The creosote bush (Larrea tridentata) accumulates a complex mixture of 8-8' regiospecifically linked lignans, of which the potent antioxidant nordihydroguaiaretic acid (NDGA) is the most abundant. Its tetra-O-methyl derivative (M4N) is showing considerable promise in the treatment of refractory

Dehydrozingerone, chalcone, and isoeugenol analogues as in vitro anticancer agents.

Numai utilizatorii înregistrați pot traduce articole

Twenty-eight compounds related to dehydrozingerone (1), isoeugenol (3), and 2-hydroxychalcone (4) were synthesized and evaluated in vitro against human tumor cell replication. Except for isoeugenol analogues 27-35, most compounds exhibited moderate or strong cytotoxic activity against KB, KB-VCR (a

Eugenol and isoeugenol, two components of clover oil, have been reported to possess several biomedical properties, such as anti-inflammatory, antimicrobial and antioxidant effects. This study aims to examine the anti-inflammatory effects of eugenol, isoeugenol and four of their derivatives on

A hexane fraction of guava Leaves (Psidium guajava L.) induces anticancer activity by suppressing AKT/mammalian target of rapamycin/ribosomal p70 S6 kinase in human prostate cancer cells.

Numai utilizatorii înregistrați pot traduce articole

This study was carried out to evaluate the anticancer effects of guava leaf extracts and its fractions. The chemical compositions of the active extracts were also determined. In the present study, we set out to determine whether the anticancer effects of guava leaves are linked with their ability to

Structure-activity relationship in potentially anti-tumor promoting benzalacetone derivatives, as assayed by the epstein-barr virus early antigen activation.

Numai utilizatorii înregistrați pot traduce articole

The in vitro anti-tumor promoting activities of antimutagenic benzalacetone (4-phenyl-3-buten-2-one), its monosubstituted derivatives and related compounds, cinnamaldehydes and cinnamic acids, were evaluated by determining the inhibitory effect on Epstein-Barr virus early antigen (EBV-EA) activation

Isoeugenol is a selective potentiator of camptothecin cytotoxicity in vertebrate cells lacking TDP1.

Camptothecin (CPT), a topoisomerase I (TOP1) inhibitor, exhibits anti-tumor activity against a wide range of tumors. Redundancy of TOP1-mediated repair mechanisms is a major challenge facing the efficiency of TOP1-targetting therapies. This study aims to uncover new TOP1 targeting approaches

Anethole blocks both early and late cellular responses transduced by tumor necrosis factor: effect on NF-kappaB, AP-1, JNK, MAPKK and apoptosis.

Anethole, a chief constituent of anise, camphor, and fennel, has been shown to block both inflammation and carcinogenesis, but just how these effects are mediated is not known. One possibility is TNF-mediated signaling, which has also been associated with both inflammation and carcinogenesis. In the

Predicting the biological activities of 2-methoxyphenol antioxidants: effects of dimers.

Selective cyclooxygenase (COX)-2 inhibitors have attracted much attention in relation to the design of non-steroidal anti-inflammatory agents (NSAIDs). The relationship between experimentally derived data on the antioxidant capacity, cytotoxicity and COX-2 inhibition for a range of 2-methoxyphenols

Inhibitory effects of dehydrozingerone and related compounds on 12-O-tetradecanoylphorbol-13-acetate induced Epstein-Barr virus early antigen activation.

Dehydrozingerone, 4-(4-hydroxy-3-methoxyphenyl)-3-buten-2-one, is half an analog of curcumin which is known to have anti-tumor activity. The anti-tumor promoting activity of dehydrozingerone was evaluated by determining the inhibitory effect on Epstein-Barr virus early antigen (EBV-EA) activation

Haloalkane induced hepatic insult in murine model: amelioration by Oleander through antioxidant and anti-inflammatory activities, an in vitro and in vivo study.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Nerium oleander L. (syn. Nerium indicum Mill, Nerium odorum Aiton) belongs to the family Apocynaceae. It is used for its anti-inflammatory, anti-diabetic, anti-cancer and hepatoprotective activities in traditional medicine. Previous pharmacognostic studies suggested that 70 %

Chemotypic variation of essential oils in the medicinal plant, Anemopsis californica.

Numai utilizatorii înregistrați pot traduce articole

Anemopsis californica (Saururaceae) commonly called yerba mansa, is an important medicinal plant in many deserts in the southwestern region of North America. Populations of A. californica, collected throughout New Mexico, were examined for chemical variability in roots and rhizomes for select

Dermal exposure to chemicals may result in allergic or irritant contact dermatitis. In this study, we performed ex vivo local lymph node assay: bromodeoxyuridine-enzyme-linked immunosorbent assay (LLNA: BrdU-ELISA) to compare the differences between irritation and sensitization potency of some

Eugenol and Its Role in Chronic Diseases.

Numai utilizatorii înregistrați pot traduce articole

The active components in cloves are eugenol and isoeugenol. Eugenol has recently become a focus of interest because of its potential role in alleviating and preventing chronic diseases such as cancer, inflammatory reactions, and other conditions. The radical-scavenging and anti-inflammatory
