1,4-Dihydropyridines are a group of pyridine-based molecules possessing a magnificent set of biological and therapeutic potentials. Belonging to the class of calcium channel blockers, they are known to be effective in the conditions, angina, hypertension, myocardial infarction and show vasodilatory and cardiac depressant effects. Hypotensive, antimicrobial, anticancer, anticoagulant, antioxidant, anticonvulsant, antimalarial, antiulcer, and neuroprotective effects have been reported with their rational use. The effects are precipitated in response to inhibition of calcium channels, gradually restricting calcium influx. Drugs like nifedipine, felodipine, and amlodipine are commonly used clinically. Several other drugs belonging to this class have been under clinical trials. The present review focuses on the various 1,4-dihydropyridine derivatives and their pharmacological actions.

AbstractIt was evidenced that saturated fatty acids (FAs) have a detrimental effect on pancreatic β-cells function and survival, leading to endoplasmic reticulum (ER) calcium release, ER stress, and apoptosis. In the present study, we have tested the effect of three calcium influx inhibitors, i.e., diazoxide, nifedipine, and verapamil, on the apoptosis-inducing effect of saturated stearic acid (SA) in the human pancreatic β-cell lines NES2Y and 1.1B4. We have demonstrated that the application of all three calcium influx inhibitors tested has no inhibitory effect on SA-induced ER stress and apoptosis in both tested cell lines. Moreover, these inhibitors have pro-apoptotic potential per se at higher concentrations. Interestingly, these findings are in contradiction with those obtained with rodent cell lines and islets. Thus our data obtained with human β-cell lines suggest that the prospective usage of calcium channel blockers for prevention and therapy of type 2 diabetes mellitus, developed with the contribution of the saturated FA-induced apoptosis of β-cells, seems rather unlikely.
