Through pharmacophore models and providing quantitative analysis of structure-activity relationships (QSAR), molecular modeling techniques can be useful tools to study the interactions of ion channels and their modulators. The present review focuses on molecular modeling approaches that defined pharmacophore models of ion channel modulators in the CNS. The commonality and subtlety of the pharmacophore models of Read More

A review is presented on quantitative structure-activity relationship (QSAR) studies on cholecystokinin antagonists. Cholecystokinin (CCK) is a gastrointestinal peptide hormone closely related chemically to gastrin. However, its receptors are found in both peripheral and central nervous systems. Those present in peripheral system have been termed as CCK-A receptors and those present in central nervous system as CCK Read More

Cognition enhancers are drugs able to facilitate attentional abilities and acquisition, storage and retrieval of information, and to attenuate the impairment of cognitive functions associated with head traumas, stroke, age and age-related pathologies. Development of cognition enhancers is still a difficult task because of complexity of the brain functions, poor predictivity of animal tests and lengthy and expensive clinical trials. Read More

The 5-HT1A receptor has been extensively studied over the last two decades. There is a plethora of information describing its anatomical, physiological and biochemical roles in the brain. In addition, the development of selective pharmacological tools coupled with our understanding of psychiatric pathology has lead to multiple hypotheses for the therapeutic utility of 5-HT1A agents and in particular 5-HT1A receptor anta Read More

Although the etiology of drug psychosis or schizophrenia is still unknown, molecular and biochemical researches have recently made significant advances in the search for the candidate genes of these disorders. Among such studies are animal models of drug psychosis or schizophrenia such as amphetamine-induced behavioral sensitization or phencyclidine-treated animals. In this review, it is suggested that amphetamine or Read More
