Abstract:
There are disclosed aryl-ethylene aromatic compounds and their use as organic semiconductors. The compounds can be used in electronic devices such as organic thin film transistors (OTFTs), display devices, light-emitting diodes, photovoltaic cells, photo-detectors, and memory cells. Methods for manufacturing these aryl-ethylene aromatic compounds are also disclosed.
Abstract:
The invention relates to plant extracts and bioactive molecules derived from the plant genus Acronychia and their use as antioxidants, antibacterials, anthelmintic, anti-inflammatories, cancer chemopreventatives, food additives and fragrance components in pharmaceuticals, nutraceuticals, foods and cosmetics.
Abstract:
The present invention provides convergent processes for preparing (-)-beta-elemene, (-)-beta-elemenal, (-)-beta-elemenol, and (-)-beta-elemene fluoride and analogues thereof. Also provided are intermediates useful for preparing (-)-beta-elemene. The present invention further provides novel compositions based on analogues of (-)-beta-elemene, (-)-beta-elemenal, (-)-beta-elemenol, (-)-beta-elemene fluoride and methods for the treatment of cancer, such as brain tumor, lung cancer, breast cancer, prostate cancer, ovarian cancer, colorectal cancer, gastric intestional cancer, and stomach cancer. The inventors propose a combination therapy using 1) one or more of the following anti-cancer agents: including, but not limited to, Cisplatin, 5-FU, Taxol, Taxol derivatives, and any anti-cancer agent, and 2) one or more of the following (-)-beta-elemene and its analogs, including (-)-beta-elemene, (-)-beta-elemenol, (-)-beta-elemenol, (-)-beta-elemene fluoride, and their analogs, and (-)-beta-elemene's intermediate in its chemical synthesis, for the treatment of cancer, especially for the treatment of brain tumor, lung cancer, ovarian cancer, bladder cancer, cervical cancer,. colon cancer, breast cancer, and prostate cancer.
Abstract:
The novel isomeric alkenes having structure (I) or (II) or (III) exhibit interesting odour characteristics, generally floral in nature, and so find use in perfumes and in perfumed products. The alkenes are also useful as intermediates in the preparation of other compounds, particularly other fragrance compounds, such as 3-(2-methylpropyl)-1-methylcyclohexanol.
Abstract:
La présente invention concerne de nouveaux dérivés du sulfolène et plus particulièrement le 4,4-diméthyl 2,2-dioxo 1, 2, 4, 5, 6, 7-hexahydrobenzo[c] thiophène. Ces dérivés sont préparés par mise en contact de la myrcène sulfone avec un acide fort. Les dérivés de la présente invention sont utilisés comme intermédiaires de synthèse dans la préparation de la vitamine A.
