Spiro Patents (Class 514/212.02)
  • Patent number: 6387893
    Abstract: 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.

  • Patent number: 6316437
    Abstract: Spirohydantoin compounds 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.

  • Patent number: 6271264
    Abstract: The present invention relates to a method for sequestering bile acids in a patient and to particular polymers for use in the method. The method comprises administering a therapeutically effective amount of a spirobicyclic ammonium moiety-containing polymer composition to a mammal, such as a human, whereby bile acids are sequestered. The polymers of the invention comprise spirobicyclic ammonium moieties and optionally, further comprise a hydrophobic substituent, a quaternary ammonium-containing substituent or a combination thereof.
