Activation of survival pathways has been associated with chemoresistance and progression of androgen independence which places a major obstacle to successful treatment of metastatic prostate cancer. Deguelin, a rotenoid isolated from Mundulea sericea, has an anticancer effect against several types
Deguelin, a plant-derived rotenoid, mediates potent chemopreventive responses through transcriptional regulation of phorbol ester-induced ornithine decarboxylase (ODC) activity. To explore the mechanism of this effect, the activity of this compound was evaluated with a number of model systems. Using
The natural compound deguelin has promising preventive and therapeutic activity against diverse cancers by directly binding to heat shock protein-90 and thus suppressing its function. Potential side effects of deguelin over a certain dose, however, could be a substantial obstacle to its clinical
Survivin plays important roles in maintaining cell proliferation and survival and promoting tumorigenesis. The present study was conducted to determine the stage of lung carcinogenesis at which survivin expression is induced and to investigate how survivin affects the chemopreventive action of
This perspective on Murillo et al. (beginning on page 942 in this issue of the journal) examines the potential of the naturally derived agent deguelin to prevent mammary tumorigenesis. These investigators showed that deguelin inhibits wnt/beta-catenin signaling in breast cancer cell lines, in
Deguelin, a natural product isolated from Mundulea sericea (Leguminosae), was shown previously to mediate strong inhibition of 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ornithine decarboxylase (ODC) activity in cell culture and to reduce the formation of preneoplastic lesions when mouse
On the basis of deguelin, a series of the B,C-ring truncated surrogates with N-substituted amide linkers were investigated as HSP90 inhibitors. The structure activity relationship of the template was studied by incorporating various substitutions on the nitrogen of the amide linker and examining
Lung cancer is the leading cause of cancer-related death among both men and women every year, mainly due to metastasis. Although natural compound deguelin has been reported to inhibited cell migration and invasion in various cancer cells, the details of this regulation progress remain to be fully
A series of O-substituted analogues of the B,C-ring truncated scaffold of deguelin were designed as C-terminal inhibitors of heat shock protein 90 (HSP90) and investigated as novel antiproliferative agents against HER2-positive breast cancer. Among the synthesized compounds, compound 80 exhibited
Hexokinases II (HK2) is a hub in the regulation of cancer cell glycolysis. Here we reported deguelin, a natural compound which has been studied in various tumor types, has a profound anti-tumor effect on human non-small cell lung cancer (NSCLC) via directly down-regulating of glycolysis. In NSCLC
In order to investigate the anti-cancer effects of deguelin and on K562 and K562/ADM cells in vitro and the underlying molecular mechanism and compare the cytotoxicity of deguelin on K562, K562/ADM cells and human peripheral blood mononuclear cells (PBMCs). The effects of deguelin on cell
During the pathogenesis of gastric cancer, Akt signaling is considered as a pivotal inducer of gastric cancer development. Here we report the identification of anticancer activities of deguelin, a natural agent that inhibits Akt signaling. When applied to MGC-803 and MKN-45 cells, deguelin
Deguelin, a natural rotenoid isolated from several plants, has been reported to exert anti-tumour effects in various cancers. However, the molecular mechanism of this regulation remains to be fully elucidated. Here, we found that deguelin inhibited the growth of non-small cell lung cancer (NSCLC)
Deguelin is a naturally occurring rotenoid with marked chemopreventive and antitumor activity. Cisplatin, characterized by damaging DNA, is widely used in the chemotherapy of malignancies, including gastric cancer. The present study investigated whether synergistic effects exist between the
Non-small cell lung cancer is a lethal malignancy with a high mortality rate. Deguelin displays an anti-tumor effect and inhibits metastasis in various cancers. The aberrant expression of NIMA-related kinase 2 (NEK2) indicates poor prognosis and induces epithelial-to-mesenchymal transition (EMT) and
