Genetic and physiological studies have established a link between potassium channel dysfunction and a number of neurological and muscular disorders. Many 'channelopathies' are accounted for by a dominant-lethal suppression of potassium channel function. In the cardiac I(KS) channel complex comprising the alpha and beta subunits, KvLQT1 and IsK, respectively, several mutations lead to a dominant...

Niflumic acid, 2-{[3-(trifluoromethyl)phenyl]amino}pyridine-3-carboxylic acid (NFA), a nonsteroidal anti-inflammatory drug that blocks cyclooxygenase (COX), was shown previously to activate [Na(+)](i)-regulated Slo2.1 channels. In this study, we report that other fenamates, including flufenamic acid, mefenamic acid, tolfenamic acid, meclofenamic acid, and a phenyl acetic acid derivative, diclof...

Non-steroidal anti-inflammatory drugs are commonly prescribed in dental practice after minor oral surgical procedures such as tooth extraction. Diclofenac sodium is one of the non-steroidal antiinflammatory drugs widely used for pain relief in dentistry. Although adverse reactions to these drugs are rare, at times they can cause a life-threatening phenomenon. Stevens-Johnson syndrome is one suc...

In traditional molecular mechanics force fields, intramolecular non-bonded interactions are modelled as intermolecular interactions, and the form of the torsion potential is based on the conformational profiles of small organic molecules. We investigate how a separate model for the intramolecular forces in pharmaceuticals could be more realistic by analysing the low barrier to rotation of the p...

calcium mobilization is known to be an important factor in the activation of cells involved in inflammation,so,calcium-channel antagonists are be expected ti exhibit antiinflammatory activity.in the present study,we evaluateted the antiinflammatory effects of two calcium channel blockers,verapamil and nifedipine on adjuvant induced chronic in flammation in rat paw.sixty adult male rats were div...

Clostridioides difficile infection (CDI) is a worldwide concern. The increase in cases numbers and disease severity mortality combined with the scarcity of effective antibiotics warrant intensive research for alternative strategies to combat this disease. Although CDI inflammatory nature, antiinflammatory agents are not recommended management symptoms. Further, some drugs considered predisposin...
