Interaction of some chalcone derivatives with calcium channels using a theoretical model

For several years, different drugs have been used to treat heart failure, such as digoxin, captopril, spironolactone, milrinone, levosimedam, dobutamine, and others. However, some of these drugs can produce secondary effects such as arrhythmia, cough, hyperkalemia, and others. Analyzing these data, this study aimed to evaluate the interaction of some chalcone derivatives (1-17) with calcium channels using theoretical models. It is important to mention that 7pjx protein, nifedipine, amlodipine, diltiazem, and verapamil were used as theoretical tools in the DockingServer program. The results showed differences in the interaction of chalcone derivatives compared with nifedipine, amlodipine, diltiazem, and verapamil drugs. Other data indicate that the inhibition constant (Ki) for chalcone analog 1 was lower compared with nifedipine, amlodipine, verapamil, and diltiazem. Besides, other results suggest that Ki for compound 11 was lower compared with nifedipine, verapamil, and diltiazem. All these data suggest that chalcone derivatives 1 and 11 could act as calcium channel inhibitors; this phenomenon could be translated into changes in blood pressure through a decrease in calcium intracellular levels. These data suggest that chalcone derivatives 1 and 11 could be good therapeutic alternatives to treat heart failure.
