Abstract
Purpose: To evaluate the anti-cancer
potentials of a decoction of Flueggea. leucopyrus (Willd.)
on human endometrial carcinoma (AN3CA) cells.
Methods: Decoction was prepared by
boiling 60 g of the ground plant material in 1.6 L of
distilled water for about 3 h to reduce the volume to
200 mL and then freeze dried. The effect of the
decoction on AN3CA cells was determined by evaluating
its cytotoxicity by 3-(4, 5-dimethylthiazol-2yl) -2,
5-biphenyl tetrazolium bromide (MTT) and sulphorhodamine
B (SRB) assays, as well as its ability to modulate
apoptosis (microscopic observation of morphological
changes, DNA fragmentation and caspase activity). The
antioxidant activity of the decoction was also
determined by DPPH assay, and its total polyphenolic and
flavonoid content.
Results: The decoction exerted a
significant dose-dependent cytotoxicity on AN3CA cells
as evident from MTT assay IC50 values of
22.09 and 14.60 μg/mL at 24 and 48 h post-incubation,
respectively; and SRB assay IC50 values of
28.60 and 15.09 μg/mL at 24 and 48 h post-incubation,
respectively. The decoction also enhanced apoptosis as
shown by enhanced DNA fragmentation, microscopic
observation of nuclear condensation, fragmentation and
apoptotic bodies and enhanced caspase 3 and 9
activities, as well as moderately increased radical
scavenging activity.
Conclusion: The cytotoxic and apoptotic
effects demonstrated by F. leucopyrus (Willd.) decoction
provide supportive evidence for the ethnomedicinal use
of this plant for cancer therapy.
