标 题 :Isotopically-stabilized tetronimide compounds
发明人:OLSEN MARK JON; SEERDEN JEAN PAUL
权利人:UNIV MIDWESTERN
摘要:Isotopically-stabilized tetronimide compounds comprising one or more deuterium atoms, derivatives, and intermediates, thereof, including methods for their synthesis, pharmaceutical compositions thereof, and methods of using these compounds to interact with target molecules in cell-free samples, cell- and tissue-based assays, animal models, and in a subject are disclosed. One aspect relates to molecules that modulate the expression or catalytic activity of aspartyl (asparaginyl) β-hydroxylase (ASPH) within or on the surface of a cell. Other aspects of the invention relate to use of the molecules disclosed herein to diagnose, ameliorate, or treat cell proliferation disorders and related diseases. Related aspects include uses of the compounds to modulate the activity of viruses, as anti-hyperlipidemia agents, and as agents to ameliorate or treat thrombosis and related cardiovascular and metabolic disorders.

标 题 :Alpha 1a adrenergic receptor antagonists
发明人:PATANE MICHAEL A; BOCK MARK G

摘要:This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenergic receptor antagonists. One application of these compounds 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 are achieved.
