The expression of protein kinase C (PKC) isoenzymes and the effects of PKC activation on myocardial phospholipase A2 (PLA2) activity, platelet-activating factor (PAF) generation and eicosanoid release were studied in spontaneously beating cultured rat cardiomyocytes. (unige.ch)

Finally, in vitro ADME and pharmacokinetic characterization of 18t further supports the prospects of the 3,5-diphenyl-2-aminopyridine scaffold for the generation of in vivo pharmacology probes of RIPK2 kinase and NOD cell signaling functions. (ox.ac.uk)
