Breast cancer is a public health concern worldwide. Prolonged exposure to estrogens has been implicated in the development of breast neoplasms. Epidemiologic and experimental evidence suggest a chemopreventive role of phytoestrogens in breast cancers. Resveratrol, a naturally occurring
Breast cancer is the second leading cause of death among women in the United States. Estrogens have been implicated as major risk factors in the development of breast neoplasms. Recent epidemiologic studies have suggested a protective role of phytoestrogens in prevention of breast and other cancers.
BACKGROUND
In past, numerous quantitative structure-activity relationship (QSAR) based models have been developed for predicting anticancer activity for a specific class of molecules against different cancer drug targets. In contrast, limited attempt have been made to predict the anticancer activity
In recent decades, bacterial and viral infections and chronic inflammatory response have emerged as important causes of cancer. Also, infections remain a significant cause of morbidity and mortality in cancer patients. In this work, carboxymethyl chitosan nanoparticles (CMC NPs) were synthesized in
A carcinogenesis bioassay of D & C Red No. 9, a pigment used in topical drugs and cosmetics, was conducted by feeding diets containing 1,000 or 3,000 ppm of the test substance (89.8% pure) to groups of 50 F344 rats of either sex for 103 weeks. Similar groups of 50 B6C3F1 mice received diets
Toluene is used to back-blend gasoline, as a chemical intermediate, and as a solvent; 920 million gallons were produced in the United States in 1988. Toxicology studies were conducted by administering toluene (greater than 99% pure) in corn oil by gavage to groups of F344/N rats and B6C3F1 mice of
15-lipo-oxygenases are one of the iron-containing proteins capable of performing peroxidation of unsaturated fatty acids in animals and plants. The critical role of enzymes in the formation of inflammations, sensitivities, and some cancers has been demonstrated in mammals. The importance of enzymes
Curcumin, a pigment isolated from rhizomes of Curcuma longa, is a potent cancer chemopreventive and chemotherapeutic agent and is now evaluated in phase III human clinical trials. This report describes an efficient synthesis of [(18) O2 ]-curcumin. [(18) O2 ]-Curcumin was prepared in three steps
Mononuclear [(p-cym)RuCl(pz4lut)]Cl (1) and dinuclear [{(p-cym)RuCl}2(μ-pz4lut)]Cl2 (2) complexes (p-cym = 1-isopropyl-4-methylbenzene) comprising of bis(pyrazol-1-yl)methane based heteroscorpionate ligand α,α,α′,α′-tetra(pyrazol-1-yl)-2,6-lutidine (pz4lut) have been synthesised from pz4lut ligand
Cancer is a leading cause of death all over the world. HGF/MET signaling pathway is involved in many cancers and its inhibition has great potential as an effective therapeutic intervention. A series of 1H-pyrrolo [2,3-b]pyridine derivatives has recently been identified with cytotoxic activity, and
The previously reported 1-(2,4-dihydroxy-5-methylphenyl)ethan-1-one (1), (1'Z)-2-(1',5'-dimethylhexa-1',4'-dieny1)-5-methylbenzene-1,4-diol (2), and 1,8-epoxy-1(6),2,4,7,10-bisaborapentaen-4-ol (5) together with four new structures of aromatic bisabolane-related compounds
Oxidative stress-induced neuroinflammation is the prominent feature of neurodegenerative disorders, and is characterized by a gradual decline of structure and function of neurons. Many biochemical events emerge thanks to the result of this neurodegeneration, and ultimately provoke neuroinflammation,
The translocator protein 18 kDa (TSPO) is an attractive target for molecular imaging of neuroinflammation and tumor progression. [(18)F]PBR06, a fluorine-18 labeled form of PBR06, is a promising PET TSPO radioligand originally developed at NIMH. [(11)C]PBR06, a carbon-11 labeled form of PBR06, was
