摘要:
The present invention relates to a process for the preparation of 6-(4-chlorophenyl)-2,2-dimethyl-7-phenyl-2, 3-dihydro-1H-pyrrolizin-5-yl acetic acid, in which the key intermediate, 5-Benzyl-3,3-dimethyl-3,4-dihydro-2H-pyrrole is obtained by the hydrogenation of 2,2-dimethyl-4-oxo-5-phenyl-nitropentane. The invention also relates to the preparation of the intermediates occurring in the above process.
摘要:
In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a p-donor conjugated to a p-acceptor through a p-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.
摘要:
The present invention relates to compounds capable of acting as androgen receptor, antagonists, pharmaceutical formulations containing the same, and methods of use thereof. Such uses include, but are not limited to, use as antitumor agents, particularly for the treatment of cancers such as colon, skin and prostate cancer and to induce androgen receptor antagonist activity in a subject afflicted with an androgen-related affliction. Examples of androgen-related afflictions include, but are not limited to, baldness, hirsutism, behavioral disorders, acne, and uninhibited spermatogenesis wherein inhibition of spermatogenesis is so desired.
摘要:
The present invention pertains to certain ketones and reduced ketones and derivatives thereof which, inter alia, inhibit osteoclast survival, formation, and/or activity; and/or inhibit bone resorption, and more particularly to compounds of the formulae: (1) (2) wherein: Ar is independently a biphenyl, phenanthryl, fluorenyl, or carbazolyl, and is optionally substituted; R is independently a C2-10alkylene group, and is optionally substituted; -OR , if present, is independently -OH or -OR ; -OR , if present, is independently selected from: -O-R ; -O-C(=O)R ; -O-C(=O)OR ; -O-S(=O)2OR ; Q is independently -OH or -OR ; wherein: -OR , if present, is independently selected from: -O-R ; -O-C(=O)-R ; -O-C(=O)-O-R ; -O-C(=O)-O-SO3R ; -O-C(=O)-O-(CH2)n-COOR ; -O-C(=O)-(CH2)n-NR R ; -O-C(=O)-(CH2)n-NH-C(=O)R ; -O-C(=O)-(CH2)n-C(=O)-NR R ; -O-P(=O)(OR )(OR ); -O-R ; R , if present, is an organic group which incorporates a phosphonic acid group; with the proviso that if -OR is -O-R , then R is not a phenyl group substituted with a sulfonyl group; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, or prodrugs thereof. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit osteoclast survival, formation, and/or activity, and to inhibit conditions mediated by osteoclasts and/or characterised by bone resorption, in the treatment of bone disorders such as osteoporosis, rheumatoid arthritis, cancer associated bone disease, Paget's disease, aseptic loosening of prosthetic implants, and the like; and/or in the treatment of conditions associated with inflammation or activation of the immune system.
