title: Selective killing effect of oxytetracycline, propafenone and metamizole on A549 or Hela cells.
abstract: OBJECTIVE
  To determine the selective killing effect of oxytetracycline, propafenone and metamizole on A549 or Hela cells.
  
  
  METHODS
  Proliferation assay, lactate dehydrogenase (LDH) assay, apoptosis detecting, flow cytometry and western blot were performed.
  
  
  RESULTS
  It was found that treatment with propafenone at the concentration of 0.014 g/L or higher for 48 h could induce apoptosis in Hela cells greatly, while it was not observed in oxytetracycline and metamizole at the concentration of 0.20 g/L for 48 h. Oxytetracycline, propafenone and metamizole all displayed evident inhibitory effects on the proliferation of A549 cells. The results of LDH assay demonstrated that the drugs at the test range of concentration did not cause necrosis in the cells. Propafenone could elevate the protein level of P53 effectively (P<0.01).
  
  
  CONCLUSIONS
  Oxytetracycline, propafenone and metamizol (dipyrone) all displayed evident inhibitory effects on the proliferation of A549 cells. Propafenone also displayed evident inhibitory effects on the proliferation of Hela cells.
