chaenomeles/neoplasms

Plant proanthocyanidins, including procyanidins, display various biological activities. Here we report an inhibition of human colon cancer Caco-2 cell growth by the extract from Japanese quince fruit and the procyanidin-rich fractions of the extract. We observed that the amount of apoptotic Caco-2

Chaenomeles speciosa Nakai is commonly used in traditional Chinese medicine for a variety of health-promoting effects. The present study aimed to investigate the antitumor effects of Chaenomeles speciosa Nakai. The tumor-inhibitory activity of the ethanol extract of Chaenomeles speciosa Nakai (EEC)

Natural polyphenols and polyphenol-rich extracts have been found to possess preventive and therapeutic potential against several types of cancers, including colorectal cancer (CRC), which is an example of an inflammation-associated cancer. This study examines the chemopreventive effect of a Japanese

Polyphenols are natural compounds of high structural diversity which translates into a very wide spectrum of biological activities, including chemoprevention. Here we report that a Japanese quince fruit flavanol preparation (JQFFP) caused favorable changes in Bax/Bcl-2 mRNA ratio, which rendered

In the course of our continuing search for bioactive constituents of Korean medicinal plants, we isolated five new oxylipins, chaenomic acid A-E (1-5), and six known ones (6-11) from the twigs of Chaenomeles sinensis. The structures of the new compounds (1-5) were determined by spectroscopic

Investigation of the MeOH extract of Chaenomeles sinensis twigs resulted in the isolation of seven biphenyl compounds (1-7) including a new compound, chaenomin (1). The chemical structures of the isolated compounds were elucidated by extensive NMR data ((1)H and (13)C NMR, (1)H-(1)H COSY, HSQC and

OBJECTIVE To investigate the effects of Glucosides of Chaenomeles speciosa (GCS) on rat adjuvant arthritis (AA) and to clarify the role of synoviocytes in this process. METHODS Complete Freund's adjuvant was used to induce AA in rats. Secondary paw swelling of AA rats was measured with MK-550 volume

OBJECTIVE To investigate the effects of Chaenomeles speciosa broth on immunoregulation for anti-tumor chemotherapy. METHODS Immunosuppressive model was induced by cyclophosphamide (CTX) in mice. The mice were treated with the broth for 15 days. The serum hemolysin was observed in mouse sera. Spleen

In this study, a water-soluble polysaccharide (CSP) was successfully purified from Chaenomeles speciosa by DEAE-Sepharose and Sephadex G-100 column chromatography. CSP had a weight-average molecular weight of about 6.3 × 10(4)Da and was composed of glucose (Glc), galactose (Gal), rhamnose (Rha) and

The present study aimed at investigating the structural features and antitumor properties of a novel heteropolysaccharide (CSP-W-2) obtained from the fruit of Chaenomeles Speciosa (Sweet) Nakai. CSP-W-2 demonstrate that they mainly contain glucose, galactose, arabinose, mannose, xylose in a ratio of

The Japan-China Joint Medical Workshop on Drug Discoveries and Therapeutics 2008 (JCMWDDT 2008) was held from September 29 to October 1, 2008 at The University of Tokyo, Tokyo, Japan. JCMWDDT is an international workshop that is mainly organized by Asian editorial members of Drug Discoveries &

The influence of procyanidin extract from Japanese quince fruit on the activities of matrix metalloproteinases MMP-2 and MMP-9 secreted to culture medium by human peripheral blood mononuclear cells (PBMC) and by human leukemia HL-60 cells was investigated by gelatin zymography. The extract proved to

Phenolic compounds are very important in the prevention and treatment of many civilization diseases, including colorectal cancer (CRC). In the present study we investigated and compared the phytochemical composition, antioxidant and cytotoxic activity of Japanese quince (Chaenomeles japonica L.)

Chaenomeles sinensis has been consumed traditionally for the treatment of throat diseases, diarrhea, inflammatory diseases, and dry beriberi. Repeated chromatography of the CHCl3-soluble fraction from the 80% MeOH extract of C. sinensis twigs led to the isolation of three new triterpenoids, sinenic

The design of mild and non-toxic synthesis of metallic nanoparticles is a topical subject in the nanotechnology field. The objective of this present study is to screen the bioactivity of biosynthesized nanoparticles by aqueous fruit extract of Chaenomeles sinensis. The reducing and stabilizing
