In vitro antiproliferative activity of partially purified Trigona laeviceps propolis from Thailand on human cancer cell lines

T. laeviceps propolis was found to contain compound(s) with antiproliferative activity in vitro on cancer but not normal cell lines in tissue culture. The more enriched propolis fractions typically revealed a higher antiproliferative activity (lower IC₅₀ value). Overall, propolis from Thailand may have the potential to serve as a template for future anticancer-drug development.
