Quantitative Structure-Activity Relationship Studies of 4-Imidazolyl- 1,4-dihydropyridines as Calcium Channel Blockers

Objective(s): The structure- activity relationship of a series of 36 molecules, showing L-type calcium channel blocking was studied using a QSAR (quantitative structure–activity relationship) method. Materials and Methods: Structures were optimized by the semi-empirical AM1 quantum-chemical method which was also used to find structure-calcium channel blocking activity trends. Several types of ...

Interaction of lead acetate with calcium channel blockers in formalin test and formalin-induced inflammation

  In this study interaction of three types of calcium channel blockers nifedipine, diltiazem and verapamil on the effects of lead acetate on two types of pain (nociception and inflammation) induced by formalin in mice were examined. In order to study nociception, formalin test was selected because of greater resemblance to clinical pain. Lead acetate (50, 75, l00, 125 and 150 mg/kg) administere...

Computer simulations of structure-activity relationships for HERG channel blockers.

The hERG potassium channel is of major pharmaceutical importance, and its blockade by various compounds, potentially causing serious cardiac side effects, is a major problem in drug development. Despite the large amounts of existing biochemical data on blockade of hERG by drugs and druglike compounds, relatively little is known regarding the structural basis of binding of blockers to the channe...
