OBJECTIVE
Phenethyl caffeate benzoxanthene lignan (PCBL) is a synthetic compound with DNA interacting, antiangiogenic, antiproliferative and tumor cell death inducing abilities. Though PCBL exhibits the qualities of a prospective antitumor agent, the basic mechanism of PCBL induced cell death
In the present study, we investigated the effect and molecular mechanism of ethyl caffeate (EC), a natural phenolic compound isolated from Ligularia fischeri, on human ovarian cancer cell proliferation and progression. EC-mediated inhibition of cell proliferation in SKOV-3 cells was accompanied by
OBJECTIVE
Sodium caffeate (SC), the sodium salt of caffeic acid, was synthesized in our laboratory. We studied the antimetastatic effect induced by SC and its inhibition of tumor angiogenesis using various in vitro and in vivo metastasis assays.
METHODS
The in vivo inhibitory effect of SC on
OBJECTIVE
The purpose of the present study was to investigate the anticancer activity of bornyl caffeate in the human breast cancer cell line MCF-7.
METHODS
The cell viability was determined using the MTT assay, and apoptosis was initially defined by monitoring the morphology of the cell nuclei and
The Apc(Min/+) mouse model and the azoxymethane (AOM) rat model are the main animal models used to study the effect of dietary agents on colorectal cancer. We reviewed recently the potency of chemopreventive agents in the AOM rat model (D. E. Corpet and S. Tache, Nutr. Cancer, 43: 1-21, 2002). Here
Extracts of Cimicifuga racemosa (L.) Nutt. (syn.: Actaea racemosa L.) (CR) inhibit the proliferation of the human prostate cancer cell line LNCaP. Recently, the phenylpropanoid ester 3,4-dihydroxyphenacyl caffeate (petasiphenone, 1) was isolated from CR. This substance is a structural homologue to
OBJECTIVE
To develop a high-throughput screening system to measure the conversion of testosterone to dihydrotestosterone (DHT) in cultured human prostate cancer cells using turbulent flow chromatography liquid chromatography-triple quadrupole mass spectrometry (TFC-LC-TQMS).
RESULTS
After optimizing
OBJECTIVE
To study the anticancer activity of sodium caffeate (SC).
METHODS
A nucleoside transport assay was used to analyze the inhibitory effects of SC on nucleoside rescue. The MTT assay was used to measure cell proliferation. Flow cytometry was used to measure the apoptosis of BEC-7402 induced
In the continuing search for novel antiinflammatory agents, six flavonoids, namely kaempferol (1), ombuin (2), kaempferol 7,4'-dimethyl ether 3-O-beta-D-glucopyranoside (3), kaempferol 3-O-beta-D-glucopyranoside (4), isorhamnetin 3-O-beta-D-glucopyranoside (5) and hesperidin (6), together with one
For decades, skin cancer incidence has increased, mainly because of oncogenic signaling pathways activated by solar ultraviolet (UV) irradiation (i.e., sun exposure). Solar UV induces multiple signaling pathways that are critical in the development of skin cancer, and therefore the development of
The chemopreventive and antineoplastic activities of caffeic acid derivatives are highly dependent on the chemical structures and cancer cell types. The objective of the present study was to investigate the cytotoxicity of bornyl caffeate and the underlying molecular mechanisms in rat
Caffeic acid (CA) is distributed widely in nature and possesses strong antioxidant activity. However, CA has lower solubility in non-polar media, which limits its application in fat-soluble food. To increase the lipophilicity of natural antioxidant CA, a series of alkyl caffeates were synthesized
OBJECTIVE
To study the synergistic antitumor effect of sodium caffeate (sodium 3,4-dihydroxycinnamate, CA-Na) and mitomycin C (MMC).
METHODS
MTT assay, Western Blotting analysis and flow cytometry were used to determine the effects of MMC alone and in combination with CA-Na on tumor cell
Patrinia heterophylla Bunge, known as "Mu-Tou-Hui" in China, is distributed in most provinces and regions of China. As a traditional medicinal plant, which was first found in <Ben- Cao-Gang- Mu>. In many traditional herbal books, there are records of We recently reported that Phenethyl caffeate benzoxanthene lignan (PCBL), a semisynthetic compound derived from Caffeic Acid Phenethyl Ester (CAPE), induces DNA damage and apoptosis in tumor cells. In this study, we further investigated whether PCBL induces autophagy in WiDr cells. We also analyzed
