标 题:Synthesis of hydrogen peroxide
发明人：BECKMAN ERIC J; HANCU DAN
权利人:UNIV PITTSBURGH
摘要:A method for synthesizing hydrogen peroxide comprises the steps of: synthesizing an analog of anthraquinone that is miscible or soluble in carbon dioxide; reacting the analog of anthraquinone with hydrogen in carbon dioxide to produce a corresponding analog of tetrahydroquinone; and reacting the analog of tetrahydroquinone with oxygen to produce the hydrogen peroxide and regenerate the analog of anthraquinone. A chemical compound having the formula: n wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 are independently, the same or different, H, R C , or R S R C , wherein R S is a spacer group and R C is a fluoroalkyl group, a fluoroether group, a silicone group, an alkylene oxide group, a fluorinated acrylate group, or a phosphazine group, and wherein at least one of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 is not H.

标题 :Spirotricyclic substituted azacycloalkane derivatives and uses thereof
发明人：EVANS BEN E; HOFFMAN JACOB M; GILBERT KEVIN F; RITTLE KENNETH E
权利人:MERCK & CO INC
摘要:Spirotricyclic azacycloalkyl compounds and pharmaceutically acceptable salts thereof are disclosed. The synthesis of these compounds is also described. One application of these compounds, which are alpha 1a adrenergic receptor antagonists, is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia can be achieved.

摘要:Lactam and cyclic urea derivatives and their pharmaceutically acceptable salts are disclosed. The synthesis of these compounds and their use as alpha 1a adrenergic receptor antagonists is also described. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are typically selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia can be achieved.
