Abstract
|
|
|
|
Ovarian cancer is a primary global health concern, often diagnosed at advanced stages with limited treatment options and poor prognosis. Natural products have emerged as potential sources of safe and effective therapies. From the seeds of Myristica fragrans Houtt. (nutmeg), 24 compounds, including neolignans and diarylnonanoid derivatives, were isolated and structurally elucidated. The cytotoxic activities of these isolated metabolites against cisplatin-sensitive and resistant human ovarian cancer cell lines were evaluated. In particular, myrifragranone C (23) exhibited cytotoxicity against all test cancer cell lines A2780, TOV-112D, and SK-OV3 with IC50 values of 14.1, 16.9, and 33.4 μM, respectively. Furthermore, compound 23 induced the death of A2780 and SK-OV3 cancer cells via apoptosis. Western blotting revealed that compound 23 significantly increased the expression of cleaved caspase-3 and poly-ADP ribose polymerase and promoted apoptosis via the mitogen-activated protein kinase signaling pathway. Our findings may provide a preliminary understanding of the anti-ovarian cancer effect of the active compound myrifragranone C as a potential treatment using natural products.
