Resumo

In this study, ultra-high performance liquid chromatography-mass spectrometry and tandem mass spectrometry of selected ions were used to characterise the ethanolic extract of a sample of Brazilian red propolis (EEBRP) and an active fraction (BRP-IV) containing xanthochymol and formononetin. The antiproliferative effect of BRP-IV was assayed using melanoma tumour xenografts in mice and HL-60, K562, RPMI8226, B16F10 cell lines. This fraction inhibited growth of tumour cell lines with IC50 values of 20.5 +/- 2.4 to 32.6 +/- 2.6 mu g/mL while EEBRP induced cytotoxic effect with IC50 values of 29.7 +/- 1.5 to 42.1 +/- 8.7 mu g/mL. BRP-IV also inhibited the proliferation of B16F10 cells by blocking cell cycle progression in the G2/M phase and inducing apoptosis. Administration of 10 mg/kg/day BRP-IV suppressed the growth of B16F0 tumour xenografts in C57BL/6 mice with less general toxicity than control groups. Taken together, these results indicate that BRP-IV can be considered a promising anticancer drug for the treatment of human cancers. (C) 2014 Elsevier Ltd. All rights reserved. (AU)
