes as learning and memory. However, the overactivation of glutamatergic neurotransmission is often related to various CNS chronic and acute diseases (epilepsy, ischaemia, Parkinson, etc.). This review will focus on the chemical structures, mechanism of action and main structure-activity relations Read More

The role of free radical-mediated reactions in human neuropathology continues to attract significant interest. Oxidative injury produced by free radicals may play a role in the initiation and progression of epilepsy and, therapies aimed at reducing oxidative stress may ameliorate tissue damage and favorably alter the clinical course. The prevalence of epilepsy increases with age, and mitochondrial oxidative stress is a le Read More

Synthesis of genome level expression data related to human epilepsy and animal models of epileptogenesis is a challenge because of differences in the use of animal species and strains, brain regions, methods to trigger epileptogenesis, tissue sampling time-points, epilepsy phenotype assessment, array platforms, normalization algorithms, cutoff points for identifying differentially expressed genes etc. Nevertheless, a c Read More

Major advances in antiepileptic drug therapy have taken place since 1950s. In the first period, several antiepileptic drugs (AEDs) such as phenobarbital, diphenylhydantoin, ethosuximide, carbamazepine, benzodiazepines and valproic acid were introduced to epilepsy treatment. After 1990 many new generation drugs (lamotrigine, topiramate, gabapentine, pregabaline, felbamate, lacosamide, levetiracetam etc.) have Read More

The use of current antiepileptic drugs has been questioned due to the nonselectivity of the drugs and the undesirable side effects posed by them. This led to an intensive investigation in this area worldwide during the past 10 years. There have been some significant outcomes and the findings are promising as far as drug efficacy and safety is concerned. This review covers the new anticonvulsant agents that have shown encou Read More
