| Summary: | Artocarpus species are rich in phenolic compounds including flavonoids, stilbenoids,
arylbenzofurons and Jacalin which support their pharmacological properties as a medicinal
sources. Previous pharmacological studies of the natural products from Artocarpus sp have
established their mode of action in treatment of various diseases and other health benefits.
Therefore, in this study two flavonoid compounds from Artocarpus lowii, 2,4-dihydroxy-4-
methoxy-3prenyldihydrochalcone ( dihydrochalcone) and 2,4-dihydroxy-3,4-(2,2-
dimethylchromene)chalcones (chalcone) were tested for antiproliferative activity on human
adenocarcinoma breast cancer cell lines, MCF-7 and MDA-MB-23 I. The findings showed
that both of the compounds, dihydrochalcone and chalcone had IC50 lower than 20 ~g/mL
which were of good cancer therapeutic value on the above mention cancer cell lines.
However, dihydrochalcone had the best IC50 value which was 1.023 ~g/mL on MCF-7 cell
line. This compound also inhibits the growth of normal cell line, L929 but at higher IC50
value which is 1.659 ~g/mL. Mode of cell death caused by the compound was further
tested by using Hoechst 33258 staining for apoptosis . The apoptotic features were seen in
the treated cancer cells. Flow cytometry analysis also had been done as complement to
Hoechst staining which revealed a small number of apoptotic cells. It is concluded that
dihydrochalcone compound from A.lowii exert anticancer effect on MCF-7 breast cancer
cell line through apoptosis. The results inspire future advanced studies in order to produce
an anticancer drug from this plant. |
