Synthesis of 2-amino-4, 5-diarylpyrimidines and their protective effects against oxygen-glucose deprivation in PC12 cells / 药学学报

A series of 6 novel 2-amino-4, 5-diarylpyrimidines were synthesized by the reaction of isoflavones with guanidine. They were identified by the spectra of IR, 1H NMR, 13C NMR and elemental analysis. The protective effects of 2-amino-4, 5-diarylpyrimidines against oxygen-glucose deprivation leading by sodium hydrosulfite in PC12 cells were studied by MTT method. It was shown that 2-amino-4, 5-diarylpyrimidines exhibited neuroprotective effects against oxygen-glucose deprivation injury in PC12 cells, which could increase the amount of survival PC12 cells and reduce their injured degree in the model.
