denbinobin/adenocarcinoma

In the present study, we explore the role of apoptosis signal-regulating kinase 1 (ASK1) in denbinobin-induced apoptosis in human lung adenocarcinoma (A549) cells. Denbinobin-induced cell apoptosis was attenuated by an ASK1 dominant-negative mutant (ASK1DN), two antioxidants (N-acetyl-L-cysteine

OBJECTIVE Human pancreatic carcinoma is a highly malignant cancer. Previous studies have shown that the decoy receptor 3 (DcR3) for Fas ligand (FasL) plays significant roles in tumour progression and immune suppression. In the present study, we evaluated the anti-cancer activity of a natural

Increasing evidence demonstrated that denbinobin, isolated from Ephemerantha lonchophylla, exert cytotoxic effects in cancer cells. The purpose of this study was to investigate whether denbinobin induces apoptosis and the apoptotic mechanism of denbinobin in human lung adenocarcinoma cells (A549).

Denbinobin, which is a phenanthraquinone derivative present in the stems of Ephemerantha lonchophylla, has been demonstrated to display antitumor activity. Recent reports suggest that the enhanced activity of insulin-like growth factor-1 receptor (IGF-1R) is closely associated with tumor

The bane of anti-cancer therapy is usually the development of resistance to apoptosis in malignant cells. Identification of strategies to re-sensitize cancer cells to apoptosis has now become a top priority in anti-cancer research. Denbinobin is a novel, naturally occurring phenathroquinone isolated

Two phenanthrenes were isolated from the aerial part of Dendrobium nobile Lindl. and their structures were identified to be 4,7-dihydroxy-2-methoxy-9,10-dihydrophenanthrene (1) and denbinobin (2), among which the former has been first isolated from this plant. These two compounds were found to be
