Atividade citotóxica e antiangiogênica de Punica granatum L., Punicaceae

Resumo

activities in vitro and in vivo. In this work, the in vitro cytotoxicity was evaluated using the K-562 cell line and Ehrlich ascites tumour cells, by MTT tetrazolium reduction test and the trypan blue exclusion test. In vivo studies investigated the increase in the survival time of Ehrlich tumour-bearing mice after treatment with different doses of Punica granatum L. ethanol extract (12.5; 25; 50 e and 100 mg/kg), by gavages, for ten consecutive days. In addition, we also investigated the tumour inhibition potential and antiangiogenic activity of this plant. In vitro results demonstrated a decrease of K-562 and Ehrlich ascites tumour cells viability, with both methods used, in a dependent-manner concentration. In vivo results showed a significant antitumor activity against Ehrlich ascites tumour growth, increasing survival time. In parallel, we detected a significant inhibition of the tumour growth, along with a decrease in the vascular pattern of the peritoneal wall. Thus, the data presented herein clearly showed that Punica granatum L. has antitumor and antiangiogenic activities.
