Syzygium cumini (jamun) fruit-extracted phytochemicals exert anti-proliferative effect on ovarian cancer cells.

BACKGROUND

The medicinal properties of Syzygium sp., especially the antidiabetic property, date back to the ancient times. However, in the recent past, extracts from different parts of the Syzygium sp. have demonstrated promising anticancer activities in diverse cancer types, and now, attempts are being made to identify the active phytochemicals.

AIMS AND

OBJECTIVES

In this study, we intended to test the anticancer properties of phytochemicals extracted from the fruit of Syzygium cumini plant in ovarian cancer cells.

MATERIALS AND

METHODS

A total of nine phytochemicals extracted from the S. cumini fruits using chloroform were tested for their anticancer activity in the ovarian cancer cell line PA-1. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium assay was performed to calculate the 50% inhibition (IC50) concentration and cell cytotoxicity values. Cell scratch assay was performed to assess the proliferation inhibition activity of the phytochemicals. Cisplatin was used as positive control.

RESULTS

Out of the nine phytochemicals tested, quercetin (QC), gallic acid (GA), and oleanolic acid (OA) were found active. QC and GA were most effective with more than 90% cell cytotoxicity at 2.5 µ g/ml and above concentrations and OA moderately effective up to 5 µg/ml serial concentrations. Cell proliferation was significantly inhibited by QC and GA and moderately but significantly by OA.

CONCLUSION

Our data demonstrate the anticancer activity of QC, GA, and OA phytochemicals, which is consistent with the previous reports. However, this is the first report showing the anticancer activity of these phytochemicals derived from S. cumini in the ovarian cancer cells. These data suggest that there is a potential to develop these phytochemicals as anticancer therapeutic agents either as monotherapeutic agents or in combination with commonly used chemotherapeutic agents, which needs to be explored.
