RETRACTED: Synthesis of efficient cobalt–metal organic framework as reusable nanocatalyst in the synthesis of new 1,4-dihydropyridine derivatives with antioxidant activity

Frontiers in Chemistry, 2022
Efficient cobalt–metal organic framework (Co-MOF) was prepared via a controllable microwave-assisted reverse micelle synthesis route. The products were characterized by SEM image, N2 adsorption/desorption isotherm, FTIR spectrum, and TG analysis. Results

Cardioprotective Effect against Ischemia–Reperfusion Injury of PAK-200, a Dihydropyridine Analog with an Inhibitory Effect on Cl⁻ but Not Ca²⁺ Current

Biomolecules, 2023
We examined the effects of a dihydropyridine analog, PAK-200, on guinea pig myocardium during experimental ischemia and reperfusion. In isolated ventricular cardiomyocytes, PAK-200 (1 μM) had no effect on the basal peak inward and steady-state currents ...
