In this paper, rGO/Pd–Fe3O4@PPy as an efficient stable nanocomposite was synthesized. To understand the synergetic effects of rGO, Pd, Fe3O4 and PolyPyrrole, the performance of rGO/Pd–Fe3O4@PPy as a heterogeneous recyclable nanocatalyst in the green synthesis of C-C and C-O coupling products, as well as different conditions are studied. Synthesized rGO/Pd–Fe3O4@PPy was characterized by FT-IR, XRD, FE-SEM, EDS, TGA and AFM analysis. Best results are obtained under sonication in H2O for C-C coupling and by ball-milling for C-O coupling. The benefits of this method include: green solvents and conditions, absence of external base, low reaction times with high yield and easy work-up method.

A series of 2-phenoxypyridine derivatives were prepared and evaluated for their inhibitory activity against the reverse and forward modes of the sodium-calcium exchanger (NCX). The structure-activity relationships of these compounds on the inhibitory activity for the sodium-calcium exchanger are discussed. The sodium-calcium exchanger (NCX) is known as the transporter that controls the concentration of Ca2+ in cardiac myocytes. In the setting of heart failure and myocardial ischemia-reperfusion, NCX underlies an arrhythmogenic transient inward current responsible for delayed after-depolarizations and nonreentrant initiation of ventricular tachycardia. NCX is an attractive target for treatment in heart failure and myocardial ischemia-reperfusion. We have designed and synthesized a series of phenoxypyridine derivatives, based on compound 3. These derivatives have been evaluated for their inhibitory activity against both the reverse and forward mode of NCX in CCL39 cells. We have discovered several novel potent NCX inhibitors (39q, 48k), which have a high selectivity for reverse NCX inhibitory activity.
