ABSTRACT

In the present study, we demonstrate that ipobscurine, an indole alkaloid fraction isolated from Ipomoea obscura, can reduce the formation of B16F-10 melanoma–induced metastatic nodules and inhibit the proliferation, migration, and invasion of B16F-10 melanoma cells in vitro, possibly by inhibiting pro-metastatic genes such as matrix metalloproteinases (MMPs) and inflammatory mediators such as cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and pro-inflammatory cytokines. Ipobscurine may also promote apoptosis by up-regulating pro-apoptotic molecules such as caspase-3, p53, and Bax and by down-regulating anti-apoptotic Bcl-2. In addition, we have observed that ipobscurine suppresses various transcription factors such as nuclear factor-κB (NF-κB) and activator protein, which are possibly associated with the suppression of apoptosis in cancer cells. Ipobscurine has also been shown to inhibit cell growth with arrest at G1 and reduce transition to the S and G2/M phases of the cell cycle.
