Abstract
A variety of active chemicals found in medicinal plants can be used to develop new medications with few adverse effects. In vitro and in silico analyses were used to evaluate the anticancer properties of Juniperus procera fruit and leaf extracts. Here, we show that the methanolic extract from J procera fruit and leaf extracts inhibits 2 human ovarian cancer cell lines, A2780CP and SKOV-3. The leaf extract demonstrated strong cytotoxicity against A2780CP with an IC50 of 1.2 μg/mL, almost matching the IC50 of the anticancer medication doxorubicin (0.9 μg/mL). Higher antioxidant activity was observed in the fruit than leaf extract. The molecular docking results showed that the active component, podocarpusflavone A, was the best-docked chemical with the human topoisomerase II alpha enzyme. According to our knowledge, this is the first in vitro study to show the cytotoxicity of J procera extracts against the 2 previously described human ovarian cancer cell lines. The fact that the podocarpusflavone A molecule may have an inhibitory effect on the human topoisomerase II alpha enzyme was also revealed by this first in silico analysis. Our findings imply that the J procera fruit and leaf methanolic extract has anticancer characteristics that may guide future in vivo studies.
