    Abstract: Novel compounds having the formula: wherein the constituent variables are defined herein. The compounds are constructed to include a central aromatic, aliphatic, or heterocyclic ring system. Attached to the central ring system are two linear groups having nitrogenous moieties that are derivatized with chemical functional groups. The ring system can include further nitrogenous moieties, either as ring atoms or on pendant groups attached to the ring, that may also be derivatized with chemical functional groups. The totality of the chemical functional groups imparts certain conformational and other properties to the these compounds. In accordance with certain embodiments of the invention, libraries of such compounds are prepared utilizing permutations and combinations of the chemical functional groups and the nitrogenous moieties to build complexity into the libraries.

  • Patent number: 5977115
    Abstract: This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as selective 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 orthostatic 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.
