Constituents of Chinese Propolis and Their Antiproliferative Activities

Journal of Natural Products, 2002
Two new flavonoids, 3-O-[(S)-2-methylbutyroyl]pinobanksin (1) and 6-cinnamylchrysin (2), were isolated from the EtOAc-soluble fraction of the MeOH extract of Chinese propolis, along with 12 known compounds (3-14). The structures of the isolated compounds were elucidated on the basis of spectroscopic and chemical analyses.

Antiangiogenic and antiproliferative activity of suramin analogues

Cancer Chemotherapy and Pharmacology, 1997
The purpose of this study was to test the ability of 70 polyanionic analogues of suramin to inhibit angiogenesis. The ID50, the dose that produced 50% inhibition of angiogenesis, was determined for suramin and each of the analogues by measuring the ability of various amounts to inhibit angiogenesis in vivo in the chick egg chorioallantoic membrane (CAM)

Anticancer and antiproliferative activity of natural brassinosteroids

Phytochemistry, 2008
Brassinosteroids (BRs) are steroid plant hormones that are essential for many plant growth and developmental processes, including cell expansion, vascular differentiation and stress responses. Up to now the inhibitory effects of BRs on cell division of mammalian cells are unknown.

Antioxidant and Antiproliferative Activities of Common Fruits

Journal of Agricultural and Food Chemistry, 2002
Consumption of fruits and vegetables has been associated with reduced risk of chronic diseases such as cardiovascular disease and cancer. Phytochemicals, especially phenolics, in fruits and vegetables are suggested to be the major bioactive compounds for the health benefits.

Enhancement of antiproliferative activity by phototautomerization of anthrylphenols

Photochemical & Photobiological Sciences, 2015
An antiproliferative investigation was conducted on 3 human cancer cell lines, HCT 116 (colon), MCF-7 (breast), and H 460 (lung), on a series of 4 anthrylphenols in the dark and upon exposure to light (350 nm). 9-(2-Hydroxyphenyl)anthracene (1) moderately inhibited proliferation, but irradiation considerably enhanced the effect. The other anthracenes 4–

Antiproliferative activities of tea and herbal infusions

Food & Function, 2013
The consumption of tea and herbal infusions has increased rapidly in recent years. More and more people consume these infusions as daily beverages as well as for health purposes. The aim of this study was to supply new information on the antiproliferative function of these infusions for nutritionists and the general public.

Antiproliferative and Cytotoxic Activities

2018
Cancer is a genetic disease, affecting many people worldwide. Chemotherapy is routinely used for cancer treatment. However, this therapeutic approach is not always effective due to the development of cell resistance and toxic effects. Plants are a reservoir of natural chemicals with chemoprotective potential against cancer and with low adverse effects.

Synthesis and antiproliferative activity of 6-naphthylpterocarpans

Organic & Biomolecular Chemistry, 2020
The Heck-oxyarylation of 2H-chromenes afforded (6S*,6aR*,11aR*)-6-naphthylpterocarpans with potent antiproliferative activity. Absolute configurations and conformations of the separated enantiomers were determined by TDDFT-ECD calculations.

Antiproliferative activity of chalcones with basic functionalities

Bioorganic & Medicinal Chemistry, 2007
A library of chalcones with different basic groups were synthesized and evaluated for antiproliferative activities against the human breast cancer (MCF 7) and colon cancer (HCT 116) cell lines. Structure-activity relationships were analyzed by projection methods (PCA/PLS) and multiple linear regression.

Synthesis and antiproliferative activity of novel methylselenocarbamates

European Journal of Medicinal Chemistry, 2014
A series of new aliphatic, aromatic and heteroaromatic carbamate derivatives containing a methylseleno moiety were synthesized and evaluated in vitro for their cytotoxic activity against a panel of human cell lines including CCRF-CEM (lymphoblastic leukaemia), K-562 (lymphocytic leukaemia), HT-29 (colon carcinoma), HTB-54 (lung carcinoma), PC-3 ...
